I think that a case can be made for the *role* of individual components in the chain.
What I mean is that an amp does a known number of things to the sound (not fully known but well understood by experts). So does a speaker.
I agree with Mr. koushik that starting with speakers is a good idea, but if Mr. bose wants to go with the amp first, then he can; provided that he studies the effect of amp on sound and then listens/demos the various amps in the market and picks the one he likes. (In case you do that, please share your experience as it will help us learn something as well from you instead of just sharing with you what we know).
What I can tell are some starting points in that direction:
- There are classes of amps by technology used - Class A , AB, D & T. Class A being most organic & T being least natural. (Debaters will contest this but I have heard the difference and I know that along with the toroidal transformer, it does make a clear difference).
In my opinion, if you have such a budget, then you can aim to go for the next higher technology i.e. jump from Class D to AB or even to Class A.
That would make the most difference instead of buying the same tech from a better brand.
- The second thing of course, is buying a better implementation of the Class of amp (which is more fundamental) i.e you can buy from a reputed brand. If not the best then maybe medium.
What I mean is that suppose you choose to upgrade to Class A amp. Clearly, a medium grade implementation of Class A is going to be better than a reasonably high-end implementation of Class AB.
One medium end value for money brand that I know of is emotiva.
This one seems to be their lower end model.
And this seems to be its higher version.
They are monoblocks. So you will need two of these. One for each channel.
If you find Class A integrated amps in that price range, then let us know abt them !
One higher end I know would be Nelson Pass. Maybe Burmeister also?
Enjoy the journey !
