Recommendation Tube Integrated

@mathiasmingus-Have you gotten a tube integrated? If not, I'd look at Unison Research Triode 25. 45 W in Pentode/25 in Triode. The Triode meets your smooth and creamy criteria, as well as being resolving/involving.

I agree with the poster above who recommended the Synthesis A100 Titan.  It is a rich, smooth and natural sounding amp with lots of punch too.  I heard 40.2 with that amp or its little brother, the A40 (single pair of KT 66 tubes per channel vs. four tubes per channel on the A100), and the sound was quite good.  The 40.2s are a somewhat touchy speakers—they can sound sloppy and sluggish with amps that lack the punch of the Synthesis amp and it is not just a matter of power.  The best I heard from them was when they were matched with a twenty-something watt amp-Audio Note Gaku On-that costs a fortune.

PrimaLuna EVO 300 or the EVO 400

Dollar wise after owning a Raven Audio Osprey with Raven Audio Corvus Speakers and the best tubes on market in Osprey from Dave Thomson Collection for 5 years  I was a very happy customer....It produced musical detail that I wondered if I could hear any more from another amp.. I have tinnitus pretty bad and when I turn on music I am listening for every sound coming from those speakers and sure my ringing is stopping certain frequencies I can hear..

I decided after talking to Dave to step up to a Reflection and OMG what I hear is incredible ..But the Osprey Dollar wise is the best for the money..

Good Luck in finding your sound Amp to make you happy
