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.

The HK X30 receiver series seem to have become classics. I have a HK 430 and it is wonderfully musical within it's more limited power range. Word was when they were current products that Robert Fulton consulted on their design.

One word of caution on the Citation 12 amp for anyone considering that. It was very good into an 8 ohm load but not happy with 4 ohms. I used one with a single pair of Advent speakers in the '70s and all was well until I decided to try a Double Advent system -- the amp failed soon afterwards.
