Hi Guys,

I am planning to buy/build a dual IC amplifier for home use. I would use the same for driving my speakers Bass 12?, Mid 6? and Dome Tweeter 1.25?. I love loud but distortion free quality sound output with heavy bass.

Looking on the internet I found lots of chips that can be used. Some of them are:
TDA2030A
TDA7294
STK4141
STK4050
LM3875
LM1875
LA4440
6283
2N3055
TAS5630

Now I am confused as to which is good and suitable for my use.

Hence I request you to please throw some light on various aspects of the above chips.
Please let me know the following info on each of the chips mentioned above:
a. Sound Quality (subjective)
b. RMS output
c. Price for a buying/building a dual IC amp
d. Other aspects like Life of the IC, Ease of availability in India

Please put in your thoughts. Believe that it will be of great help for me as well as for lots of others who are planning to buy/build some decent quality amps.

Thanks
 
Also add LM3886 to the list. It is basically an improved version of LM3875 (Gurus pl correct me...I may be wrong here) and provide an output of appx 60-70 Watts.
But anyway, 3886 is held in very high esteem among DIYers. Search ebay for kits.
You basically need high wattage amplifier to drive 12" woofers. Hence the likes of TDA2030 (with 18W RMS) wont be enough.
 
Thanks Anurag for pointing another chip.

Awaiting other members to please contribute their thoughts.
 
Purchase the Audiolab 6000A Integrated Amplifier at a special offer price.
