That's cool that the XPA-1 can be switched from class A/B to A. When we did our blind amp comparison GTG at my place I think we had almost every class of amp there is (multiples of some classes) but we did not have a class A.

With immediate switching and the volumes matched to within 0.1 to 0.2 db's we couldn't tell a difference between any of the amps. Ha, well at first we thought we could but we didn't realize Audyssey was switching itself on on the Denon AVR we were using. The differences were massive so we should have known..

Anyway, after that experience all that matters to me when it comes to amps is #1 power and #2 dsp options.

Back to my original point though, we did not have a class A amp so I'm open to the possibility that my ears might prefer a class A amp. I'll have to try one out someday.

I wonder how many watts in class A that amp puts out and if it's significant enough to gain any insight with the 215's. Now with the 212's that's a different story. It does, however, provide enough power in A/B for the 215's.

Did you guys have anything Class G/H? Class G/H probably makes the most sense.

All I can tell you is that the A51 gives plenty of power to 212s.
Also, nobody in this forum has really corroborated my preference of a high bias class A amp over a class D amp on JTRs.
In fact, there have been a number of 215 owners who felt that a pro high power amp was really beneficial on their 215s.

All that said, I liked the A51 with the 212s quite a bit more than the NC400s, even after room EQ.

I also liked the 212s MUCH more after fine tuning with Dirac. In fact, Dirac made a bigger improvement than the amp.

Anyway, to describe the difference more...
JTRs put out flat treble.
If the treble is harsh, it can be irritating if you don't roll it off.
If the treble is smooth, the treble isn't irritating...just clear and live sounding.
That was the A51 vs the NC400 to me, even after room correction to the same target curve, which normally made all amps sound the same.

A class D with a higher switching frequency than the NC400s might be able to sound identical to the class ABs on JTRs.

If I were to start from scratch with 215s, I think I would try Emotiva XPA-1s & an XMC-1. Emotiva has their summer sale going on (on top of those club discounts). The XPA-1 has lots of power and is high bias class AB. It may not sound exactly like the A51s, but I bet it would after some Dirac magic. Also, no fans!

https://emotiva.com/products/amplifiers/xpa-1

The XPRs are switching amps, so following these theories, XPAs would be preferable.
Thanks for the clarification and further details. I used to own XPA-1's and XPR-1's, I somewhat recently sold the XPR-1's and kept my XPR-5 which I am still using. Really interesting on the Dirac, how are you getting your Dirac?

I have a question for you all around amps (Yes Im still trying to decide).
If I get a 2 channel amp can I run 1 215 (4 ohm) and 1 S8 (8 ohm) on separate channels w/o issue?

My thought was if I could do this I can end up with essentially monoblock when using the setup for 2 channel and keep the load lower for TH by running only 1 215 per amp.

Also Im curious - for the 215 owners - how much power are you running with?

Thanks for any insight anyone can provide.

The XPA-1 actually switches between high bias class AB and low bias class AB. High bias class AB is much better than a "true" class A amp.

I have no idea whether this was an advantage of the class A (in high bias AB) or a deficiency with the NC400s. I was sure I wasn't imagining the difference, although it wasn't blind.

The PC version (along with JRiver). You can run the trial for free.

Should be fine as long as the amp is rated for 4 ohms.

I'm running each of my 215's with a crown xls 1500 in bridged mode which provides 1550 watts in a 4ohm load

What amp(s) do you have and what DSP are you using?

My understanding is that class G/H with low switching frequencies still require a brick wall analog filter, kind of like DACs on the 1st gen CD players.

To use more gentle filters, you need a higher switching frequency, which starts to compromise the efficiency gains of class D/G/H/T.

In theory, my 212's are running mostly in class A.
In practice, the audibility of this stuff is debatable, so skepticism is justified, but I just know I like my 212s with the A51.

I was running the Sunfire TGA 700 (about 600w/ ch 4 ohm) for the 212's which is class H I believe. I now use the Lab Gruppen10k for LCR (about 2100 watts / ch). Not sure of the switching freq on the LG but I prefer it to the Sunfire because of max power. They sound identical right up to the point where the sunfire starts to audibly clip (already very loud). At that point the LG still delivers another 6-8dB of clean SPL in my room. And yes with the OS's you can keep up with 212' running flat out! If it were the 215 even more important to get the power right if you like to crank it.

