Hear sibilance on Krall, Famous Blue, D. Fagen?

Bill_k:
Much more on the digital side; not really noticing it very much on vinyl.

No metal dome tweeters anywhere near my rig! ;-)

Bill,
No offense taken!

Almarg,
Thanks so much for your ever-helpful posts. I have a Signal Cable power cord on loan from a friend but hadn't yet tried it on the DAC because my stereo cabinet only has a puny hole for running cables out the back and I'm not sure the beefier cord's plug will fit. But now I'll have to give it a try.

Jea48,
Wow, thanks for all that research. Since I'm bypassing the CDP's internal DAC, I think I'll try a better cord on the DAC first, but I'd never seen Roy Hall's comments on the stock power cord, so that's very useful.

Zd542:
Yes, my system page isn't up to date. I've sold my Ref 3A De Capo's and I'm on a hunt for speakers that may be better suited to my new SET amp.
I am currently breaking in a new pair of speakers. I'm not getting more specific on make and model because this is from a small manufacturer and I am sensitive to not putting negative comments on the Internet that may have more to do with my ears and system than the product itself. Also, they're not fully broken in yet and I'm still futzing around with the positioning.
I'd never heard this sibilance before and I'm trying to figure out if it's coming from the speakers or somewhere else in the system. Or maybe that's just how those tracks were recorded.

Also, FWIW, the Warnes FBR is the Cisco gold 24th Anniversary CD with the extra tracks. On Steve Hoffman's forums, some seem to love this version and some find the remastering a little harsh and sibilant! ;-)

Ironically, I don't particularly care for the music on either the Warnes or the Krall, but since they're audiophile warhorses I thought they should sound good. :-P

Hi, Brownsfan,
The Kit 1 does use a 5U4G rectifier as standard, but my rectifier tube and the 300B's were backordered when my kit shipped, and when the tubes came Brian Smith was nice enough to substitute a 274 B tube as a substitute, which does sound better than the stock 5U4G (which I've also had a chance to try). It doesn't mean, though, that a better 5U4G wouldn't help. Thanks for the tip.

Jea,
I had two Signal Cable power cords and found a way to thread them backwards into the cabinet and connect them to both the DAC and the CD player I'm using as a transport. I believe that the system sounds better - more solid bass, especially, and "cleaner" overall - but the harshness is still there.
I'm beginning to think the speakers need more break in, but we'll see and I'll try some of the other suggestions here and report back.

Jea,

Thank you, and very interesting, indeed!

I listened to the track again today. All is well until she gets to the word "soon [we'll be without the moon…]." The letter "S" in the word "soon" is very strident. I'm not sure why.
