A little patience will be required if one isn't listed but look for a used, Rega Elex R. That speaker likes a little power are needs about 70w of good quality current to sound great. The Brio is a little shy of what you need in terms of power but will match brilliantly with the Kefs.
Best Integrated Amp (for me)
I recently upgraded to a Pro-Ject Classic turntable. I currently own KEF LS50 bookshelf speakers and a Nikko NR-719 tuner (from the 1980s).
I'm interested in upgrading to a better-quality (and nicer-looking) integrated amplifier to pair with my turntable and speakers. I love things that are really simple and classic-looking (but of course I also want it to sound great). I'm looking to spend somewhere between $500-$1000.
Any suggestions would be most appreciated!