^on the Dirac my experience sounds very similar to Rcohen. Incredible improvement to the subjective sound (seems better louder with less fatigue) and much better measured impulse response. Best move I have made in HT equipment besides the JTR's was getting Dirac.

Taking the 212s to clipping at 600w must be insanely loud!

There are three ways I found that Dirac helps with listening fatigue.

1) You can dial in the exact tonal balance that sounds best with speakers, room, and your taste. Adjusting sub levels, loudness, and tone controls that you get in many amps can sorta get you into the ballpark, but it's not enough control.

2) Spikes in the frequency response can cause fatigue, and of course those are corrected.

3) Enhancing the clarity (dialog clarity and impulse response) reduces the mental effort to hear through those kinds of problems. Room treatment also helps with this, but the combination of room treatment & Dirac is idea.

As an aside, #3 is one thing I hate about dipole surround speakers. It's a neat-o effect, but I find it a bit mentally fatiguing to listen to, compared to monopoles. Same goes for Audyssey DSX.

Other issue though is the pro amps do offer EXTREME watts and on an inexpensive watt per dollar basis to run the 15" woofers do great levels so where do you trade off at. Wondering if the A51 had enough juice to drive the 15's to great levels of bass.
No way. As others have discussed, the 215's need a substantial amount more if you are "Cranking it" every weekend.

This is even more absurd (no offense). If you guys are wanting to shell that type of dough for monoblocks, look no further than the dsonic or wyred for sound options. Even their 7 channel offerings are single chassis, but 7 standalone monoblocks. They build out their subs as "Modules" for each channel so they can be entirely replaced or upgraded if needed. a 3 channel Dsonic for a front stage is ample power for even the reference enthusiast. Takes up a ton less room as well.

+1

I was close to pulling the trigger on a custom D-Sonic M3-4500-3 for the LCR 215RT's. I decided to hold off due to not being the least bit unhappy with the iNUKE NU4-6000 at a small fraction of the cost of the D-Sonic. I rarely listen at reference these days and I find -5 to -8 ref all I need for movies and concert blurays.

Hello all!

I'm still trying to decide what to do for amps, and was hoping for some input/advice/thoughts. Here are are few idea's I'm mulling over.
My intent it to have dedicated circuits put in for the amps.
Equipment will be in a separate room from my viewing/listening area.
Standard speaker wire will be easier to deal with in my already finished room than speakon cables.
I have an INUKE at the moment powering the 215's but there is an audible hiss at 2-3 ft from the speaker, this INUKE will eventually be used for Subs. (I suppose I'm being picky here maybe too picky as using all INUKES could save $1k)
I want to hit crazy levels of SPL awesomeness, and still have some headroom left - and make sure I do this right the 1st time.
Also trying to keep the price below $4k.

Questions:
I see some amps have input level switching from 1.2v to 3.9v, some don't - how important is this? (Running from an Onkyo 3007 AVR)
How important is the HPF that Jeff recommends? (I see people here running w/o it, but Im running full range atm)
If the HPF is very important what can I use as a HPF on the RT's if the amp doesn't have one? (Mini-DSP?)
Anyone know any place that I could get a good deal on the pro audio stuff?
Is all this way overkill for a 6500 Cubic FT room, which will be fairly well treated when finished? Could I get away with spending less w/o loosing much performance?
Any other suggested options I should look at?
Any other things I should be considering in making my choice?

All Power ratings below are RMS. And any opinions on
Option 1:
  • 2x Crest 4000 - 1350 Watts @ 4 ohm /800 Watts @ 8 ohms (215RT on one amp and 215RT + RM on the other) - $1000 per amp
  • 2x Crest 2800 - 595 Watts @ 8 ohms (remaining 2 S8's) - $800
  • Pros: Separate amps (if one fails Im only out 2 channels), Lower THD than most other options, Known to sound good (Thanks David!)
  • Cons: No HPF, No Limiter, No DSP, no 12v switch, Speakon connectors
  • Total Cost:$3600 + shipping

Option 2:
  • 2x Crown XTi 4002 - 1200 Watts @ 4 ohm /650 Watts @ 8 ohms (215RT on one amp and 215RT + RM on the other) - $920 per amp
  • 2x Crown XTi 2002 - 595 Watts @ 8 ohms - $660
  • Pros: Separate amps (if one fails Im only out 2 channels), DSP, HPF, Limiter, Can use speakon or standard speaker wire
  • Cons: no 12v switch, Higher THD (.5)
  • Total Cost:$3160 + shipping

