HK 730 Twin

No problems. You're just doing what your ears and common sense is telling you to do. See here (I hope its OK to put link )

Yes that is true about the ears, It just sounds so lush and open. In comparison to my B&K ST-140 amp there is no comparison. The HK makes the B&K sound irritatingly harsh and super bright.

I use a Harman Kardon Citation 16A amplifier. I have never heard better. Used to have a very elaborate Mac set up, but it couldn't compare with the spacious sound of the Citation. Personally, I always hated Harman Kardon products, (for no apparent reason) so this was hard for me to swallow. But I am glad that I did. I use the 16A with a Citation 17 preamp and love it. This is my system for life. Old school and vintage to be sure, but so sweet sounding. You might try an HK/Citation 12, 16 or 19, as they are similar to your 730. The Citation gear was all hand made and used the finest available components. Enjoy.

I have an HK 930. One of best solid state receivers of all time. Nothing out there like it today.
