Please Post any Specs that you can on this...Do they need any Beta Testers? Count me in... I checked the Sure Site and there is no mention of this.

Interesting!... can't wait to hear your feedback on the new board.

I am very much enjoying their 2*100W version at the moment and hope the new board carries the same sonic quality of the 2 channel version.

I wonder if I can combine this new board with my existing 2*100W one in a 5.1 home theatre configuration.

Looks good but I think that a fan would be needed. Looks like the chokes should have better power handling too. Keep us updated but I suspect it will be on ebay soon.

hi,sled108
I also don't find the link in the Sure Site, but their salesman Robert send an introduction:
the size is 144.8 (L) X 134.6(W) X 31.0(H) ±0.2mm, and they use two TC2000 and four TP2050 chips from Tripath,power supplies ranging from 10V-30V,and the amplifier has four channels, all with the same power up to 100W each and sound quality.
but i don't tesify it. so i would buy one at first and tell you my feeling of it.

Interesting, the layout looks similar to the old 4*100W. I hope it doesn't suffer from the same high level noise floor. if it's anything like the 2*100W though it won't!

Can't wait to see more details.

I would swap out the 2 4x100 amps I got from them prior for a pair of these beasts if they were up to the same specs as their current 2x100 offerings. The noise kills any chance of using them in my HT (which is a shame since i've got 3 boards sitting here for a total of 12 channels up for use).

Default Hi I am back

Been away from the forum for a while. But I will be easing myself back into audio building over the next few weeks.

Just got hold of the 2*100w amps. I am very impressed with it so far...

http://www.justblair.co.uk/sure-2x10...pressions.html

I have written an article, but it possibly needs a little tidying up

I have also been speaking to Robert Lee and should soon have my hands on the 4*100W board that they are bringing out. I will post as soon as I have had a chance to listen to it.

The stereo board is pretty damn good. A step up from the TA2024 boards that i have played with.

A little strong on the mid-range, but very clear, very detailed, very fast. I think I may be in love with it already after only 8 hours of listening time. I will try a few mods on it next week.

Justblair,

Read your article on the 2*100W amp from Sure Elect., might it be a little long. I agree this amp is a bargain at this price.

I bought a pair as well and modified in accordance with the post 352 from this thread:
Sure Electronics New Tripath Board tc2000+tp2050

I think there are a few Additional mods you can still do to this amp that will further alter the sound reproduction on top of what I have done.

1. change the feedback resistors(to resistors from Vishay other brand) on the TA2050.
2. from Audio1st, change the caps on the 5V regulator to tantulum type.
3. output inductors and caps, I am not so sure?

What do you think, and any more ideas? With all these mods I think it will rival the Virtue Amp One/Two that is based on this chipset.
