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.

Charles, my noise comment goes for all other system combinations I have experienced ranging from all tube to all SS and a mix of the two. Noise is a result of many things beyond a tube. I am not saying, did not say, the Lyngdorf is the latest and greatest. I am not saying, did not say, it is as good as the LM508. It is different and does some things better for sure. Cannot compare the two as the Lyndorf unit should be used on its own with no separate dac or preamp. It's greatness in found when utalizing all it does as a complete system. However, I am saying it represents what is coming - gives a taste of it. What is coming in the digital domain with all in one units will in fact render today’s tube and other non-tube gear a distant second. The Lyndorf unit is not some sort of holy grail unit in my opinion, but it does address areas that innovation will continue to refine and improve. Innovation, in this regard, will indeed be most positive for every flavor of aphile.

Being open minded is a reference to all aphiles and our individual biases and experiences. Innovation will transcend this limited perspective.

Let's build this unit Charles. A DHT 300b tube output amp with SOTA room correction and built in dac. We can address further noise reduction with a cutting edge hybrid pre and amp section. 
Understand fully stfoth. I really do. I will always have "some" tube amp in my home as I am in love the design and building of these pieces.
