Could it be a fuse or some thing simple? It was working great last night.

merry, there are 2 knobs on the back. Are they BOTH turned up to full? Sometimes one can get touched and dial it off.

I never use any processing in SR6005. It always runs in Pure direct mode regardless is it a music, youtube or BD movies. What ever I claim about SR6005 is based on it being set in Pure Direct. DAC in SR6005 is low end and Audissey - I have no idea why someone would like to ruin the SQ by using additional sound processing.

After speaking to parasound they suggested replacing the internal fuses. $3 and a radio shack visit later, all is fixed!

Audyssey is not processing, its just an autoEQ.
But I also do not use autoEQ (HK EZset) for music, and most of the time not for movies either. But if I am streaming movies, which is most of the time, I use either DTS neo6, or Harman's L7 to convert the stereo sound to 6 channel.
If I am using the Denon DVD player, I can output the soundtrack in direct mode, if I choose to do so.

Audyssey is DSP processing.

That is correct. It is a digital filter which is a recursive equation. In other words it mixes up consecutive samples and therefore needs digital input in form of PCM. Output from OPPO-105 is analogue so it does not make sense to redigitize and use inferior AVR DAC. So the whole AVR should stay out of loop except of attenuator. It means that all I need is a simple analogue preamp plus HDMI switch. May be some crappy DAC would not hurt to handle low quality source that do not come from OPPO. If I need a phono amp I can buy separate one. That is all I need. So all those AV preamp from Marantz, ONKYO and other mass market manufacturers has no value for me. The closest thing I need is Emotiva UPC-200 except it does not have stereo XLR in/outs. I do not need 5 channel XLR since OPPO has only stereo XLR output. That is my philosophy regarding preamps. When I was doing amplifiers myself I included simple preamp as a first stage of amp (no filter, nothing - just class A amp and mechanical switch), but it was long time ago before all those 7.1 stuff when sources were pure stereo music from tape recorder, turntable or FM tuner.

I was thinking in terms of DTS, DD, L7. Processing stereo into 6,7,9+ channels.

In any case, I don't much like any autoEQ. Which is why I use mostly my P7.

Yup, not bad at all. In fact years back my Proceed Amp3 had the same thing happen. Must be somewhat common for amps after they run off and on for several years if not more.

I have looked at the p5 - and i think that might be the better option for me but I do want to future proof incase I end up using another power amplifier or two for the whole surround sound eventually.

While the p7 is more expensive it doesnt currently (at least from what i can tell) have any additional features that the p5 has that i would be using for stereo playback. i could certainly be, and am often times, wrong though

I saw a couple deals on safe and sound today for b stock halo preamps...jc-2 b, p7 were the ones available today for decent discounts. i am mainly concerned with getting great 2 channel sound whether it be from the ud7007 on disc or digital from my NAS etc. passed through to the halo a21 as clean as possible. also i find it quite cumbersome and a bit irrational to use a beast of an avr like the sr7009 just to fire up some music that doesnt require anything else but a passthrough and sub eq/crossover/mgmt.

i do listen to some DSD and super audio cds but dont even have my surrounds hooked up yet as i ran into a speaker wire shortage running a 15 foot line to my front right speaker.

side note - i have no front left sound and the cable seemed fine and it worked last night - so going to try a replacement to ensure nothing is wrong other than a bad cable. waiting for some cables2go velocity 12 awg cables to arrive tomorrow that are 15 feet in length each. i have been shocked by the lack of options when it comes to longer cables with heavier gauge. seems counterintuitive to me, right?

i may try moving my rack closer to my television or even putting the a21 on a stand of sorts dead center of left and right speakers behind my tv....need to ensure proper ventilation though.

thoughts on using a jc-2? overkill? i do want to ensure i have a decent DAC as far as file playback options (i have many different formats and the only one i cant currently playback with existing equipment is AIFF) at least that i know of. im sure there are higher bit rate / sample rate files though that my marantz duo cant handle.

