Krell KAV 250 A

how do i "disconnect the signal links so that i won't drive the 300i amp stages into an open load" ?
when the time comes of course...
also, isn't the stock cable from krell good enough? its pretty thick (i'm not a big believer in spending money on cables, i know u might disagree)
btw, i'm using nordost blue haven as speaker cable for my wonderful talon khorus set..
i believe i can find a used kav 250A for about 1500 but what if i could spend up to 3000 on a better amp, will it take me to a whole different (higher) level or the difference would b to subtle to b worth it? any recommendations?
thank you all for your kind help.

If you really enjoy Krell, another suggestion might be to rid yourself of the 300i and get a 500i. The 500 is a monster compared to the 300 and should power the Talons with ease. Once you get the 500i in your hands, you'll realize its a much different animal.

Reason I suggest this is I don't think its reasonably easy to use the 300i as a preamp only. The 300p is used for that purpose.

Bryan certainly makes a good point. Not being familiar with this 300i piece myself I don't know if in fact there are outboard connectors that allow separating the preamp stage from the poweramp section; in fact these connections may not even be available at the rear panel, but only inside. I had previously checked on Krell's website, but I don't see it shown there.
Certainly any stock power cord will allow a component to play music, but not at its' optimum by any means. Just stick with whatever you're comfortable with for the time being; I only mentioned this because if I had kept my 250a & tried to tweak it with better cabling, then I might not have ever sold it. But I didn't believe in any of that "nonsense" either at the time, & probably made a mistake due to my ignorance.

This is just something to think about, you have a $15,000 speakers I suggest you sell the 300i and buy an FPB series amp (since you like the Krell sound, so do I mind you) and a very good tube preamp. Then you'll hear what your speakers can really do.

here's another issue: was thinking that if the 300i does not externally link its preamp output section to its power amp input section, then you have no external access to variable-level preamp output to drive an external power amp anyway. You cannot use the tape monitor output (even if available) because it runs at a fixed level, but you need variable of course.
