Theta Enterprise or Ayre V1x with Vandy 5A

I have not tried the Ayre, but I do own a pair of Enterprises (which drive my Thiel CS3.6's). I had set off on an amp quest which I thought would end in the purchase of a high end Krell or Edge amplifier, when I had an opportunity to audition the Enterprises. What sold me on the Theta's was the incredible soundstage width and depth, the separation of multiple instruments, and what I consider to be a very musical midrange and top end (for SS amps, of course). The low end is not Krell-heavy, but it was every bit as good as an Edge NL-10, and again very accurate - upright bass sounds like upright bass, electric bass sounds like electric, etc. I know that Mike Fremer's review of the Enterprises was somewhat critical of certain aspects of the them, but if you really read his review, his main complaints seem to fall within the "tube vs SS" realm. All in all, I thought his review was quite favorable. What was also important for me (as I will be running these amps inside a cabinet until my kids are a bit older), the Theta's do not run hot at all.

I have only heard good things about the Ayre, so I would think that the V1x would also be a good route. But, for what it's worth, I am a very happy Enterprise owner (and the CS3.6's are not the easiest speaker to drive).

Thank you all so far for very informative responses.

I have owned both the Enterprises and the Citadels. The Enterprises are nice but to compare them to the Citadels there really isn't much of a comparsion there is nothing the Citadels cannot do, the highs are great the bass is so taut, transparent, soundstage is so large and deep-in another world i could go on and on a true high end amp.!!! The Ayre will not be in the same league with the Citadels. If u got the money get them!!! If not get the Enterprises which are quite good. Citadels are one of the top amps ever made all reviews rave about them and they are that good find a pair and try umm!!

Hi,
I agree with Rex on the cable point. I've used K-B cables and they're great...but I also noticed a softening of the midbass and a lessening of PRAT. Try other cables before you spend megabucks on another amp.
As for the amps, I suggest that you add another brand to your considerations. A new BEL 1001 Mk V will be as good or better than the Theta or Ayre for less money. Call Audio Concepts in Houston if you want a dealer opinion. Last I checked they carry all three brands. The one they use with the 5As in the high end room is the BEL.
Don't get me wrong, none of these amps are bad choices. But, I have BEL amps at home and have heard many others. There is simply no way to convince you without having you hear them. So if you decide to buy amps, try going to a dealer who can demo them on 5As for you.
Good luck!
Michael

Know way a Bel is better than a Citadel!
