I was going to mention Linear Power, Butler and Tru Tech. If you have a minute to look up Tru's Facebook page, they post a lot of production photos and some videos. They posted some pics of their Billet amps in a polished piano black finish that may be the most beautiful amplifiers I've ever seen. Pricey? Absolutely. But, then again they aren't a SPL manufacturer. Geared more toward the SQ or SQL buyer.
And if you can't afford new, you can always buy used. But, if you do, try to get gear that has been well cared for. Older amp components may need to be replaced and that can cost big $$$.
