Amp for Acoustic Zen Crescendo 2 ?

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! 

Kenny you can use pretty much any decent damping material with adhesive backing. Auto parts stores have all kinds like the brand Dynamat.

Soundcoat sells a nice product that you can buy from Sonic Craft. Here is a link.

It is very expensive however. I needed a bunch to use in my server, amp, audio rack, and speakers. I used the stuff below, and while technically it may not meet the definition of constrained layer damping, it worked well for me. It is used by the military to damp vechiles etc... The price is right for the huge quantity of it. I used two or three layers depending on placement. Careful as it is conductive!
