The phase button on my Rowland Capri is for...?

Did he put it there to drive me nuts? On some songs, turning on the phase button sounds better, other songs worse, and others no difference. And the differences between all 3 are extremely subtle. Maybe a slightly wider stage, maybe a little more bass...or the inverse. Or nothing.

I am running a Benchmark DAC1 via balanced outs to the balanced ins on the Capri preamp, and balanced outs from the Capri to the balanced ins of my Rowland 102 amp.

I have read that Rowland uses the "old" method of balancing...whatever that means. I have also read that the Benchmark DAC1 is not "differentially" balanced.

I have no idea what any of this means. But I do find it somewhat irksome that pressing the phase button is so unpredictable.

Could anyone please explain briefly, in Best Buy terms, what all this means, and if the Benchmark is in fact playing nicely with my Rowland gear? The sound is pretty phoenomenal regardless. I'm more curious than concerned. In my crazy brain, seeing the orange light on the phase button makes me feel like I'm not listening to the sound in the purest form, like seeing a bass/treble knob not zeroed.

Thanks in advance for any shed light!
BTW Rkny, what do you think of the Carpi? What did it replace? What amp is it driving? Do you have the phono section in it? Are you using the PC-1 Power Factor Correction in front of it?

Dcstep - I have the Capri (w/phono), 102 and PC-1. I'm very pleased with it all. I can't characterize the sound for you but I will say that Rowland is for grownups. It's elegant, convenient, quiet and ergonomically sound. Very pretty too.

When you decide, as I did, that you've had enough of compromises and irregularities, JRDG is a welcome change for the better. It feels like it will last forever.

I'm driving Zu Presence speakers.
Agree with Macro 100%. I am only running the Capri and the Rowland phono, no PFC. My sole source is an Apple TV via Benchmark DAC1. I ignored everyone's warnings that the digital music would be the weak link. The sound is simply phoenomenal.
Thanks Macrojack, I grew a long time ago, but I understand you attraction to the Capri/102. I've got the Continuum 500 and I'm adding the phono stage on Monday. It's an incredible amp.

Hi Rkny, my current hi-fi setup is like this: Mac Pro -> Benchmark DAC1 -> Rowland 102 amp. I am now considering whether should I buy the Capri preamp. As you have the similar setup with mine, I would like to seek your opinion on whether the Capri preamp do a difference on sound performance in such equipment setup?

Thank you very much in advance.
