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

I also can recommend KT100 after owning several QS products.  I currently have Mid Monos.   They have been super reliable.  10 years old and have been trouble free.  Many , many hours on them and only a few tubes over the years.   

@marshinski15    I believe you have decided on the right course. I don't think any of your amp choices would have been a suitable match.

I briefly owned Quicksilver Mid Mono's, but felt I needed more power, so I was able to trade up to the KT Mono's with KT 150's (100 wpc).   I agree with @soix that the amps you are considering are likely not a good match for your speakers.  I'd be shooting for something in the 75 to 125 wpc range.   McIntosh MC275, offerings from Rogue, Quicksilver would be a good place to look. US Audiomart has a good selection.

I would avoid any amp limited to various "contemporary" powers tubes which may not be available in the near future.

This would include all the KT tubes starting @ KT90 and going upwards.

Same goes for anything using 6H30 small signal tubes.

If you want "blunt, I’d pass on all of the tube amps on your list, and ditch the Benchmark DAC, I had one and could not stand it. One of the most un-engaging dacs I’ve owned.

As for your speakers, and this graph, (and I’m a 100wpc mono tube amp owner myself) I’d be looking for a nice velvety 200wpc mosfet solid state amplifier. I think you’ll be much happier and your speakers deserve the right matching amp imo. 3.5-4.0 ohms is just getting too far down there for most tube amps. The amps I’m using right now would do it, and so would KT Monos yet I’d throttle expectations after seeing this graph and considering what tube amps you might need.

Worth checking the used market for nice SS mosfet amps (too) if interested.
