Hegel H590 with BW 800D

Thank you for the responses.  It's helpful to get some additional perspectives.

In my research, I see a lot of posts about how these speakers play very well with various mono-block setups with 600+ Watts per channel (e.g., MC601/611 or Classe CA-M600, etc.)  Which made me wonder how much I would be "leaving on the table" by using an integrated like this (with "only" 300 Watts per channel.)

I haven't had the privilege of hearing these speakers with various different amps, so have no idea how much of a difference we're talking across different amps. 

I was using a Classe 2300, which is a stereo amp providing 300 watts per

Channel  at 8 ohms, and 600 at 4 ohms.  It drove my B&W 803D3’s fine.  

What amp are you using now, and what kind of improvements are you looking for?

There's a good chance the 390 would drive those speakers without the benefit of a cable!  Enjoy!!

A related question to the H590 -- I just realized that it doesn't have a headphone output.

Is there a clean way to utilize the DAC/pre-amp on the device with headphones?  My concern is that feeding the variable-output/fixed-line output from the H590 to an external headphone amp would leave the speakers in the H590 on.  Does anyone know if "muting" the H590 will leave the variable-output/fixed-line outputs active (there by allowing me to mute the speakers while still driving the headphone amp.).
