Seek Tube Amp to Flip-Flop with SS Amp


Having listened to a variety of systems lately, using a variety of sources, I am convinced that some things just sound better using a SS amp and some using tubes. I currently have a McCormack DNA-225 which I like very much. I would now like to add a tube amp to my system so that I can use one or the other without exchanging too many of my existing components, PC, cables, IC's. Would be obliged for suggestions of a tube amp in the $2-2.5K (USED) range. Thanks.

System:
DNA-225 w/H Tech AC-11 - H. Tech Truthlink (copper) IC
Kora Eclipse preamp w/Ensemble Megaflux PC - H. Tech Truthlink (copper) IC
Nottingham Spacedeck - Spacearm w/Tracer#3 & Origin Live w/Dynavector 20
Rega Jupiter CD w/H Tech AC-11 - Nordost Red Dawn IC
Older Sony Tuner - stock AC - Zu Oxyfuel IC
PSB Stratus Goldi's w/H Tech pro9 biwires

Tweaks to numerous to mention.

If I remember, The Stratus Gold i is 90db efficient. If your room's not too big, the Cary Rocket 88 might work like a champ. I use one to alternate (summer and winter) with my Bel Canto EVo2. My N804s are only 87db efficient, but my room's small at 11x13'.
Hi 4Yanx; I'm also considering doing what you are planning so I'll follow your thread with interest. I've been thinking of the ARC VT-50 (which is a "stout" little amp, and also the bigger ARC VT100 MKII. The MKII can somstimes be found near $2.5K, and the VT-50 in the $1700-1800. range. I haven't auditioned them in home though. Good Luck. Craig
Conrad-Johnson now owns McCormack. Many people here on Audiogon seem to like the sound of these two when combined. They have similar specs. If the rest of your system works with McCormack it should inter-face with C-J (at least on paper). Most people think C-J has a "clasic" (for better or worse)tube sound. I am not that familiar with the rest of your gear, but C-J would appear to be a good candidate for your needs.
If your speakers are 90+ and fairly linear, you may have the option of 300B SET as well as Push-Pull.

To my ears, SET beats out push pull every time provided your speakers are efficient enough and you are not a bass freak.

Either way, I would recommend Amps that will allow you the utmost flexibility in tube "rolling". The Cary Rocket 88 and DJH Version of the AES Superamp (Cary subsidiary) are good choices on the push-pull side as you can tinker with several different tube types.

If you want to explore SET and want to keep your present speakers, I think you may have just enough efficiency for a nice 300B Amp. Cary,Welbourne, Sun, Wright Sound Company, Wavelength and others make Amps that will be in the $2000 to $2500 range. Add some Western Electric tubes and you will be in business.

Good luck
