Unused inputs?
Posted by: syd on 27 February 2003
Hi All
Here's an interesting observation. I got a Pioneer PDR-609 CD recorder a couple of day's ago and from cold it was so awful I could'nt stay in the same room as it, while I played a few Cds to warm it up. By the next day it had substantially improved and is still in the improving stage and sounds good on playback and does a good job of both digital and analogue recording. But the strange thing is since I connected it up the whole system has substantially improved. It is just so much more dynamic and listenable whether playing LP12, Micromega stage 5, Tuner or Tapes. I didn't switch the system off to fit it just had the preamp on Mute and plugged another power cable into my suffering extension. I was wondering if the fact that all the inputs are now connected up has had an effect. I know that it is recommended to remove unused boards on preamps for a small improvement, but this change is of the order that if I had heard it when comparing say a 250 to a 500 I would be out now robbing a bank for the cash. I know that Russ Andrews recommends "shorties" for the RCA inputs and that these were fairly common a number of years ago but I've never seen them for din sockets.
The only other explanation I can think of is that the weight of the pioneer on the Sound Org rack has done something to it or the fact that the 4 tier rack with glass shelves (layout is 250 bottom, Lingo and hicap next up, pioneer next and 32.5 on top. Previously had 250, lingo, Hicap and 32.5 on the 4 shelves) has become optimised with less areas of resonant glass. I'm unwilling to change anything at the moment ie. pull out some of the din connections in case the Magic disappears. I also can't believe that my mains supply has just decided to be perfect over the last two days or that the system at the moment of putting in the pioneer suddenly came on song.
Your'e insight into this would be well appreciated.
Yours in Music
