Primaluna Dialog Two Integrated Amp vs Cayin A-88T

Buconero, have you stayed with the KT-88's that came with your Cayin or have you experimented with el34's?

Learsfool, I guess same question for you.

Thanks.

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.

Thanks, Newbee. Maybe I missed something, I'm new to tubes. But what did you use for replacements when you changed the Cayin "stock tubes"?

I used re-issue Tung-Sol 6550s for power tubes, EI 6CG7's, EH12AX7, and JJ/Tesla 12AU7's. The Tung-Sols have solid bass with a bit of warmth in the upper bass. They are not additive in the higher frequencies as are many of the KT88's, just right I think. FWIW, they were somewhat dark in the PL 3/5 and the One.

What about customer service? I know Rogue is fantastic being located in Pennsylvania.

Rhljazz. Can I put KT120's in my Cronus Magnum? What might I expect to hear as opposed to KT90's?