Did you consider Emotiva UPC-200? It is minimalistic design, can also switch HDMI. Accordinng to reviews analogue section is pretty good. Good alternative to any Marantz preamp. They also have stereo preamp for very reasonable price. Designing preamps is not as challenging as power amps. It is a class A essentially.

i have actually....before i bought the parasound i almost went for a 2 channel emotiva. the reference preamp interest me bc it has dirac which would be a nice change up from audyssey...

once i decided on halo for the amp i figured it may be best to stay in brand but definitely open to the idea of emotiva. also looking at a ayre acoustics too

I started with Toccata from Brain Salad Surgery. It is a 24x96 5.1 surround, 2014 remix flac (from Deluxe collection DVD-A). It was the first time when my jaw dropped since I bought A23. I heard Toccata probably hundred times over last 40 years. I also heard it on Marantz not so long ago with everything else (source, speakers) being the same and at such a volume (have to listen loud otherwise does not make sense) it never sounded so clean and precise, sonically correct and real life like (if you can say that about electronic music, well if you ever heard high quality sound equipment at the concert you know what I am talking about). A23 never got strained and was not as mushy (at that volume) as Marantz. It followed by Still...you turn me on from the same flac - I rediscovered this ballad to say the least. I did not want to move to Karn Evil since it was too late but moved to Grand Funk's Closer To Home, which starts with a heavy Good Man's Brother, knowing that it cannot be as good as BSS since Grand Funk's early albums never were high quality studio recordings. But they were authentic, iconic live quality albums recorded from the first try with no further processing in other words as is. It is a higher resolution 32x192 stereo rip from LP. Not only it was as clear as ELP remix (what I would never expect but boy was I wrong!) but also sounded like surround music. I even went back to surround speaker to check them but of course they were silent. I do not know how Parasound managed to make GFR to sound three dimensional but it did. When I play Grand Funk the whole house is shaking because of Mel Schacher's thunderous bass guitar and my wife gets nuts so I had to end session there and plan to continue tomorrow. I have the impression that I have to relisten all my record again. I am dying to hear Karn Evil in 5.1 tomorrow first. It is a long 20 min piece but it worth all of them.
I remember the first few Grand Funk albums and yes, they were highly distorted.

JC2 BP, P5 or P7

i think i am going to pull the trigger on one of these in the next day or so and wanted to solicit some advice from anyone who is familiar with these models and what the major (and/or minor) differences are between them. THe jc2 is older, but for two channel audio sounds like the cleanest option. The P5 and P7 are also attractive and price point looks really good for the p7.

my main goal is to be able to eliminate my sr7009 from the chain if you will or only use it as a DAC if i have to for music playback. I have two subs that I want to incorporate in this two channel playback scenario but not necessarily with the sub eq (i think the gain controls on the preamp would suffice)

I am trying for multichannel sound without having to navigate my clunky sr7009 menu and deal with hmdi BS. i am beginning to loathe this connection for audio as it is more complicated UMHO than it is beneficial. i am talking music only remind you

what i am seeking is something i can pair up with my marantz ud7007 and the A21 for music playback and not have to turn on my TV to adjust the settings, etc. does that make sense?

thanks in advance!

Their sound had psycho-underground feeling. I first did not like Grand Funk's first album (On Time) thought it was too primitive and flat after glorious British bands like Cream and etc. But got hooked up within few days. They had primeval appeal like e.g. religion which cannot be analyzed and explained. British band were turning rock into art and what Grand Funk did it come with new new fresh approach of underground garage band, like bunch of anti-mainstream revolutionaries who were ready to take on the world. The Times square billboard with three defiant faces http://rock-musicland.com/gfr/fotos/...mes-square.jpg challenging old order just further cemented this image in my mind. They become a cult group (still today with devoted base of fans). Later they become commercial so image was destroyed (after Terry Knight was kicked out). But the sound reflects it and I like those first albums including Phoenix and that natural live underground sound. First Black Sabbath albums had the similar qualities and SQ was not good either (have almost all of BS, most on SACD). Needless to say mainstream critics (like RS) hated both bands.

First stereo setup with Parasound!

Hello,
Came across this thread a little late.
Setup my system last year with the following specs.
I am loving it!

Parasound P5 Preamplifier
Parasound A23 Amplifier
Monitor Audio Silver 8 floor standing speakers
Marantz CD5004 CD Player
AudioQuest FLX14/4 CL3 Speaker Cable
Straight Wire Digital D Coaxial Digital Cable -> CD Player to preamp
AudioQuest Cinnamon Optical Cable -> AppleTV to preamp
AudioQuest Red River 1m XLR Cable -> preamp to amp

Question to the experts.
90% of the time I am streaming lossless from iTunes to the AppleTV connected to this setup. Rest of the time using the CD player.
Would it sound better if I hooked up a laptop to the P5 using USB instead, bypassing the AppleTV?

