Default 4 x 50 watts for Linkwitz LXmini - suggestions?

Hi,

I am about to build a pair of LXminis and since the Emotiva UPA500 is discontinued I am interested in other options that won't cost a lot, but still sound VERY good and provide enough power to drive the LXminis safely. I prefer modules og ready-made stuff over too much soldering.

A pair of TDA7498's will give you 4 x 100w for ver little money. They sound quite good and are worth considering. Need a 24v power supply and you should get 50w of low distortion pipit no problem.

Ok, and SQ will be on par with e.g. Emotiva?

I don't know about Emotiva but SQ is comparable to TPA3116 which is very good as class D amps go. I don't bother with cases for DIY. But plenty of options for cases.

If you want a cased amp, better off buying a complete finished amp from China, Aliexpress, eBay, etc. you will not save any $ doing it yourself.

For example $57 complete. No way a case, knobs, binding posts etc can be made for less on your own.

Ok. Thanks. What I really want is a poweramp without volume etc. but I probably can just leave at full volume and adjust upstream.

Hi JOHNNYCR100,

Surely a good amp but at 260 € for only the amp PCBs I think there is a lot of alternatives.
I own a player wich has an Icepower 50ASX2 amp module inside, it sound VERY good. Why not use two pwr-ice125WD plate amp :

That is perhaps the finest sounding amp ever at any price. If you can afford it and have time to hand solder that is great. It doesn't hurt to spend $30 for a pair of cheap TDA7498's that are 90% of the way there to get started and for tryout.
