I have a Denon DVD-A 3300 for DVDs and the TRL modded Sony 777 for redbook & SACD. So only one shelf instead of 2.
I have tested my 777 with my friends Audio Research DAC 7 and I was surprised how well the TRL 777 did. The DAC 7 had a very slight edge in smoothness but no difference in detail, air, soundstage etc. So I got the bug to maybe change up the system and rack, and possibly one less shelf.
