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 ?

It seems that Nelson Pass, for one, has always tried to make SS amps that can perform like tube amps...are they indistinguisable from tube amps? Well, there are alot of Pass/First Watt owners out there that might be able to add their 2 cents on that....

I'm a Pass fan. I've auditioned the Pass Labs XA-30.5 and owned the Pass Labs XA-60.5 for use on Silverline Audio Sonata III speakers (a great match).

I have also compared the the First Watt J2 and First Watt M2 amps with Audio Note Conquest Silver 300B amps on Audio Note AN-E/SPe HE loudspeakers. As a Pass lover, I *really* wanted the J2 or M2 to equal or surpass the Audio Note amps, but it was not the case, in my opinion. The tube amps on the AN speakers provided a more palpable and three dimensional presentation that could not convince me to sell the $14,500 Audio Note amps in favor of the $3500 First Watt amps.

As much as I wanted to put the monetary difference (and maintenance difference) in my bank account, I had no regrets returning the First Watt amps...(which could very well be superb on the right speakers).
Tvad, I had the Aleph 2,3,J and XA30.5 - I no longer have any of them, but three tube amps; I really did want to have an SS amp, so I tried some of the "best" - but with my speakers.....
Can anybody tell me a pair of speakers that sounds the same well with either tube or SS amplification?

I can think of different speaker/amp combos, some SS and some tube amps, that sound very similar, but I cannot cite a case where a tube and SS amp sounded the same with the same speakers. They will almost always sound different with different resulting sonic strengths and weaknesses, the the listener must decide which is better.

Unless you are Bob Carver and your goal is to emulate one amp with another. I do not know any vendor whose busines is based on that these days. Each quality vendor typically does their thing well, be it SS or tube amps or both. Choice of amp will determine choice of speakers or vice versa.

I think this is the bottom line. Build your system to meet your needs. Use tubes or SS as desired, but do not expect touse either to the same effect with the same speakers.

I know that some Silverline Sonata III owners drive them with tubes, and other owners drive them with solid state. For me, tube amps never got it right, but others disagree.

I *think* Wilson owners are divided among tube and solid state.

Having said that, I doubt anyone will say the speakers sound the same driven with tubes or SS.
Harbeth seems to be as fasinable with SS as tubes, whereas my speakers are proabably 98% tube users.
