Best sounding Krell ?

Just installed Harmonic Technology AC15 2 meter power cable for my 400xi (thanks Darren!) and, wow, what an improvement over the stock cable!

Much, much larger soundstage and separation (wait that isn't, those aren't monoblocks is it, are they?) with increased height and depth. There is more "sweetness" to the timbre of naturally recorded instruments with greater dynamic range, even at low to moderate volume while listening to Vaughan Williams on Chandos. I have no idea why this works technically but this is certainly a major improvement.

Note to 400xi owners: please do upgrade your PC to at least an HT. As Daveb said, this does make a huge improvment. More comments later, for now I just want to enjoy...

Congrat's Stevecham on giving the 400xi a well deserved upgraded PC. As I've said before, most people are unaware of just how good the smallest krell is when used properly! Enjoy the music.

I currently have tried an XLO and Blue Circle PC and have heard little to no improvements on the Krell. Strange.

Lush,, try an MIT Magnum or higher PC and let me know what you think. I have an unused Transparent MM PC that you could have for a steal if you're interested (list $2000...sell it for $650). Interesting to note that other cable manufacturers are now getting on board the MIT train and putting networks on their PC's...Harm Tech, Purist etc..

I have been in this hobby for a number of years now...knowing what cables are exactly (tone controls) I have a hard time spending money which is almost equal to that of a component upgrade. For a bit more money (then the recommended power cables) I could simply turn around and buy a better amp i.e. SimAudio i-7, Tri-Vista, used Gryphon etc...
