... and the one you say is the same at $85.00: So, I'm confused. These two do not seem to be the same and their names are different. In fact, one is a CV 181, the other is actually a 6SN7. What gives? Also, I was referring to the GL KT-66 in my previous post. If you think in your setting the Treasure KT-66z is better overall than the GL, let me know. Thanks!

I guess I am incorrectly calling the UK 6SN7 a CV181. Appearance wise they are similar. I have no idea why they named UK and don't really care. Funny thing is the Treasure CV181 is a 6SN7 electrically.
Yes, I prefer the Treasure KT66z over the GL KT66. It has more texture and body and a 'sounds real' midrange. A lot of tubes sound good in these amps but If I had to live with one *I* would choose it. The GL is an excellent tube though. It's all about synergy. Is the KT88 still the top dog for you? |

It sure looks as if the Treasure KT66z is a find! |

Of course, as you have rightly said, these synergies may change after the caps upgrade. With respect to KT-120's, I'm under the impression that our Inspire amp is designed to be optimal within a select group of tubes in the center of a normal distribution of compatible, relatively similar output tubes. The further one goes to the tails of that family specs distribution, the more we force the amp out of its sweet spot. Robustness and optimal sound are not easy to achieve in SET designs, as nature is all about tradeoffs. Now, I have not yet read that review and I may be totally wrong, but I'd bet the best sound with our Inspire amp is probably achieved with KT-88, KT-66, 6L6 and 6V6, with the latter somewhat anemic in my rig. As good as the KT-120 may be, forecasting good sound potential based upon the isolated qualities of an output tube is risky IMO. Besides, tube-rolling effort and expense grows exponentially with a larger range of tube candidates. Last edited by Musica Amantem; 04-10-2016 at 05:16 PM. |

Has anyone used a KT120/150 in these amps and really liked them?

He included KT150's with my amp as it was the tube he made that amp for (it is called an Inspire KT150). |

I've been using TS KT120's for a couple of weeks now and feel the low end is there - tight bass, but I think you sacrifice some midrange emphasis. I've been swapping drivers - NOS Syl 6SL7's and 6SN7's to find the right combo. Might drop in some RCA's I have and hear what I hear.

However, it is a high power push pull amp and clipping may not be an issue. Musica Amantem likes big orchestral music but clipping might be an issue. |

BTW, I listen to acoustical Jazz and chamber music 75% of the time, so it's only that other 25% that concerns me in the "slam" department. I would expect speaker profiles to be the other important synergistic potential for any amp. Last edited by Musica Amantem; 04-11-2016 at 08:33 AM. |
