solid state vs tubes


has anyone compared a tube amp to a solid state amp and discovered that the diffference sonically between them was undetectable. ? if so what was the tube amp and what was the solid state amp ?

the reason for the question is the basic issue of the ability to distinguish a tube amp from a solid state amp.

this is especially interesting if the components were in production during the 90's , 80's or 70's.

if the components are in current production the probability of such aan occurrence might increasea.

why own a tube amp if there exists a solid state amp that sounds indistinguishable from it ?

I feel my roland model 6 amps come very close to the sound of my audiovalve challanger 180 monoblocks when driving usher rw729's or soundlab m2's but the tube amps have the edge in my opinion driving my speakers.
Where do you stand on your own question I am just wondering.
I agree with Pubul57 100%;don't get wrapped up in reviews
and always let your ears guide you in this process.
Hifisoundguy you really believe tube audio will fall to class
D amps?
Why do you think this I am just wondering;You mention tube problems and tube owners don't want to talk about;all I can say is device or tube failure occurs on both products and I don't think there is a huge % that leans toward tubes;when you own tubes I have learned that it is not a major or audio ending event;what happens when a output transistor or output module fails its part of the hobby;no big surprise in my opinion.
I have audio valve challanger 180 mono's and jeff roland model 6 monoblocks and think both products do their job extremely well but I just think in my system the tubes have a slight edge in overall system performance.
Mrtennis when you have tubes on these speakers does that treble response occur?
hifisoundguy all the problems except tubes also occur in solid state gear as well;the tube issue is easily resolved by buying from sellers whom other members recommend or ones with stellar credability.The popping noise that comes and goes is one that I circumvent by testing my tubes on a b&k 747 tester on a regular basis;how do you test your ice modules,mosfets,or bipolar transistors;can be tough to desolder from a multilayer circuit board.I don't think a tube degrades quickly unless maybe it is a infant mortality
related;which can also, happen to solid state due to ESD or even high humidity causing leakage;leading to breakdown and failure as well.
I think you are hearing the way the impedance of the speakers is acting when being driven by tube amplification
vs solid state power;it just so happens you are hearing it in the treble frequency range;its all part of matching the proper amps with the speakers in my opinion.
mrtennis older jeff roland models 6,8t or 9t might work for you;my model 6 monoblocks perform quite well on my soundlab m2's;the original owner of the m2's was driving them with model 9t monoblocks.It might be the sound you are striving for.
Magfan the hp4062ux is a parametric tester used with probers to test wafers when they come out of the fab.
Unsound the zeros have a 60 day trial period so you can try them on your own system with no risk.
