Anything SS sounds better than D'Agostino ?

Another is Mark Levinson 33 Monoblock amplifiers. Boy, you need a bobcat to lift the 400lb each behemoth, lol! Dam, they sound good though.

Inna, I enjoy listening to music and also take great joy in auditioning gear.  Consequently, I collect (hoard) much gear.  As has been stated before, synergy is key (everything).  For example, I have a pair of fully rebuilt ML 33H, these amps pair up well with my Talon Phoenix speakers (ceramic drivers), however, my Pass XS300 and Krell KAS sound better with my Rockport Cygnus than when using the ML 33H.  Additionally, I have several Pass Aleph amps which sound sublime when paired up with my Altec Malibu speakers.  I have several JBL (4343, 4350, 4430, the original Everest) which pair up well with tube amps and SS pre-amps.  I prefer my Boulder 2050 to my 2060.  I had the Vitus SM 101 Mk1, but preferred my other amps and thus sold the Vitus.  My Krell KSA 200 pairs up very well with my Duntech Princess speakers.  In regards to the D'Agostino S-250, it's a great amp, reminds me of the older Pass amps.  Pick your poison...

Jose,
 I will in time..
You are right about the synergy, of course.

Inna, a few more to consider;
The Vitus SIA-25 is spectacular, assuming your speakers arent power hungry.  I used the SIA-25 with a pair of MBL 111-F for a while.  Coda products are HIGHLY underrated.  I prefer full class A Coda amps; these are giant killers, trust me. Additionally, Coda pre-amps are tremendous.

I own a Coda S-100 with matching pre; wont get rid this combination for anything.

Respectfully,
Jose

Jose, 
You have a lot of great gear.
Coda. Never auditioned them. Or Vitus
