It's not the sound I want!

I agree that the source is the most important. Try something like a Meridian 508.24 and the improvement will amaze you.

I'd echo much of the above comments primarily because I found myself in nearly the same position--and there was no mistaking that the "cure" was a new CD player. I had managed to scrape together some Thiel 2.3's, and Bryston 4B-ST amp, and a VTL pre-amp (my first dabble with the tubes), but was making it all go with the help of nothing more than a decade-old Yamaha changer (which is, admitedly, a whole lot worse than your Adcom). Nothing doing. Trouble was, I was REAL tired of spending money, and was just looking for an adequate CD player that would give the rest of the equipment a chance to shine while I got over the horror of realizing how much I had already spent (even buying used). By that time, I was also pretty infatuated with tubes, so I started looking at playeres from the likes of Cal Audio, Jolida, et al. By chance, I stumbled on this AH!Tjoeb retrofit sillyness which is based on a not-so-special Marantz player and then essentially gutted and re-tricked out with all of the latest fancyness and a tube stage. (for an extensive litany of praise, check out audioreview.com) Well, I bought one, pretty much on a whim (can only order them from the factory in Holland or from a fellow named Kevin at Upscale Audio in CA, check out thier website...). Truth be told, if you have the will to invest in a Wadia, more power to you--I wish I owned one myself (or Levinson, or Meridian, or Linn...). But I've found that this little (ugly) tubed retrofit has hade me happier than I imagined it could. I had planned on it being essentially transitional when I bought it (yes, had to buy it unheard, which was tough, but they're only around $550 with all the options...) but I suspect that I'll end up hanging on to this one for a while. Maybe it's not your bag (maybe you should just sell the farm and go analog) but I would strongly suggest that it is worth a consideration. Best of luck, Peter

I hate to jump on the band wagon...but the Adcom is not the best choice. I would also say that the Krell, in my opinion, is not a very good amp either. Hyped, yes, but it's performance leaves much to be desired. I know that an integrated helps shorten the chain and lessens cost, but how about selling both the Krell and the Adcom and use the funds along with a bit extra(less than adding a DAC to the Adcom), and look for a good quality neutral amplifier and find a used Wadia 830 (former class A component, recently discontinued) and going direct connect, using the variable out of the Wadia for pre-amp functions,if you are a single source person. There are a number of reasonably priced used amps out there by CJ, ARC, Pass, ETC. that would make your promising system really sing!

I would go along with most of the previous advice about the CD player, most people who go on and on about digital sorces have never heard a good CD player. I would recommend you audition a CAL Labs. If you have the bucks check out the 15 or 20, the 20 is expensive, but is also a great DVD Player. If money is an issue, try to pick up a older Cal Icon Power Boss used. I would take issue with the previous advisor and advise that before you 86 the Krell 300i, wait till you play a good CD player through your system as it now configured. I use a CAL 20 thru a Krell 300i as kinda a second system and it soulds great with several different speakers I have tried (Soliloquy, Magnepan) I do also have some B&W speakers and the Krell can sound a little bright thru them.(Remember the 300i is also a Stereophile class A rated unit) It just may not be the amp for the speakers you are using or the speakers you are using may not be suited for the Krell. I have no experience with Areiel's. Bottom line, get a good CD player, and if that does not float your boat, then it may come down to getting a new amp for your speakers or getting new speakers for your amp.

After all the advice you've gotten, most of which sounds right to me, I'd just add: look for a used Sonic Frontiers SFCD-1 one-piece CD player. It has a tubed output stage, and impressed the Stereophile people, including Atkinson, before it got more or less forgotten as other "flavors of the month" came along. And it's a lot cheaper than a Wadia 830 on the used market. Of course if you can afford the Wadia, few would deny that it would be a better choice.
