So you need 8 power tubes...at today's prices that gets an "ouch." Yeah I love the XA-25's utter transparency, but my Had amp just looks sad sitting there and it's easy to swap the wires over to it so there's that, and I'm always amazed and entertained by the differences between these amps. Fun...it's just fun...
KT-77 vs. KT-66
As I've had my QS Mono 60s, I've tried a variety of tubes. I have sold off my KT 150s, and use KT-88s from time to time, but what I really love are KT77's.
I'm thinking of getting some KT66s, thinking that lower powered tubes are better (to my ears) matches for my system. I just don't know what the KT-66's sound like.
Question: If you have compared KT77 and KT66 tubes, what would you say the sonic, audible characters of each are? Is there a difference you can hear? What does the KT66 sound like -- to you?

hilde45- Just for some new audio kicks NOS 6L6GC subs can still be found for reasonable cost. You're probably familiar with Brent Jesse? "Also, I would like to hear how vintage 6L6’s sound in a Primaluna" toddnlg- if you're referring to the LOW VOLTAGE 6l6G(not GC), been using RCA 6L6G in a PL HP as the preferred compromise for EL34 mids/ KT88 bass.

Talk about going full circle. One of the best sounding amplifiers I have ever owned was the Audio Research D-40 with 6L6s. I recently paired it with an Audio Research REF 6 and it added another dynamic to my Sonus Stradivari. Much more detail. Just could not live with the low power so I have gone back to a REF 160S with the KT150s. I am using a Rogue Atlas Magnum as a test bed since it can accommodate the KT77, KT88, KT90 & KT120 family of tubes for comparative purposes. Something to be said about the older tubes. I am leaning toward the KT88 with good bandwidth and power. Glad I kept my classic collection of tubes from my Dynaco 70 days. |
@hilde45 If you can't use 6L6 or EL34 tubes it's likely you can't use KT66 or 77s either as they are each very similar to a 6L6 and EL34 tube respectively. |
