Default PS for a MKII tripath TA2024 Amp 2x15W

Hi there
Just got my tripath amps today, and cant wait to get them working!
now i need a powersupply.

ive found this
HN-POWER HNP18-120 PLUG-POW. SUPP. 18W | Mains Adapters with Fixed Voltage Mains Adapters / Power Supplies Power Supplies & Mains Adapters Batteries/Power | Conrad Electronic SE - Mains Adapters with Fixed Voltage

and this
Voltcraft FPPS 12-12V 18W power supply | Mains Adapters with Fixed Voltage Mains Adapters / Power Supplies Power Supplies & Mains Adapters Batteries/Power | Conrad Electronic SE - Mains Adapters with Fixed Voltage

The reason im asking is that, ive read here on the forum that the PS is important considering soundquality, and i really wanna get the best SQ i can!

So do you think one of these PS's will do or can you recommend something else?

Best regards
Andreas

If you want the best performance from this chip you should stay below:-

6W into 8 ohms on both channels

10W into 4 ohms on both channels


If your speakers maintain 8 ohms and you stick to 2x6W then the linked to power supplies should be OK

If the speakers are 4 ohms you need a 30W output power supply

If you want max output into 4 ohms you will need a 45W power supply.

PS this information i have gleaned/calculated from the data sheet , i have no hands on experience with this chip .

I'm powering a TA2024 amp from a "brick" 12V 3A Polaroid power adapter that I found in a gravel pit (probably from a scanner or monitor). I don't hear any audible noise. I've picked up similar adapters from thrift stores for a few dollars each, and a couple of Xantrex 12V/5A from a liquidation store that were made to power thermoelectric picnic coolers. Or search eBay for 12V (3A,4A,5A) supply and you'll find some for under $10 shipped. Thrift store supplies may be higher quality since they were originally purchased by companies with reputations.
