2*100 watt @ 4ohm TK2050 or LM3886 Gain Clone??
 
Hi!
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:


2*100 watt @ 4ohm TK2050 Class-D Audio Amplifier from Sure..

2*100w 4? TK2050 Class-D Audio Amplifier Board-improved - eBay (item 350344146851 end time Apr-28-10 12:27:28 PDT)

and

LM3886 High End Power

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

What i have read from this thread:

http://www.diyaudio.com/forums/class...00-tp2050.html

I would prefer to use lm3886's.

Wit that one option you have there basically the ONLY things you need to buy is a 160 - 220VA 25 0 25V toroidal transformer and a heatsink for the lm3886's.

The TK2050 is suited better when using a 24V regulated powersupply ,something decent with low noise. Not sure how their cost compares to toroidal.
Personally a constantly running Fan on that tk2050 would irritate me a LOT.

So my personal input is to use the lm3886 kit. They should do GREAT with those speakers. It will be VERY easy to do modifications toe the lm3886 kit also.
If you have assembled everything and give a circuit diagram and we can see if further improvements can be done to design.

I have 2050 amps and 3886 amps. And 3875 amps. And 7250 (previous champ) and Hypex amps. The 2050 with a 36v MeanWell at 32v sounds much better than any other amp I have ever tried, total cost is $100 and you can have it playing within 5 minutes of opening the boxes. A single 3886 is not that great in my comparisons. Running two 3875 bridged from a true balanced source is much better and almost gets you into the same league as a good 2050 amp. The Sure is the cheapest and the quickest with all of the connectors on the board. The stock parts of a 41Hz kit will be better but you have to build it. The Truepath 3020 modules from Connexelectronic could be even better if you wanted to spend a little more than the Sure 2X100. Class D isn't just for efficiency. It sounds better. Ultra transparent, explosive dynamics, and sounds much more powerful than it's specs.

I got a question tho
can i run 2050 off my HP Printer ( HP Photosmart 2610) Power supply? 31v @ 2.4A
and with that Hp power supply would it sound as good as with MeanWell ps?

Some guys get good results with printer SMPS and some didn't. I would order the Meanwell at the same time as the amp and be done with it.
