The updated Dynaco ST-70 is a wonderful amp and a total bargain at its price. This is a design that has sold over 350,000 amps of the the past several decades. Tube rectification, better power supply than the original, and improved tube choices for the preamp and driver functions improved the amp even more. Lots of power (35W) in its ultra-linear mode (which is how these transformers were wound) so you should be able to drive most speakers. I owned this amp and was very happy with it, as it compared favorably to my Decware Torii (another EL34 amp.) As a bonus, the tubes this amp uses are affordable ('m a former 300B amp owner!)
I'm going to buy my first tube amp. I need honest blunt opinions
Recommendations please. I am thinking of dipping my toes in the tube amp water. For the longest time I have been tempted to buy a modest tube amp to run my Monitor Gold 300’s at 90db.
I’ve been toying around, researching the different characteristics of SET, class A, class AB, B Ultralinear tube amps for months. It’s a bit much. As far as the reviewers go, they are too vague. They are afraid to be upfront honest.
Sources are a Parasound JC 3+, a Innous ZENith Mk3, and a Oppo going to a Benchmark DAC, then all go to a Benchmark LA 4 preamp that will feed the new amp.
My room is 16 x16. The speakers have a 12-foot spread. I sit 14 feet back, so it’s not that big of a room.
I have narrowed it down to four candidates.
A used Canary Audio M90 300B Tube Amp at 24RMS,300B push-pull stereo triode Class A $4,000
A used Jadis Orchestra Black, 40 RMS, Class B $4,000
A 16-year-old, Used Cary Audio Six Pac Monoblock’s, 50 triode watts A/AB $2,000
A new Dynaco by WILL VINCENT 35RMS Ultralinear $2,300
