I'm planning to change my old DIY amp

Velleman nv

with a class D board, keeping the box and the PSU. The PSU is a 2 x 32V DC and the amp will power two 30 cm woofer 4 Ohms impédance, 91 db of sensitivity in a 25 m2 room.

I've seen two interresting products :

Sure 2 or 4 * 100w TK2050 cards
Hifimediy T3 or T4 TK2050 cards

Wich one is the best choice ? Any advice welcome 🙂

First thing i've seen, level of the PSU for Sure card seems to be on the limit of the specs.

TK2050 is excellent IMO.

Judging only from what I've read: The Sure boards don't use very good components, they're not the ultimate in reliability, and they run too hot for me to trust them. These chips are supposed to run pretty cool. I would go for Hifimediy.

That said, many people on the forums love their Sure amps!

(I like 41Hz best of all, myself, but they only make prebuilt TA2020 and TA4410 boards. The rest are unsoldered kits.)

I have very briefly auditioned an UcD 180, and it was pretty great. From this very limited experience I still prefer the TK2050, but any of these will be pretty great. Both TK2050 and NCore are very accurate; The Tripath speaks more to me musically. But I only had 5 minutes with the NCore so I can't say. Basically, you can't go wrong with either of these amp types.

Note that there is a new UcD design evolution coming out from Hypex very soon, in December I believe, the NCore 400. It's probably worth waiting for that one if you're looking towards UcD gear.

(Hey sorry, I didn't really notice that it's for a sub amp ... I'd go for the Hifimediy T3. The difference in "flavor" doesn't really apply as much to the bass with these amps, and the paralleled TK2050 as in Hifimediy T3 makes some of the most fun bass I've heard. Very cost-effective, too.)
