Best tube integrated with Merlin TSM-MMI?

Never heard the Prima Lunas, but I imagine Bobby would suggest the EL34s
versions rather than the KT88 version if you choose to take that direction.
And if you considering the Prima Lunas, it also suggests the possibility of
Cayins as well - they look beautiful, but only heard them briefly. 30-40 watts
should be enough power to make them sing.

Couple of other integrated have popped up on my radar: Mastersound Due Venti & Grant Fidelity Rita 880. ???

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.
