solid state vs tubes

Maybe.

In general, I believe higher ratios of input impedance on a device downstream to output impedance of the device upstream to always be a good thing, all other things aside.

Of course, in reality you can't just conveniently focus on on e factor and push all others aside, so who knows in any particular case. No one ingredient alone makes for good soup.

my original question has not been answered:

has anyone participated in a "blind" test comparing a solid state amp to a tube amp and been unable to discern the difference between them , say 7 out of 10 times ?

MrT:

That was not your original question.

Which is it?

Mapman, One of the advantages of ss amplification is it's inherently low output impedance, low speaker impedance speaker loads are almost never a concern. There are some, that believe that the best results occur when impedance's are more closely matched (Jeff Roland?) rather than having a low to high ratio. I suspect it might have more to do with application. It appears to me that it is much easier to achieve better bass response and steadier impedance loads in lower impedance speakers than in higher impedance speakers.

I have had many tube and solid state components , I've slowly gone all S.S. . The last 3 to 4 years tube and solid state has nearly reached convergance , at least in the higher end . The break down rate on the tubes was only slightly higher retubing for my preamp was $ 550. per year , my power amp $2200. per year , the odd time you would get a bad tube and have to start over . Go over your recommended tube life and things would start to go very wrong , so I was listing less to save tube life , also the heat from the tubes in the summer meant reduced listing time . I loved my tubes , but I have found S.S. gear thats equally as injoyable , although somewhat more pricy up front . M
