Question 2*100 watt @ 4ohm TK2050 or LM3886 Gain Clone??

I'm looking to build an amp for my self, something That I can listen to my Trance/House and the rest of the music without any problem.

So I'm here stuck with two choices:

LM3886 High End Power Amp Refer Gaincard New - eBay (item 120479781649 end time May-10-10 01:00:56 PDT)

and I'm not really Sure which one to go for!
which one of them sounds better? and is better over all,
Money wise I know it's cheaper for me to build amp with TK2050 Board but I dont wanna go cheap on my sound so I wanna know which one I should get!

thx

why stop with just one? Try a LM3886 at 27 volts built point to point on the IC chip itself. Then build a truepath from 41 Hz. It is based on a TA3020 tripath chip at 150 watts into 8 ohms. One of these will fill the void. If you are picky about your components, you could get both done for 350 dollars or less. It depends on what items you might already have.
