My current equipment: Harman Kardon AVR320 receiver Dahlquist System One (due to room limitations had to get sealed-enclosure speakers) Denon DCM-360 CD player (rather exciting-sounding changer compared to the venerable 370, with "alpha processing" versus the rather buttery Burr-Brown DACs on the 370) I am currently trying to buy a DVD player. Video quality is _almost_ secondary, as I only have a 24" flat-screen Panasonic 24SX11 TV, due to the wall unit limitations. However, I DO want to get into at least one high-rez multichannel sound format, and expand my library of those. So, I'd like to get as much audio performance as possible out of the rig, up to the AVR320/Dahlquist limitations. My choices: Pioneer 45a (new) - $475 + tax local, $390 + S&H on the 'net. Pioneer 47a (demo) - $600 + tax local (Not the 47ai) I'm thinking I could talk them down a bit on that. Denon DVD-1600 - $475+ tax local, don't know about online yet Panasonic RP-91 - $470 (online dealer demo) I like the Pioneer units because of the shuttle control on the remote. Gimmicky high-tech stuff, I know, but it appeals to me. Also, they play SVCD's (I have a fair collection of Russian-language software on SVCD), and have both SACD and DVD-A capabilities. The salesguy at Magnolia Hi-Fi said that the 47a's main advantage was a "copper chassis". Any explanation of the benefits of that would be much appreciated. The Denon has an unspectacular remote, but is made in Japan. However, it has no SACD output or coax out, so the coax cable I ordered from Marc at audioshop will go unused The Panasonic I know very little about, as I was considering it, until I found that demo, to be a little too high end for my budget. If it can do wonderous things with DVD-A's, and can beat the D/A converters on the HK (so I don't use it as a transport), I'll definitely consider it. Thanks for any responses!
