Anyone listen to Zu Audio's Definition Mk3?

Spirit,
It seems you have built a truly excellent system,congratulations! Without question you`ll get numerous opinions regarding which power amp is better for your system.The ASR does seem to be overkill power(on paper anyway) yet I don`t doubt glory,agear or others who prefer it(why should I?). The issue is what type of sound moves you and connects you to the music you enjoy.

Depending on your ears and taste I could see any of the 3 choices working out great for you.For me given my preferences and priorities I`d buy the Audion amp in a heartbeat.But as we all know it purely personal choice as opposed to some infailiable objective rule book. Hey, just buy which ever one sounds best to your ears when the time comes. It is pointless to argue about which amp is better in absolute terms, audio is the epitome of a subjective endeavor.
Regards,

I asked the Zu boys the same question on to much power. With a smile I got the answer of the more power the merrier. ASR power is a great match with the Def speakers.

Make sure you use clean power with such an amp like the Purepower unit. Plug it into the wall and suck on an egg.

Hi Glory, don't believe in conditioning, convinced it can suck the dynamics out of a system (poss. restiction to power amp peak current). Much more convinced by balanced power, aiming for a 9kV unit with enough headroom for any amp out there.
The consensus on ASR seems to be that it is the champ on transparency, soundstaging and dynamics, but leaves many listeners with a cool, detached presentation.
Will be fascinated to investigate this further. 213Cobra no doubt will feel SET amps fill in the emotional quotient in presentation.

Spirit, three tube-o-phile Zu owners converted, and coolness and sterility has not been the consensus. Source (you have a good one) and cabling matter.

The OTL route makes some sense too. In addition to the Dave Berning Z-OTL, Atmasphere is also worth looking at....

Spirit,

They same had been said about the Dart amp or any other SS amp. It you are not willing to hook up the ASR to the right wire/components then stay away from it. But if you have the time and find a used unit you can steal one from a owner who is wanting to try the latest/greatest amp.

A cool and detached presentation is not what I or 6 other owners are hearing. 5 of the owners have tubed Dac's, 3 AMR/2 Lampizator and one SS. The 7th one I have no info on his source. Three of us run Zu Def speakers with the Emitter 1.

Read the PF review of the Emitter when the reviewer found the right hook up wire for the ASR and what he said about it.

There are some who have heard Zu speakers that have said they were left with a HF sound. You and I know different when hooked up to the right gear.

I hear Dad running around the corner with his SET thoughts LOL. Yes they do sound good on Zu speakers. Will wait for your thoughts on amp selection with anticipation.

You are not going to use the stock Footers for your new Def4 are you?

The Purepower is not a PC and doesn't limit dynamics.
