One feature I wish my Cayin A88T mark 1 (16 ohm taps) had was external bias meter and adjustments.
I use my Vintage Preamp’s many features that are missing on most modern integrated, so I only use 1 input and remote volume/mute of the Integrated. If no preamp, I would want remote balance and a Stereo/Mono Mode. If balance is remote, that’s a wonderful feature to tweak a track, just a little can make a big difference.
If you can bridge it for Mono, you have the option of doubling your power IF you find some inefficient speakers you love. Just an option you may never use.
