Internal Amp Wire: Can it be improved?


I just picked up a pair of Krell KMA 100's which are of a late 80's early 90's vintage. Being a tube fan, im quite impressed of the Krells on certain types of music. My question is, that the amp is wired internally with Monster wire. Has anyone ever rewired the internals of the amp, or have an opinion on if I would see an improvement if I did the Krells. (any suggestions on type or Brand of wiring would be appreciated) thx

In our experience some of the early Monster wire corroded internally and over time caused problems (on the clear sleeved wire types this is easily seen as a "greenish" fungus). If you can, seek the advice of your local audio repair specialist and get them to check the wiring. If it is OK and you are happy with the sound of the amps as they are now, then leave well alone. You could spend a lot of money having the wire changed and not be impressed with the change. On the other hand if the wire is showing signs of internal corrosion you would be well advised to replace if possible. Hope this helps? Richard, www.vantageaudio.com
Richard, thanks for the info, as luck would have it, the MOnster in there now has coloured jackets and I cant see the wiring. The type of wire is the Monster "Powerline??" wire which from memory wasnt the best wire that was made. I was thinking or wodering what would happen with some good Cardas stuff.
Are you "handy" with a soldering iron....?? If you are proficient in electronics and feel capable and confident doing an upgrade yourself then I reckon you would notice an improvement with the Cardas wire. If you require any further info, etc give me an email. Good luck! Richard, www.vantageaudio.com
If I were you I'd contact Krell directly and get their opinion. They'll probably say don't do it, but be persistent and they'll give you some pointers/suggestions. I actually question whether the work is worth the potential sound quality improvement, but it you like soldering, who am I to say anything.
When you speak with someone at Krell, make sure it's a tech support person, rather than one in sales. Also if you rewire with Cardas, expect significant breakin time. You might also want to consider Kimber silver wire.
If you alter the electrical properties of the internal wiring, you might seriously impact the design relationships within. Unless you're an electrical engineer, or have Krell's approval, you shouldn't interfere with an already successful design.
whether you replace the wires or not, here's a cheap tweek. if the wires are currently bundled together to keep everything inside nice and neat, cut the ties and separate the wires abit (put some are between them as best you can given the space constraings). you may find a fuller more "bloomy" sound results.
If you do decide to alter the wiring, i would make a VALIANT effort at removing the original wiring as neatly and cleanly as possible. Label each wire individually, mark the direction that the wire was "flowing" and then make some type of chart to show what goes where. To make all of this a lot simpler, pick up a "wire labeling kit" from www.mcmelectronics.com BEFORE you start this or a similar project. While you may be able to alter the sonics more to your liking, keep in mind that the equipment was "voiced" with that specific wiring. Should you not like the wire that you install, you can now go back to the original design with minimal impact or loss of performance. You may find that changing only specific wires in certain areas are of benefit. Good luck and hope it all works out for you. Sean >
thanks to all for your input, I am leaning towards, if it aint broke, dont fix it.
Rich I'm surprised you didn't mention the mod guru guy Andy Bartha. If anyone can do this job right he can, & would have a conception of the right wire to use for the application. Andy's address = 4680 SW 74th Terrace, Davie, Florida 33314 Ph# 954-583-7866. Different wire will voice differently though, so some experimentation would be in order. Strongly agree with the thorough identification of each conductor's direction & placement, just in case you need to go back. I used the same approach when rewiring speaker crossovers. Sounds like a fun project to try...
