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.

Wig, I also run a single wire up the bass to the high frequencies with no jumpers. Simply strip some 5 inches of the Duelund wire and wrap around each post in a continuous run. No connectors needed for best sound. Now I liked the 16 gauge a lot, but found the 12 gauge had a tad more body and weight. The 12ga is a tad less lively than the 16 ga. For me that was a good thing.

Now the Western Electric 10 gauge is also,very, very special and the warmest of the three. It happens to be what I am using right now. Here is a link to the wire I am now using.

I did aother mod to my Crescendos. Ha! Pretty soon they need to be called another speaker! I used Soundcoat constrained layer damping to damp each of the woofer frame baskets. I like the result thus far.
Hello all,

Bill are you considering the 508ia for your system,If you get one let us know how you like it.

Wig,thank you for all the good info on the 508ia,I'm glad to hear that you are enjoying it.

Charles,

As I’ve often written, there’s no substitute for actually listening to an audio product.

I have always found it to be just priceless and really no better way than to try out different products in my own system,room,and music.

I received a text from my friend that has the 508ia and he said that they are going on vacation in 2 weeks and I could borrow his amp while they are gone but only if I promise him that I will not do any mods to it.Lol.When he comes back from vacation I will loan him my LTA gear for a weekend.

Grannyring,

I would now call your speakers the "Billcendos" 😁😁.

Can you provide a link to the soundcoat product that you used.

Hi Kenny. 

No I am not, but I wanted to know more facts for the poster. If the poster wants a tube amp it seems like a solid choice. I simply have my system on far too much to run a tube amp. My Lyngdorf unit is just spectacular with my mods and the simplicity is hard to adbandon.

 I owned a very special set of tube monoblock amps made and customized by Von Gaylord (Legend Triode) that competes with any tube amp costing up to $12,000 that I have heard. I have heard many.  I paired it with my Super Hot Rod version of the TRL Dude preamp and a superb Luxman DA06 dac.

The Lyngdorf simply gave up nothing and actually improved some areas.  Few know about it or will even try it, but I am the lucky one:)
No, it is going nowhere. Now I do have the ability to use it as a preamp, dac, and room correction unit with a separate amp if I choose. I have tried several amps with it, both tube and SS, but always come back to the Lyndorf on its own. It just draws me into the music more. 

I am am considering trying a First Watt amp and comparing just to see. Not sure it has enough power however. 40 watts into 4 ohms? My experience has been the AZ Crescendo can play with 30 watts, but plays better with over 100 watts. 
Kenny, mod that 508! Bypass those poor sounding binding posts! I know you have skills. Modifying that amp is not for the timid as I am sure you will find 700-1000 Vdc, not 375-500. Ouch!