I also hooked up a old Klipsch Energy sub that I had lying around and it seems to sound better. I don't want to believe it does, but it seems to. Am I imagining things?

Tim, I just bought the JC2 BP and the A21, and they are a fantastic combo. Make sure to connect them with balanced cables.

Bill - I found a JC2 BP b-stock for 3295 and I am in the process of ordering but still time to cancel...I would definitely be using balanced connections - i assume XLR cables of a fairly short length would be right.

What do you like about the jc2 bp? did you compare before buying to any other parasound pre amps from the halo line? p7 seemed like too much overlap with my avr and p5 seemed like the right choice, but given it has more controls etc and the reviews i read about teh jc-2 being one of the cleanest preamps out there i thought i would keep the avr for surround duties and use the bypass when needed while using the jc-2 for stereo music playback and that has more appeal or value given my current setup.

i cranked up the A21 today after rewiring and moving my front left and rights (cm10s) close together (they were about 9 feet apart and now are about 6). There was a moment while in pure direct mode on my avr playing a super audio cd of dire straights brothers in arms with my speakers almost flat with barely any toe in at all when my jaw dropped, the hair stood up on the back of my neck and I said "wow". mind you i was alone in my basement and I didnt know I actually said wow out loud until after i had....and I am not just blowing smoke here, perhaps there was some speaker position movement etc that could have improved the sound over my sr7009 playing the cm10s alone but this was like nothing I have ever heard before. Money for Nothing is the song I use when trying to grade my sound as i find that no system i have heard yet (and i think the song is mixed this way anyhow) can really make that electric guitar lick the way I personally think it should be played...loud as F***. or more appropriately i think because the guitar playback is probably around an awkward frequency that isnt bass or maybe even mid bass so it is really hard to get the punch in the face sound that song needs. again my opinion only.

cant wait to incorporate the subs too and see how that changes things - probably crossover around 60 but i wish i had more options like 50 or 70 that the marantz doesn't allow for.

dependingo n how that sounds and wife approval factor pending my next experiment is going to try using line levels to get stereo subs going from my svs sb 2000s.

anyway - let me know your thoughts on the preamp question or anyone else for that matter and I appreciate the help and feedback as always!

I finally tried out direct connection from OPPO-105 to A23. Let me remind you that was using SR6005 as a preamp and DefTech Mythos STSs as a front towers. First I listened to Grover Washington Prime Cuts over SR6005. Then I switched RCA speaker cables to OPPO stereo output and setup OPPO volume to about 64. Boy did my jaw dropped again? The SQ become kind of three dimensional compared with using Marantz as a preamp. I again went back to surround speakers to check if Prime Cuts actually were multichannel after all, if I get confused - nope, no sound coming out of Gems, I am okay - it is still stereo. I finally realized that sound is less harsh and more transparent or scene is deeper whatever you prefer. I tried out other music also - everything sounded fantastic. Then I switched back to Marantz preamp outs - yes it become tiresome to listen, even though I found this sound mind blowing just few days ago when switched from Marantz amps to A23. I start thinking how it would sound if I bought A21.

Next I compared direct from OPPO via XLRs vs via RCAs. I can certainly say that RCA sounded better and the reason was IMO that I have to lower OPPOs volume further to 30-40s vs 50-60s for RCA.

Anyway, I switched between OPPO direct to SR6005 and back few more times (not easy considering how tight RCA cables are) to be sure and decided to leave A23 connected directly to OPPO and use Marantz only for surrounds. It means that I can change total volume via OPPO and surround/stereo ratio via Marantz - very convenient indeed. I start thinking about getting rid of SR6005. I will buy another stereo amp for surrounds (can go for smaller 100W or 125W Parasound New classic). Then I can route additional HDMI through OPPO-105 (it has two HDMI inputs). Other option to buy a new preamp. It might be Emotiva or something else.

But I am thinking if separate pre is any better or worse than OPPO direct? Does anyone has experience with that?

