Very true, Dr. Bass. Actually Kolkata would be even far behind Mumbai, Bangalore and Chennai in this regard, even though officially there are dealers here for some big brands. But they do not get the stuff you'd like to audition. If you want to buy for sure, only then they'd get it for you. Last year when I wanted to audition amps at around 1L-1.5L lakh range, I could audition only 3 amps here in Kolkata, at the stores.
But listening to good equipments is essential before one undertakes a major project like you undertook (going to sgp and all). That's why I have been making a suggestion of our TS to go around and look for decent installations at people's homes, in addition to what he can manage at the stores here. Without this, one of two things usually happens: 1) One buys the first thing with the wow factor in sight, 2) One gets confused with so many options (no offence here, Trinanjan. I've seen very mature people making similar mistakes at times, including of course myself).
For example, Dr. Bass, if you did not have appreciable experience of hearing decent stuff already, I'd say you'd have been completely confused by all those speakers (what an effort though, I must say).
Now a bit more on the tube/SS and your genre (Westren Classical). This is not really my territory, this is an area for the experts, but nevertheless I'll go ahead and see if the experts take notice and say something to benefit my understanding.
The absolutely very best recordings (probably will cost you an enormous amount) of Western classical recordings may have a dynamic range of 25 db (is really a guess, can anybody confirm?). Usually found good recordings may have upto 15 db of dynamic range. Now to be able to swallow a dynamic range of that kind may not be easy for low-powered tube amps. I have not tested this with my system, because I do not have that much of good quality Western clssical on CD, I have a few though on vinyl and my TT is not working. I'd like to see how such a huge dynamic range is handled in my system. We have tried the Coaltrain, and it passed with distinction (most recently when Pratim came, no strains and absolutely smooth even at quite a high volume). This is the reason why I commented in my last post that perhaps a SS amp would suit the TS better, but to withstand such dynamic range, even the SS amp has to be great. I'd really like the experts to comment on what I have written above.
Well Trinanjan, you also said something about your current source, the CA 640c CDP. It's not my favorite in that price range. I myself own a CA (740c), but there is a day and night difference between these two. Yes, sources are very important. But take it up later as audio_engr suggested; first up: the speakers
