WOULD LIKE TO RECABLE LOOKING FOR HELP

I agree with the above statement that cast is not that great compared to good balanced cables. The best I can say about cast is they are relatively cheap. I compared many cables in my Krell system (no longer own). My favorite match were a pair of signal cable balanced cables (not the silver). My KCT and 400cx were matched with Nautilus 802s. The signal cable tamed the edgy Krell gear and gave me the best bass. Cardas Golden Reference were the most expensive I tried. BTW a hugh upgrade for your HRX is a Triplanar tonearm. I still can't believe the difference it made. My cartridge is a ZYX Universe. I can't speak to any other cartridge. It basically gave me better everything. Email me your number if you want details.

this is an open ended question. what type of presentation are you trying to achieve. cables are a lot like people they have different personalities. what is your favorite ?

like i said i listen to rock on VINYL, tend to play it loud, like to feel the music. i have considered synergistic, very pricey. just not sure you get your $ worth or just think you have to spend a lot to get what your looking for. 800d's list $20,000.00 the absolute ref list for$8,500.00(10ft). seems insane. after dicount synergistic, higher disc., 38% of cost of speaker, tough to swallow. any informed advise?

Generally speaking you will get more performance for your dollar by upgrading the system's weakest component as opposed to putting the money into wires. There are exceptions of course.

Depending on your available funds, I'd think about upgrading the tonearm as mentioned previously. Consider a Schroeder and Dynavector in addition to the TP.

Even in mega buck reference systems, I'm not real keen on $8500 wires. You will find folks who disagree.

How do you like the Krell 600s? Have you had any Krell monoblocks before? If so, how would you characterize the difference/improvement?
I currently have the FPB 450Mcxs, and was thinking of upgrading to the 600s, but so far haven't found anyone who's actually heard them.
