RE: Moving From 845 tubes back To KT120/KT150 based amps ???

Posted by decooney on December 19, 2024 at 16:29:29:

Got it. Thanks for the responses. This was helpful and comparing to other forums - No further questions from me on this.

Similar to what member @Mick Wolfe shared here - The other answers and supporting details I was looking for was found over on AK from amp designer Ralph at Atmasphere. Its my 93db/6ohm speakers as the culprit. While they do well with my PP Ultralinear amps at 100wpc or 50wpc Class A SS amp (at low or model level volume) the lower midrange and upper bass and continued dynamics i'm looking for is NOT going to be found with even the best 845 triode mono amps (with my speakers). Similar to Mike Wolfes comments - Atmashpere Ralph e covers many reasons for this being the case and agrees with my own concerns using 845s with my speakers. Also Luke at Manley said something similar to me a while bck about me trying this with amps lacking sufficient bandwidth for my speakers. Got it better now,

This helped, Thanks.
