I finally got everything built and hooked up and spent some time listening this weekend. The second post has the rest of the pictures.
First what I listened to them with.
The power goes through a APC H-15 voltage regulator\conditioner. A Mac C-39 preamp, going to a Rane AC-22 electronic crossover and then to a Mac MC-275 tube amp for the highs and a Mac MC-2205 SS amp for the lows. The speakers are Altec Lansing Valencias.
The players are the following in order of date of manufacture. Roksan Kandy MKII 2005-6, McIntosh MCD-205 2003, Denon DCD-1650AR 1999, Denon DCD-2560 1990, Sony 707 ESD 1989, Denon DCD-3300 1987 and lastly a Yamaha CD-1 1985.
Everything is connected via homemade interconnects using Canare Star Quad cable and Canare F-10 connectors. The players all have the same length IC's and the 5 on the rack run through a Russound source switch so they are equal in that respect. The MCD-205 & Denon 1650AR both are direct to the preamp. I switched them around and couldn't hear any advatange over the direct hookup VS going through the switch.
I used 7 CDR's of Mark Knopfler's Screenplaying. As it has a wide variety of music on it. I set the outputs as close as possible with a SPL meter and sat down and listened.
Now for the disclaimers, The sound probably varies more so with the older players as age and use take their toll. Also I'm well over 60 so my hearing isn't what it once was. Also this is not a brand A VS brand B comparison. So there will be no model X wiping the floor with model Y. Just differences I hear or perceive I hear.
The first thing I noticed was the highs are more pronounced on the older players. Which is not to say the newer machines roll of the highs but rather they do not stand out from the rest of the music like I hear from the older players.
I would not have a problem listening to any one of these machines if it was the only one I had. The better bass came from the MCD-205 and the Sony 707, followed closely by the Denon 1650AR & Denon 2560.
Soundstage, imaging and detail are far more dependent on the quality of the recording rather than the machine.
These players are not all TOTL models but they aren't entry level either so the build quality is good on all of them.
One thing I had wished for but didn't happen was to have others here to isten and make notes of what they heard. If you know someone who is of the opinion that only new SOTA DAC's can sound good, send them my way.
I think that idea that older players can't possibly sound as good as newer units is pure hogwash. Especially when the transport on some of these weighs more than the whole Oppo or Toshiba offering of the month.
I'm a lousy photographer as you will see. You can get the general idea of what is what from them though.
