I have a 20 year old Kodak Photo CD PCD-5850 player that holds 5 discs. It plays CD's fine but I thought a new Denon DCD-600NE CD Player with AL32 Processing might sound better with the Hegel H90 integrated amp and the Vento 9.2 Reference DC speakers in my office. When the Denon player arrived I set up an AB test.\n\nHere's the test configuration:\n1. Kodak PCD-5850 on analog1 on Hegel H90\n2. DCD-600NE CD Player on analog2 on Hegel H90\n3. DCD-600NE CD Player on Optical1 of Hegel H90\n\nNext, I put a copy of Nils Lofgren Acoustic Live CD in each player and started both players so each was playing at the same counter number on the same song. I switched between analog1 and 2 on the H90 expecting the Denon to sound better. To my surprise, the difference was non-existent to super minimal. Is it possible CD players don't offer much difference in sound? Is this similar to me not being able to detect an audible difference between my Adcom amp or the Denon 4500 powering my VMPS SuperTower III mains?\n\nNext, I tested between the analog1 and optical1 on the DCD-600NE CD Player. I actually, heard a little more clarity using the analog outs than the optical out on the same DCD-600NE. If I use PURE DIRECT mode 2 it turns off the optical port. PURE DIRECT Mode 1 leaves it on.\n\nWhat I'm coming away from this is a good CD transport hooked up to the the H90 sounds good with either source. If this holds true - why would someone spend $1,000 on a CD player vs a $300 unit?\n\nHas anyone else AB'ed their new CD player to see if they can tell an audible difference? Thank you!
