Tube amp Low end Bass question

There are some relatively high powered SETs but the more power the pricier they get.  What is your budget (the MC275 is $5750)?  Do you have room above that?  Stereo or mono-blocks?  

I sell SET and Push-Pull units for Art Audio but my stuff is a bit pricier than Mc and is relatively low power.  I can help steer you toward something that is a better fit though.  What part of the country are you in?  

Also, the above comment on 845s and 211s being kinda scary in a SET stems from them running REALLY hot.  I agree.  Quality is critical.  You want separate transformers for the heaters and audio circuits and placement of internal parts has a big impact.  Designed right they only run a bit hotter than a push-pull.  Designed poorly it is like having a space heater in your room.    

With 211's and 845's, to get the higher power output, the voltages on the plates of the tube have to be pretty high--meaning properly insulated wire and good electrical construction practices, which are not always found on cheaper amps.  Also, the output transformers have to be of quite high quality to benefit from the use of these tubes and the proper transformers are quite expensive.  These tubes do run hot, but, that is not the big concern that I have.  I do agree that layout is particularly critical for the 211 and 845 amps because of the heat and high voltage issues.  While I have heard some very nice 211 and 845 SET amps (Viva and Wyetech come to mind), to be, the best sounding SETs are the lower powered ones utilizing 300b, 2a3 and 45 tubes.  

The McIntosh MC275 is a pushpull amp, not a single-ended triode (SET) amp.  The current production model is, to me, pretty lousy sounding (mushy and lifeless sounding at modest volume levels) and the construction is shockingly shoddy.  With McIntosh, it is the older stuff that one wants.   

Hmm. I'll have to do some further digging on the 275. Maybe a nice Mark V is the way to go. I've heard a Mark VI...sounded nice...however only for a few minutes and not in my own system.