Option 3:
  • 1x QSC PLD 4.5 - 1250 Watts @ 4 ohms (4 channel) - $2000
  • 1x QSC PLD 4.3 - 625 Watts @ 8 ohms (4 channel) - $1500
  • Pros: DSP, HPF, Limiter
  • Cons: no 12v switch, Higher THD, Speakon connectors
  • Total Cost:$3500 + shipping

Option 4:
  • DSonic 7 channel - 1500 Watts x 2 channels, 800 Watts x 1 channel, 400 Watts x 4 channels (at 8 Ohm) - $4000
  • Pros: Fully Balanced (future use), best THD, 12v trigger, standard speaker cables
  • Cons: No DSP, No HPF, If unit fails Im out all channels while repair happens.
  • Total Cost:$4000 + shipping

Option 5:
  • DSonic 7 channel - 800 Watts x 3 channel (1200+ Watts at 4 Ohms), 400 Watts x 4 channels (at 8 Ohm) - $3500
  • Pros: Fully Balanced (future use), best THD, 12v trigger, standard speaker cables
  • Cons: No DSP, No HPF, If unit fails I'm out all channels while repair happens.
  • Total Cost:$3500 + shipping

Thanks everyone for any advice given here! I just wish there was one amp to rule them all at a non bank breaking price!

Go with option 5 and don't look back. If you want DSP get a Mini-dsp. D-Sonic makes Awesome amps and Dennis is a pleasure to work with. I've had mine for over 3 years and It's the best piece of audio equipment I've purchased. I went through a lot of amps to get to D-Sonic. Crown has always been my favorite value amp. I still have a xls 2000 for mobility and outside duty.

Option 4 is great too but I don't believe you will be able to hear any audible differences. I'd actually bet none could with the 2125RT. Nate uses the 7 x 500/1000 wpc D-Sonic to power his. If a unit fails Dennis will mail you the individual module to change out yourself.

I feel like D-Sonic is the one amp that rules in its price range.

Not sure what they are saying, but apparently Jeff's market has gone international.
Ha! That was interesting reading through that. A lot lost in translation obviously... did you see that one of them linked two of your youtube videos? In one of his posts he was making the point that you don't need much power for the 212 "headphones". The word speakers translated to headphones for some reason...

You could tell there is some confusion about the MSRP price and the direct price. Looks like they figured it out:

"In the United States always going to be one of them two prices is the price is the MSRP and the candidate from the factory and is usually high and free of cuts .. the other is the actual price or the reduced price .. You can ignore the MSRP price in this case."

"For the beauty of the sound these speakers is characterized by being dynamic and ability to play audio to the level of the reference with less effort. Another advantage is not their need for Ombilvair. Receiver will be respected more than enough to employ .. I intend them to development in the future, God willing, my room."


This is cracking me up for some reason, I love the line "receiver will be respected more than enough to employ."

I have too much time on my hands...

This is even more absurd (no offense). If you guys are wanting to shell that type of dough for monoblocks, look no further than the dsonic or wyred for sound options. Even their 7 channel offerings are single chassis, but 7 standalone monoblocks. They build out their subs as "Modules" for each channel so they can be entirely replaced or upgraded if needed. a 3 channel Dsonic for a front stage is ample power for even the reference enthusiast. Takes up a ton less room as well.
No offense taken but I'm not looking at some expensive class A monoblock....it was just a reply. I'm running Crowns putting 1550 watts to each of my 215's and they are not expensive at all as everyone here knows. If I ever move away from them I would consider the dsonics as lots of guys here speak fondly of them. But at the moment, I'm doing well with the Crowns.

Oddly enough I noticed a screen name on there by the name WereWolf. He post's on AVS.

On another note, I mentioned this before that I found videos of all our GTG's on a Russian website. Like you I googled something related and there we all were in Russian! Creepy.

I'm still trying to decide what to do for amps, and was hoping for some input/advice/thoughts. Here are are few idea's I'm mulling over.
My intent it to have dedicated circuits put in for the amps.
Equipment will be in a separate room from my viewing/listening area.
Standard speaker wire will be easier to deal with in my already finished room than speakon cables.
I have an INUKE at the moment powering the 215's but there is an audible hiss at 2-3 ft from the speaker, this INUKE will eventually be used for Subs. (I suppose I'm being picky here maybe too picky as using all INUKES could save $1k)
I want to hit crazy levels of SPL awesomeness, and still have some headroom left - and make sure I do this right the 1st time.
Also trying to keep the price below $4k.

