Hello all, I'm Viz. I have a couple of 7B3 and I've just got a BR20, which I have to say I'm struggling with.
Turntable via RCA: no problem. XLR sounds really light, but my XLR cables are v cheap so I've ordered better ones.
DAC via digital coax: no problem.
CD player via HDMI: doesn't work. Apparently my Pro-Ject CD player's i2S output and the BR20's i2S input aren't compatible, which is really really annoying because I chose the HDMI option for this very purpose. However, through AES / EBU: no problem, sounds fantastic, even though I'm using another cheapo XLR cable.
TV via RCAs: no problem, sounds great.
iphone via wifi: managed to get it working today, took a bit of time. Sounds pretty good.
All in all the sound is absolutely fantastic, but it's definitely taking time to get it going well.
