Hello everyone, I'm happy to report that my b-stock 2100 preamp and 275 v2 amp arrived safely from Audio Advisor today...looks and works like new. Tim's the hookup if anyone is shopping.

They sure do. That is a Kenwood TS-870SAT, Amateur Radio Transceiver. And the little device sitting on top of it is a set of paddles for sending Morse Code (CW). I've worked the world on that beast

I just added an A23 to power my L/R (KEF R900) with surrounds and center powered by a NAD T777. The output increase from the T777 isn't that much but since connecting everything this morning I do discern some additional headroom relative to where the volume control numbers were prior. So far really like the sound. I was able to purchase from a local dealer in the Seattle area and trade in a pair of Def Tech SM350s at the same time!

Can't think of a better way to spend a Saturday Afternoon than breaking in some new gear:

Is the bottle opener on the new gear list? ;-)

Awesome stuff! Keep it coming.

Someone needs to make a high end audiophile bottle opener that does not transmit vibrations to the floor. Make it $5000.




Anyways,


Guys, what is the difference between the 5125 and 5125 V2? These are 5 channel 125w. I can't seem to find the difference.

Parasound Owners Thread

My A21 was humming at the amp so I opened up the outlet at the wall and realized that I had the ground from the adjacent line tied to my dedicated AV circuits ground. Fixed that up and plugged everything into the dedicated line. Much better, no more transformer hum. Still having a bit of hiss and crackle in the speakers but really low now, I'm going to see if I can fix that as well.

I also pulled the Monster power center and installed a PS Audio P5 power regenerator. That thing really added a bigger soundstage, tighter bass and more air to the music. I was on the fence due to cost but the difference is more than subtle.

Any ideas on dealing with the minor hiss and pop, I think it's inside the 8802 because it gets lower when I go from stereo to pure but I'm not sure.

Do you have a cable box in the chain and hooked up into the 8802? Cable boxes are big contributors to hum and hiss.

I do. I also have a jensen filter that Im going to put back in. It made no difference with the screwy ground issues maybe now it will help.

I'm running a Halo Integrated with a Thorens Turntable through the built in phono stage. Recently, I upgraded from an Ortofon 2M Bronze moving magnet cartridge to a Dynavector 20x2L moving coil. This is my first moving coil cartridge after using several moving magnet cartridges.

While the audio quality is really great, I find that I have to increase the volume gain significantly higher than I did with the moving magnet cartridge. Sometimes, I am over 1/2 volume...never saw those levels with the Ortofon.

The HINT runs very cool under these circumstances, so I'm not really concerned about stressing the amp. Parasound also reassured me that it is fine operating this way.

I do wonder, though, if I should be considering a separate phono stage to improve performance? Or, is this the nature of moving coil cartridges?

The other thing I noticed was that when the volume on the HINT was up past half, I do hear a slight hiss from my speakers at that volume when set to Phono on the amp but not playing music. This hiss was not audible when playing music at this level, though. Does this seem normal?

Thanks to anyone who considers my questions!

You're probably fine with what you have but perhaps a step up transformer would make things better?

Did some research, and decided to go with a Dynavector P75 MKIII phono stage. I guess I'm a bit disappointed that I am bailing on the HINT's built in stage, but I don't think I can live with it performing the way it does currently with the Dynavector 20x2L. Feel like im leaving something on the table.

Rather than experiment with a SUT, I decided to go with a unit that should be very compatible with my cartridge. Hope I made the right call!

Hey Parasounders,
I own the 1000A and have good experience with the 5125 amplifiers.


I'm seriously thinking about moving to the Halo line for 2 reasons: I love the Parasound "sound" and they would look fantastic in my rack.




But.... am I going to hear a real world difference between my 1000A and let's say the Halo equivalent (A23)?
I'm thinking of getting rid of my 1000A and getting a A52 and A23 for my 7 channels.

You might want to consider an A31 and two A23s. I prefer to keep amps close to speakers, so I use three JC 1 monoblocks for LCR and A23s for side and rear surrounds.

I have the exact same A21, A51 PARASOUND Halo power amps. I also have a Halo A23 powering a pair of Definitime Technology BVP front height ambient speakers.

The A23 is an outstanding power amp and the perfect solution for driving my front height speakers and would be ideal for driving your Atmos ceiling speakers. It has been a seamless addition to my system and the A23 maintains the exact same sound and soundstage as my A21 and A51 amps.

To be honest, I purchased all three PARASOUND power amps simultaneously; the A23 was my first and only choice to power my height ambient speakers.

If you are interested in maintaining an outstanding, COHESIVE sound throughout your ENTIRE home theater system go for it. Some say the A23 is "overkill", but from first hand experience I can tell you that the PARASOUND Halo A23 fits, sounds great and was worth every penny.

How warm do the A23s run? I am also running A21/51 amps for my mains and an older 2205A for Atmos. I may consider replacing the 2205A to a pair of A23s to keep all amps in the Halo line, but they like the 2205A would be located in an enclosed cabinet. Thanks in advance.

I had an A23 which I sold so i cant compare it directly but I recall that it used to get hotter than my A21 and A31. Neither if which get too hot.