I did a similar test with my Marantz 8801, Oppo 105 and A21 and at the end of the day the analog inputs on the 8801 where transparent(in fact they were very good) enough to keep it in the chain

Did you go XLR or RCA?

parasound halo a23 ps cap size dimentions needed please!

Does anyone know the width, how tall and lead spacing/type of the Rubycon caps they have used in these newer year models? I was hoping to find some upgrade caps maybe Nichicon Gold Tune, Panasonic etc. I'm just trying to save the trouble of removing the top twice just to measure the dimensions. I was wanting to order them today if possible. Thanks!

Tim, for wire length, just order XLRs (I got mine from monoprice) based on how far the amp will be from the preamp or AVR (with some slack so they are not taught and so you can move them to gain access to the back of them for connections).
No, I did not do A/B comparisons with either the A21 or the JC2 versus other amps and preamps. I went with reviews. The JC2/JC2 BP is their flagship, and should outperform their other preamps. I guess the JC1 monoblocks would be their flagship power amps, but I couldn't justify the additional expense versus the A21 (and I don't have room in my family room for 2 massive amps). I have a pure 2-channel system, and don't need digital inputs into a preamp (I use the Oppo 105 for movies and CD/SACD listening, and am happy with its DAC), so I had no need of any features in the other Halo preamps not present in the JC2.
I have had the Oppo for about a year, but simultaneously upgraded my amp, preamp, and speakers just last week (to a pair of Sonus Faber Olympica III's). Thus I cannot differentiate between the advantages of upgrading the amp, preamp, or speakers (probably most of the benefit in AQ is from the speaker upgrade). All I can tell you is that, compared to my old system (Rotel amp and preamp, and Sonus Faber Grand Piano Home speakers), the bass is much better, and the music really fills up the room so that I feel immersed in a room full of music, rather than just listening to a pair of speakers set up in front of me. The new speakers are 4 ohm speakers, and my old Rotel amp was not rated for 4 ohms, which made me a little nervous (another reason for upgrading my amp/preamp in addition to my speakers). I am not going Oppo directly to the amp since I have other equipment requiring a preamp, and I prefer volume control from the preamp rather than the Oppo.

You cannot compare AV8801 with SR6005. SR6005 was actually downgrade, notch below the previous model. Both are not in the same league as OPPO-105 and A23, it is simply are out of place and therefore SR6005 needs to go. I would consider AV8802 but it has too much features for which I am not ready to pay. Emotiva is more minimalistic and straightforward. Good thing about OPPO is that it serves as a reference which any pre has to match or exceed or will go back to store.

Thanks for the feedback Bill. It is quite helpful as info gathered from dealers and reviews online are hard to trust depending on the source of course.

I just got off the phone with the reseller that carries b stock items from parasound and the jc2 bp i ordered (in silver to match my a21) was actually not a BP version and they said they will have a black jc2 bp in later this week but no silver with bp option yet. they are putting a call into parasound to double check before canceling my order.

now i am back to trying to decide if a the bp option is something i really need given i am going to be using my sr7009 for surround sound duties or if there is a logical way of hooking things up where i can use a jc 2 without bp for two channel with a21 and still utilize the a21 in my surround sound setup. Sounds like it would require physical switching each time...correct me if i am wrong anyone

The good thing at the time is I had Audioquest Columbia rca's and xlr's on hand as to compare both connection methods as well and in the end the 105 to the 8801 xlr assigned to the cd input using Pure direct gave very very close playback to the Oppo direct to the A21, of course I would prefer the Oppo directs sound but what little edge it had was out weighed by system simplicity. I'm hoping the new 8802 has the same or better analog inputs when I get the upgrade bug again.

Nice upgrade! I had a chance years back to try a HiFi Tunning Silverstar fuse in my A21 and was smitten by the performance jump! To dismiss any notion of placebo , I first removed the main (critical link fuse) ceramic fuse on the A21 cleaned the ends with Caig deoxit ( buffed to a shine) and couldn't believe it . I later cleaned all the internal fuses as well as I wasn't going to replace them all, after that test I was convinced! it cost nothing and the Silverstar I added later at the $65 I paid was the cheapest system performance jump I've had.

If at the least polish the main fuse and tell me if I'm nuts or not
