I also got some steel cabinets to house mine, so I'd better get going on finishing these off for my basement system this winter! With a 100 db/Watt Tapped Horn "OThorn" sub and some Peavey/JBL/K402/DaveA LMAHL tweeters, this will be a killer "basement system" in my workout room in the basement.

DizRotus Posted October 14, 2020 Share Posted October 14, 2020 I use mine to power “Supered” HIPs. A TPA3118 “Wiener” class D amp powers my DIY Fostex 103 bass reflex single drivers. While both sound very good, the TPA3255EVM sounds better than the 3118 on the same speakers. Some of the difference could be attributable to the higher power of the 3255.

Shiva Posted October 14, 2020 Share Posted October 14, 2020 Is this comparable, as a finished item? https://www.ebay.com/itm/Finished-HIFI-Digital-TAS5630-Stereo-Amplifier-Class-D-Amp-300W-2-AD872-Preamp/293622715777?hash=item445d471581:g:rpQAAOSwGf5d3kmu Quote Link to comment Share on other sites More sharing options...

It's a great indication of Chinese vs. US using the same chip and PCB components, and you get a case with it...............but no power supply. The 24-38 volts suggests that it should reach the 300 Watt range if you use the higher end of the supply range. If you use 24 V, you'd be lucky to get 120 watts/channel with a 4 ohm load. 1 Quote Link to comment Share on other sites More sharing options...
babadono Posted October 14, 2020 Share Posted October 14, 2020 Still waiting.......somebody please measure the residual carrier (450KHz) that you get at the output of yourTPA3255Eval board amp. I reported in my thread I'm seeing 1.5 to 2volts p to p with the output filter supplied by T.I. on their board. Using my amp on the Jube Bass bins so I don't hear any artifacts but just curious what others are seeing. Quote Link to comment Share on other sites More sharing options...

Don't forget that in order to see that kind of power your PS also needs to supply around 9 Amps ... per channel. Quote Link to comment Share on other sites More sharing options...

I also believe that so many amps today can work off so few smaller devices because the Rds On of modern Mosfet transistore is usually 0.1 ohms or less.

Where's the $75 or even the $150? Ended up picking up two 1000ASP ice amps at $249 each from PE. Wish they could come up with their cabling. It's been on BO.

Ice amplifier and a housing kit. Had to order 2 sets of cables since they were incomplete. Cables for that is the issue and even now, the connector is missing from one of the AC inputs. Stupid crap....................on the other hand, the 2 Hypex mono bloc kits I ordered from the Netherlands came fast, complete, and were the easiest builds EVER, with no soldering. I did both in 1.4 hours flat! Quote Link to comment Share on other sites More sharing options...

When I heard them vs. my First Watt Aleph J reference amp, it was not contest. Class A sound with 400 watts of headroom! BTW, I never turn them off since they use so little power left on. You can do it without fear. Heck, I'll by 'em from you if you don't like them! Quote Link to comment Share on other sites More sharing options...

I should get them by Thankgiving, so I'll let you know...........now to look for a suitable power supply! Looks like the Mean Well HRP 600N-36 is the ticket!

I was wondering what the right power supply would be to bring that amp to its full power. Quote Link to comment Share on other sites More sharing options...

The power supplies are more money than the amp.........BUT, I may be able to use an old amplifier that needs repair, which has a supply that would work.

They are incredible amplifiers. 1 Quote Link to comment Share on other sites More sharing options...
