Best tube integrated with Merlin TSM-MMI?

Mastersound is top notch. Very underrated OR unknown, however the el34 for sale has gone for as low as $1500. Good used deal at maybe $1800. Haven't heard any below the 300 B or monos but I don't think they would dumb down any model.

Thanks for the tip, Bjesien. How does it match up with the Merlins is the question?

I had my eye on those Due Ventis today, but thought it just not be enough juice to drive the VSMs, let alone the TSMs, but on paper they do sound like something I would have liked to have tried - like the Almaro 318s[?] = again, not enough power methinks, but also an intriguing unit.

20 watts, which seems to be the Due Venti's rating, is likely not enough for the TSM-Mmi, in my experience. The Stingray offers the option of 18-20w in triode or 36-40 watts in ultralinear. As much as I like the sound of triode power (I also run a 2A3 amp in another system), I found it to be inadequate in my admittedly large room. The midrange is wonderful but the top and bottom ends get a bit ragged. Ultraliner, though, sounds extremely good through the whole sonic band. Of course, YMMV.

21 watts for the Primaluna Dialogue Two (38 in ultralinear) -- not much different than the Mastersound Due Venti.
