I go to many audio gatherings per year ,the New Luxman power amp retails for around $20k is exceptional . Call Anthony at Perrotta Consultants 

he is good to work with and fair  pricing , ,he also Carry  Accuphase 

Another very good one is Krell New KSA line which too is exceptional and made in CT U.S.A ,  He has their line also as well as Bricasti which he may have a demo model. Do some research. .

There are many excellent suggestions so far.  If you are casting a wide net;

I just updated my preamp (to Audio Research) and as it burns-in my biggest impression is that my Ayre Amp (V5-xe w upgraded capacitors: 300 W) sounds great - voicing is as-good-as/better than many more expensive SS amps that I have heard in shows and at showrooms: I do NOT feel the need to upgrade my amp to make the ARC preamp sing.

This morning AG has only one Ayre Amp, the higher-line V-1x, for sale (at The Audio Room, below $5k). Refreshed w new Caps, you may find you saved $20K.  

I have no affiliation w Ayre or The Audio Room.

For 25K I would go with the MC1.25

Amp vs Preamp.....Right now my Borresen X-3's are singing. $10,000Tube preamp going into...wait for this....the New NP1 Power amp ( 55 watts into 8 ohm) Van Alstine amp. ( first run is sold out)....What a musical magic amp this is for $1,199.....always spend More on the Preamp than you do on the Amp and Tube the pre with SS on the Amp. Nirvana.
