Hey guys,

I'm about to build my first DIY Amplifier to power a pair of passive (LXMini from Linkwitz Lab) and I'm having a hard time deciding between these two based amp. (I'll Need Channels into 8 Ohms with at least 50W continuous)

Setup 1: TAS5630
AMP: 2x Sure 2x300w TAS560 --->https://www.parts-express.com/sure-electronics-aa-ab32191-2x300w-tas5630-class-d-amplifier-board--320-309
PS : 1 or 2 Mean Well 48v 350W ---> http://www.parts-express.com/mean-well- ... --320-3143

‚Äč
Setup 2: IRS2092
AMP: 2x Sure 2x240w-IRS2092 ---> https://www.parts-express.com/sure-elec ... d--320-313
SMPS: 1 or 2 Abletec smps ---> http://www.ebay.com/itm/Abletec-900-Wat ... xySfBR7ZTP



Which is a better setup? I'm hearing that both TAS563 and IRS2092 are good. And the IRS2092 are sometimes compared to the Hypex UcD 180 series since both are self-oscillating amp. So that's pretty re-assuring of the IRS2092. Hypex, maybe one day!

Seeing as both of these setup are similar in clost, IRS2092 might be slightly cheaper with the albletec SMPS. Any opinion would be appreciated!

Thanks!

I have built and sold a number of Ds lately. I always use a linear PS. Personally I wouldn't go with SMPS but many do and love thier amps.
