Ericsh, this is not exactly on point, but I do have a Primaluna Prologue One and a Cayin T100, close to your request but no cigar.
So FWIW, I use the One with EL34's (in preference to a Prologue Three & Five combo, which I also own, with KT88's - the One has a slightly warmer balance and concurrently less definition than the 3/5).
The Cayin T100 with stock tubes was cool in tone, you could call it bright but I think the problem was not in the highs, more an absence in the lower mids/upper bass. I changed out ALL of the stock tubes! With those changes I now have speed, resolution, and some warmth. I highly prefer the Cayin as presently tubed. I went thru a raft of tubes with the PL and I'm presently using stock (EH) small tubes and SED EL34's.
My stereo is on all day so I use the PL when I'm not sitting in the sweat spot - its a lot cheaper, and frankly not that bad.
Both units have been in the house over 4 years and there have been no reliability issues. I did have some with the 3/5 and found the dealer/distributor flawless in providing fast and effective service.
Hope that helps a bit.
