Amp for Acoustic Zen Crescendo 2 ?


Hello all,
I have these speakers for 2 months now and want to move on to a tube amp of 50 - 60 wpc or so, or a SS amp that fits the bill..  My current amp is an Ayre V-5xe.  I'm looking for an amp to sweeten up the top end and has a midrange that does vocals full and articulate, even if that means colored.  The Ayre is a great amp but I think there is a better match out there.  I'll have to save up for used, under $5K.  I'm especially interested with what actual owners would say, as well as their system specifics, but all comments welcome.  Acoustics and speaker placement are fixed and substandard.  That's just the way it goes at our house.
I'm using a steel arm VPI TT with Ortofon Cadenza Bronze, ARC PH-7 and REF 3.  Thanks.

Bill,

Thank You for the info,the military surplus stuff looks like it would work just fine in most applications.Dynamat is the only one that I have ever used on driver baskets and inside chassis of components.


Kenny.
Kenny I like the Soundcoat product that Sonic Craft sells for the inside of electronics. Not conductive and works just great. Just to pricey for the bottom of Audio rack shelving and woofer baskets. 
Here are my typical listening sessions with one of my favorite Acoustic Guitarist, Julian Bream.

- How loudly do you listen when you go loud? Did you ever capture with a db meter?

Measurement taken on my Tablet ranging from 73-83 db at my listening position.

Wig

Thanks Wig. Very modest listening levels for sure. I am going to listen to Julian today. 
If you have reasonably normal hearing acuity and listen in a relatively quiet room, wig’s listening levels seem quite typical in my opinion. I’m assuming that this is C-weighted (as opposed to A-weighted) scale. Bill, are your listening levels typically in the 90 db and higher range?

Certainly we’re all different in regard to our comfortable and satisfying volume levels. Mine are in the same range of wig’s the majority of the time. Occasionally I’ll listen at higher levels but not for long periods of time. If someone has some degree of hearing deficiency I could understand the need to crank up the volume level to compensate.
Wig probably has such a high degree of resolution and transparency in his system that it provides much involvement without having to turn it up louder.

This has been my experience as my system has improved over the years. Nuances, inner detail and dynamic ebb and flow are apparent at lower listening volumes compared to prior systems I’ve owned.
