In Reply to: RE: Moving From 845 tubes back To KT120/KT150 based amps ??? posted by Tre' on December 19, 2024 at 06:38:02:
@Tre' @Chip747Thanks for the replies and inquries. Its the opposite of your thoughts. I listen at LOW volume levels, and this is likely more of the constraint with lighter amps with less iron in the power transformers it seems. I'm guessing of course, trying to inquire before I dump $ into some 845 monos to try it out. No demos on those around here. I don't listen at high volume levels at all. The challenge to achievce that (weight in the lower midrange/body) has been the lower powered combo UL/Triode 10-40w switched (EL34, KT88) pentode tube amps and dedicated triode (KT150) amps I've owned and tried from Dennis Had, Cary, Inspire. Nice sounding but my current UL amps stomp them. The goal is to try dedicated Triode amps, maybe. Im not sure how much heft/weight/tubes will be needed for a Triode amp to match the weight/body I get now from the higher power UL amps I use now. Hope that makes sense.
As soon as I swap in my other Quicksilver Mono 120 (UL amps) with KT120 or KT150s do I immediately hear the lower midrange "weight" and mid to lower body/bass. These amps also have some monster dual power transformers on them and sizely power caps on them with tube small tube triode front-end and SS rectifications - if it helps to explain what I mean by real weight to the sound from the main speakers. Yes, the other full Class-A SS 50w amp does a little better than the 10-40w tube amps switched in triode.
Re-Ask: would some hefty 845 monoblock TRIODE amps do as well as my big UL amps I have now. I guess that's what I'm trying to figure out in advance of buying a set and possibly regretting it and going right back to my UL amps.
Note: I do enjoy trying and testing differnet amps with the custom speakers I build. Long story, I worked at a local speaker Co and do this for enjoyment, that's. You guys are the real tube gurus here on TubesAslymum :)Subwoofers: I have two Scanspeak 12" stereo subwoofers I also build and use for 50hz and below. This helps support the absolute bottom end due to room issues I cannot change in a shared family room. I turn these subs off to ensure the main speakers are doing their best, for fine tuning. No, I'm not changing my speakers, they do sound glorious now with good UL/SS amps. Any of my current and former SS amps, never an issue. All the lower midrange body and weight to the sound, but not tube, and not real triode sound I seek in some hefty well designed tube-triode amps. Maybe. Now back to the real triode amp inquiry if I may, please. Thanks again for your help and insights.
I may not be explaining well - a local colleague and 55-year-in-business audio shop owner told me that a really well designed dedicated pair of Triode amps with true triode tubes and hefty iron behind it can do better than some of my former whimpy 10-40w switch triode tube amps I've tried to hear "triode". He keeps telling me what I've tried so far is not real triode, and I need a real pair of real triode monoblock amps, LOL.
Meanwhile, I'm saving up to get there some day. Hopefully that helps explain. Apologize if I'm not explaing well. Happy Holidays.
