@thriftyaudio Glad to hear it! They really are crazy good outstanding amps. I think a lot of people ignore them because of the price or because they think of Schitt as some ‘discount-and-therefore-second-rate’ brand, but that is their loss. For power cords I have become a big fan of Ice Age Audio. Don Sachs recommended them to me originally and they really do make a difference. I’ve ended up converting all of my cable, i.e. power cords, enter connect, speaker cable to Ice Age wire. Worth considering if you’re in the market for other options.
Coda #8, Pass XA25, or Schiit Tyr to replace PS Audio M700
I recently upgraded my power amp from a Nakamichi PA7Aii to PS Audio M700 monoblocks. I honestly expected to flip the M700 pair quickly because I did not think they would be better than the PA7Aii. The M700s actually provide a wider and more detailed soundstage. I sold the Nak.
I listen (often passively) for several hours each day. I began to identify a 'shrill' on the high end. Since I had upgraded my DAC (DirectStream Mk1) I initially thought that could be it. I rotated three DACs through the system (DS, N130, and Eversolo DMP-A6). All of them had the shrill. I then put in an old NAD 7600 and the shrill went away along with a lot of the detail. Put the M700 back in and used the EQ from the DMP-A6 streamer to limit extreme high end. Ended up with a -1 Q starting at 19,500 Hz that solved the shrill, but also muddied the high end detail. I don't trust the EQ a lot and figure more is being impacted than the targeted range.
This led me to consider upgrading the M700 pair. I have a pair of Acoustat 1+1 speakers with low sensitivity efficiency (81 to 86 depending on who the source is) with a pair of Rythmik F12SE subs and an active crossover at 100 Hz controlled by the SPL Crossover. My budget is around $6K.
Looked at the Pass XA25. Not certain there is enough power there although a Pass representative encouraged my to try it. I was hoping to get two used and use them as mono blocks.
The Schiit Tyr has been on my short list for awhile (prior to buying the M700). The Schiit AI tool actually stated the Tyr was not a good match and suggested other Schiit amps. This seemed strange to me. I sent an email to Schiit seeking clarification, but have not heard back. I may go to there store in LA this week to talk to someone live.
The Coda #8 came up as an option as I was exploring. I looked at other Coda used products, but #8 seems to match up best. (Well, the #16 matched up best, but was more than double my budget). I will go take a look at it later this week. Not a mono block but could work.
I am essentially seeking the last 1-2% of the detail the Acoustats can provide. Any suggestions would be greatly appreciated.
One final note. I am not interested in tube power amps. I don't like the fussiness of tubes and the Acoustats seem to pick up the hum from tubes. I know it shouldn't happen with their sensitivity, but I notice it. It could be my prejudice, but please no tube suggestions.

@thriftyaudio , Now that you've learned your lesson, try and stay away from these Class D emperors with no clothes. Others in that list would be even some Class H crap with "shrill" SMPS, etc. If you don't see the big ol' transformer inside a power amp, run away. Your TYRs would benefit a lot more from a power conditioner with transient current support, i.e. conditioners that hold a reservoir of current and supply it when your slamming music demands it (in addition to all the filters/clean up, surge protection, ovp, etc safety that it provides). Hence, put your money into such a conditioner, instead of expensive power cables..Plugging amps straight into the wall doesn't give you such things. The wall will also kill all your expensive things when surges and other power anomalies hit your house. The power cable just needs to be triple shielded pretty good (or other forms of noise rejection deployed) so it doesn't leech any noise into your gear after it comes through the conditioner. So, look for something aftermarket better than the stock cord, but, don't throw all your money at it. Here are some power conditioners at a few different price points, based on your wallet's capability. - Audioquest Powerquest 707, 1300 dollars, 45 amps peak (reservoir on offer) - Audioquest Niagara 3000, 3900 dollars, 55 amps peak (reservoir on offer) - Audioquest Niagara 5000, 5900 dollars, 90 amps peak (reservoir on offer)
Hope that helps.
P.S. Any speaker that dips down to 0.5 ohms is a problematic speaker that needs to be sent back to its daddy. In the future, don't accept such speakers as some kind of competent design from any Speaker Daddy, send him back to the drawing board. I'll spare the choice words for different Speaker Daddies who release such speaker designs. Speakers should not be dipping anywhere under 3 ohms (that's the minimum you should tolerate).

Thanks for the words regarding power conditioners. I have a great one, but may need to add a second. Still need to confirm draw at peak volume. Regarding low ohm speakers. I have owned these speakers for 30 plus years (3rd owner). If you have never listened to true electrostatic speakers (not with a tweeter ribbon, or the abomination ones with a built in 15" driver) then you are truly missing out. The really good electrostatic speakers that I have had the opportunity to listen to have all been hard to drive. I suspect it is because of the variable ohm draw. Some speakers are just worth the extra effort to support their fantastic tone, speed, and presentation. The Tyr seem to be able to do it. I am certain the more powerful Pass Amps would do the same. The Nakamichi (Pass Stasis design) had no issue with the ohm draw. Definitely need to avoid class D with these speakers. THANKS! |

@deep_333 @sid-hoff-frenchman @erik_squires The Shrill went, but so did the Tyr. Blew a fuse at 82 db from three meters away on day two. The Tyr were very easy to listen to with decent instrument separation and a better stage than the M700. Replaced the fuse and listened at lower levels for a few days. Reached out the Schiit Audio six times by email without a response. Spoke with their guy at the retail location north of LA and asked him to have someone call or email me. He said he would pass my information along, but I have not received a response. I wanted to find out if a different pair of amps from Schiit would do what I want. Since they won't respond to my requests I can only do one thing. The Tyr are being returned within the fifteen day return window and I am moving on. Just purchased a used Pass Labs XA25. I have seen multiple reviews where it is suppose to be stable down to 0.5 Ohm. I am concerned if it can fill my room. If not, then I will need to flip it for something else. Won't know till next weekend. I really hope the XA25 works. If not, then I may have to up my budget.
