thanks!
the tweeter and i think the mids-driver of one of the speakers had gone bust. when went for the 'diagnosis', came to know that the whole config would have to changed. i chose the recommended Peerless Denmark drivers. though they were a little costly over the local-counterparts, but being good, decided to invest on them. didn't want to spend much, otherwise, as you have written above, it would've perhaps made more sense to get a new set, or most preferably, from a wide array of well-maintained FS-sets available for sale on forum ('perhaps' because, sometimes, even till a range of say about 50k, a branded set won't be able to deliver that kind of sound as what a custom-built and balanced/fine-tuned set with carefully designed crossover would, as per one's own tastes). so got the work done! i had got these FS (
DSE AE2922; these are the front-speakers of a complete wooden-cabinet 5.1 HTS, being earlier available at Croma years back, but no more now) from a forum-member, for 7k, and for the price, the earlier drivers-config would produce some really terrific, fast-paced sound, and hence, my present amp used to compliment them well! this is how they used to look earlier:

now, since the new drivers are better & more refined, i would need to change the amp to a more musical one, without compromising on the power. the first & foremost thing to choose for such a set-up should be a good source. have got hold of a Logitech Squeezebox Classic for now (a legendary line of music-player/streamers, with a good DAC); next in line would be a still better amp, and further ahead, i already have the speakers.
however, those who are seriously interested & looking forward to getting a good set of floorstanders without going overboard on spending, then there's a really good offer going on for the new & widely acclaimed Pioneer SPFS52 speakers (again, the fronts of a full 5.1 HTS). check a few reviews on them; for instance,
this. when i was about to invest in the new drivers, these were not available in the country, otherwise would've seriously thought of giving them a go. presently, these can be had for 15-20k in the offer, and for 35k for the whole system, which, i, and many others as well, think, is a steal! if anyone's genuinely interested, PM me, and i would redirect you to the source.
