I have used the 401hr w/o my subs. Overall the 401 hr is a balanced amp from top to bottom. It satisfies my need for speed. I recall puting on a piano album. I had to check to see if I had left the turntable on 45 instead of 33. It has an uncanny ability to recover from each note no matter how demanding. There is no image collapse when the music gets loud. It has the abilty to display each instrument in space from front to back and side to side.
The funny thing is that many records where I thought the singers were muumbling now come through as articulate and easy to discern.
I think it is an excellent amp for cls in particular and panel speakers in general.
I have not done any tube rolling or experimenting with power cords.
To my ears this amp falls in the category of you will not know there is anything better until you insert it into your system.
I have only two complaints. As pretty as it is I wish there was a switch to turn the ligth off completely. I also wish the front panel had some way to prevent the front panel from slamming against the shelf when it is pulled down.
I have no financial interest in the company.