Questions:
I see some amps have input level switching from 1.2v to 3.9v, some don't - how important is this? (Running from an Onkyo 3007 AVR)
How important is the HPF that Jeff recommends? (I see people here running w/o it, but Im running full range atm)
If the HPF is very important what can I use as a HPF on the RT's if the amp doesn't have one? (Mini-DSP?)
Anyone know any place that I could get a good deal on the pro audio stuff?
Is all this way overkill for a 6500 Cubic FT room, which will be fairly well treated when finished? Could I get away with spending less w/o loosing much performance?
Any other suggested options I should look at?
Any other things I should be considering in making my choice?

All Power ratings below are RMS. And any opinions on

Option 1:
  • 2x Crest 4000 - 1350 Watts @ 4 ohm /800 Watts @ 8 ohms (215RT on one amp and 215RT + RM on the other) - $1000 per amp
  • 2x Crest 2800 - 595 Watts @ 8 ohms (remaining 2 S8's) - $800
  • Pros: Separate amps (if one fails Im only out 2 channels), Lower THD than most other options, Known to sound good (Thanks David!)
  • Cons: No HPF, No Limiter, No DSP, no 12v switch, Speakon connectors
  • Total Cost:$3600 + shipping

Option 2:
  • 2x Crown XTi 4002 - 1200 Watts @ 4 ohm /650 Watts @ 8 ohms (215RT on one amp and 215RT + RM on the other) - $920 per amp
  • 2x Crown XTi 2002 - 595 Watts @ 8 ohms - $660
  • Pros: Separate amps (if one fails Im only out 2 channels), DSP, HPF, Limiter, Can use speakon or standard speaker wire
  • Cons: no 12v switch, Higher THD (.5)
  • Total Cost:$3160 + shipping

Option 3:
  • 1x QSC PLD 4.5 - 1250 Watts @ 4 ohms (4 channel) - $2000
  • 1x QSC PLD 4.3 - 625 Watts @ 8 ohms (4 channel) - $1500
  • Pros: DSP, HPF, Limiter
  • Cons: no 12v switch, Higher THD, Speakon connectors
  • Total Cost:$3500 + shipping

Option 4:
  • DSonic 7 channel - 1500 Watts x 2 channels, 800 Watts x 1 channel, 400 Watts x 4 channels (at 8 Ohm) - $4000
  • Pros: Fully Balanced (future use), best THD, 12v trigger, standard speaker cables
  • Cons: No DSP, No HPF, If unit fails Im out all channels while repair happens.
  • Total Cost:$4000 + shipping

Option 5:
  • DSonic 7 channel - 800 Watts x 3 channel (1200+ Watts at 4 Ohms), 400 Watts x 4 channels (at 8 Ohm) - $3500
  • Pros: Fully Balanced (future use), best THD, 12v trigger, standard speaker cables
  • Cons: No DSP, No HPF, If unit fails I'm out all channels while repair happens.
  • Total Cost:$3500 + shipping
Thanks everyone for any advice given here! I just wish there was one amp to rule them all at a non bank breaking price!
Everyone here likes the dsonics amps...I have no experience with them but if I move away from my Crown XLS 1500's I would strongly consider them. I can't disagree with Country's advice to go option 5.


As I've said before I have 5 Crown's at a total cost of $1798 which is cheaper than any of your options. If you're just looking to power the 3 215's then you could get 3 Crown's at less than 1k. They are $299.99 right now at Crutchfield and who knows you might find them cheaper. Or you could add more iNukes, since you already have one as a even cheaper option.

Crown makes excellent quality amps and their specs are not to exaggerated. My xls 2000 sounds identical to the D-Sonic. If I was not using DS I would have Crown xls or xti series all around.


Why I like the DS
Convenience
size = 7 channel amp @ 55lbs,
efficiency @ at ~85%
Does not heat up
No fans
It just sets there doing what is supposed to while not drawing any attention
I have never knowingly clipped this amp
Dennis now uses Pascal amp modules in the M3 amps
The multi channel amps are true mono-blocks sharing a single power source
