  I usually listen to the CDs that are best mixed/mastered over the first couple days of any changes into the system.
  
  On all discs I've listened to, the background is more quiet, bass sucks, treble is recessed. I'll mentioned that cymbals are clean still, just pushed back into the mix more than I'm used to probably. Still, I don't want to have to think about the top, it should just be there.
  
  One thought that came to my head is that the ceramic v. glass has yielded the lower noise due to lower ringing of ceramics? I've read also that nickel is oft related to edginess.
  
  Other thoughts I've had are that the tube compliment (stock Chinese) aren't the greatest, and perhaps tweaking the fuses and revealed the weakness of the signal path. I tweaked the 12AX7 tubes with a tight wrapping of teflon tape, which really cleaned out the presentation of everything. This is quite an enjoyable tweak. Yet for $20-30, I can upgrade to any of a pair of Tung-Sol, Tesla, Ei, EH, Seimens signal tubes. Just gotta choose the best for my application.
  
  I've got some GiK panels coming on Friday. I know it will be a week or two of positioning and repositioning the panels and listening and re-listening, recalibrating the levels of the subbie before I'm used to that sound. Once I've got a knack for the presentation, I plan to either upgrade the signal tubes and/or the fuses to a gold-plated ceramics (if I can locate the Littelfuse 285s).

    Thanks, informative post. Herbies Audio Lab also makes nice affordable tube dampers. Their products have a 90 day trial - refund if not happy. Good luck and keep up informed. Have fun trying different tubes. It's like having Ravioli from different Italian chefs- no two are the same.

    Question "Authority", the mainstream media sucks - Go Independent and hold BOTH parties accountable instead of just the other guys!

    • Littelfuse Series 285, Gold or Rhodium Plate Ceramic Fuses - steven d 07:05:15 04/21/10 (0)

      DigiKey is carrying these for $4 a pop, but they are out of stock. All distributors are out of stock for these things.
      
      Was on the LF website last week and got around to requesting a sample of the 285 (datasheet on the link below). LF sends them out in 100 and 1000 packs. I'm thinking that I'll get a response from Littelfuse saying they are X amount for 100.
      
      Last night upon arriving home there's a package for me. Open it up and it's a FREE single fuse. Here's exactly what happened... On the 285 product page there is a 'Request Sample' link. When I requested the sample I entered '1' under quantity thinking I was sampling a pack of 100 fuses. I revisited the site and requested to sample 5 more gold-plated fuses and 6 rhodium plated fuses (yes, my integrated utilizes 6 time delay 5A fuses), let's see if I get another package in a week or so.
