Look What Santa Brought !

The latest addition to the family is my first attempt at a TDA chipamp. This is the TDA7240 kit from Jim's Audio on eBay. Had a little confusion on BTL/Stereo jumper placements, but it was an easy assembly. Stanton was extremely helpful in clearing that up. The power supplies are kits from the same vendor and are running at 34.5 VDC. Haven't hooked them up to major speakers yet but the bench boxes sound very clean, powerful and impressive. I'll report back after I do a full rig.

In keeping with the holiday season, I brought most all the siblings together for some cheer and happiness.

You can see the new Amp Camp from Nelson Pass, BPA-150 also from JA, MyRef V1.2 from Twisted Pear and Uriah Dailey and the MyRef Fremem Edition Beta from Dario Inserra.

Not shown is a pair of MyRef V1.3 from Siva Chander (linuxgurg), Two BrianGT amps from Chipamp.Com and the release candidate builds of the Fremem Edition. The collection represents an extremely enjoyable journey through DIY land. I have held on to so many in hopes to be able to do some real-time comparisons in a search not so much for the best amp, but for the one that comes closest to my perception of top shelf audio production

The only hole in the stable (for comparison) is one of the highly respected Pass F series offerings. Though not pure Pass, another F5T based build has been started.

So my winter months will be full and hours well spent (and ears probably worn out) in the search for "Audio Nirvana".

Best wishes to all for Happy Holidays, and thanks to everyone on all the forum threads for helping to make 2012 a very enjoyable and productive year. May 2013 be as good to all of us.

Forgot - this is a bit off topic for the thread but might be of interest to many. The new TDAs sound very good with this new and growing enclosure design.

I wish it were my build, but proper credit goes to dolphin123.