I have an A23 that I am using to power a pair if KEF R900 - I haven't had it for too long (a few weeks) and have played a lot of music and watched movies, etc. and noticed it hasn't gotten very warm at all. I play it pretty loud but do have it siting on the top of the cabinet and not enclosed. Very happy with it so far!

My A23's run warmer than the A21, but not as warm as the A51.


You can still comfortably lay your hand on it, but your rack should be open, or at least ventilated. The A23's have their heat sinks inside the case, so they likely aren't as efficient at shedding heat as the bigger Halos with the "fins."


BTW, my A51 is for sale if anyone is interested. Just recently serviced by Parasound in San Francisco too (I'm fortunate to live within driving distance). Attached is a pic.

I have a pair of A 23s that I use for side and rear surround. They're mounted in a small cabinet with a few inches clearance all around. They get no more than warm to the touch, and less warm than my JC 1 monoblocks set to low bias.

Good evening, Gentlemen and Ladies.

Quick question. I'm now the proud owner of the A51. What a Beauty and Beast it is. I just tried to install it in my Sanus Rack but the heat sinks are too wide. Do I have to install it through the rear? I've yet to try that because it's so hard to wrestle this thing around, I don't want to waste my effort if it will also not fit that way. The Sanus rack, to my knowledge, which isn't extensive by any means, is a standard width rack.
Thank you.

Thanks. I did measure both. According to the specs provided by Parasound, the A51 is 17-1/4 wide by 20 deep by 7-5/8 high, or 4 rack units.

The A52, A21 and A23 (I have 2 A23's currently rack mounted without no problem) according to the specs are the same exact measurement width-wise, yet one look at the A23 and you can see it's considerably narrower.

I measured the A51 and it measures 17-1/4 as stated. I measured the width between the vertical bars that contain the holes in which the screws go and it's about 17-1/2, not very easy to measure.

I just tried again and if I tilt the amp it goes in one fin at a time. Perhaps with two people it will be doable. Otherwise it's just too heavy to chance.

The rack is the Sanus CRF 126. I tried linking to it but it doesn't work.

It says the shelves are 17-7/16 wide but they are not wide enough to sit the amp on. Not that I want to use a shelf, I don't.

So, is this or is this not a standard 19" wide rack? If measured wall to wall it is, but I don't know where that measurement is taken from.

The A23 runs a bit warmer than the A21. As someone else said nowhere near as warm as the A51. That said, all of my gear is located in a custom 4 TEIR VTI OPEN RACK.

http://www.vtimanufacturing.com/vti_product/blg404-audio-rack/

After months of research I went with the VTI BLGSB404-13 (and ordered an additional 9 inch rack) with smoked black glass shelves. It looks fabulous and goes great with either the silver (which we have) or black PARASOUND Halo amps. *I didn't use the black mesh "wire management" that was included with the rack

Each Halo power amp and my ONKYO PR-SC5508 Preamp has its own separate rack shelf and I intentionally designed it so that absolutely NOTHING IS STACKED ON TOP OF ANY OF THE POWER OR PRE AMPS. The result is all of my amps run cool to slightly warm even after 5 to 8 hours of strenuous use because there is a free flow of air surrounding all four sides and I chose higher shelf to provide "breathing room" above each of the power and pre amps as well. The ONKYO and the A23 have shorter height shelfs because they don't generate as much heat as the A51 & A21 and need less breathing room. This set up provides maximum ventilation. *The VTI rack was one of the best investments I made, worth every penny. The added benefit is that the VTI rack system is flexible and can be added to, or rearranged as additional rack space is needed.

*3 Important facts to consider: 1) Proper ventilation for electronic equipment like this is vitally important because excess heat destroys electronics equipment. 2) If you are going to enclose this gear in a closed cabinet it is essential that you also incorporate some sort of ventilation, fan/cooling management system into the cabinet to dissipate the heat. 3) Unlike the A21, A31, A51, the A23 DOES NOT HAVE EXTERNAL COOLING FINS designed to dissipate the heat generated by the power amp. So yes, the A23 does run warmer but it's not hot to the touch in our set up.

I hope this helps

After months of research I went with the VTI BLGSB404-13 (and ordered an additional 9 inch rack) with smoked black glass shelves. It looks fabulous and goes great with either the silver (which we have) or black PARASOUND Halo amps. *I didn't use the black mesh "wire management" that was included with the rack

Each Halo power amp and my ONKYO PR-SC5508 Preamp has its own separate rack shelf and I intentionally designed it so that absolutely NOTHING IS STACKED ON TOP OF ANY OF THE POWER OR PRE AMPS. The result is all of my amps run cool to slightly warm even after 5 to 8 hours of strenuous use because there is a free flow of air surrounding all four sides and I chose higher shelf to provide "breathing room" above each of the power and pre amps as well. The ONKYO and the A23 have shorter height shelfs because they don't generate as much heat as the A51 & A21 and need less breathing room.

Yup! I'm using VTI as well, when searching 5 yrs ago it was and still is the one of the few racks that will accommodate the depth of my Halo A21 with a nice 6" of space on top for proper ventilation.It runs cool to just barley warm along with the rest of my gear
