Which worse- long I/C of speaker run


Musical Fidelity had their new M250 power block amplifiers. Their pitch goes that the amp is close to the load (speaker) so to "give the amplifier excellent damping".

But this will require long 2-12 foot runs of I/C. So which is worse? Long runs of speaker cable or interconects? Will the delicate low level signal be losing information with a long I/C.

I would think the preamp would require full balanced outputs (preferably all the way through the preamp - Mike Creek was displaying such a preamp) to prevent signal loss.
Any thoughts? Thanks

I am of the belief that you are better off with short interconnects and longer speaker cables. That is, so long as the speaker cables are of a low impedance design.

Since most speaker cables are not designed correctly and don't offer this "feature", using shorter speaker cables can help alleviate some of the distortion and colouration that the speaker cables themselves are introducing into the system. Using such a set-up also takes into account that you would be using interconnects of high quality materials and design.

By high quality, i am talking about something with reasonable impedances and a design that lends itself to natural RFI and EMI rejection i.e. heavy shielding, braiding, twisting, star-quad, etc... and other similar geometries. Since it is easier to achieve such designs with smaller, less expensive conductors like those found in interconnects, i would not doubt that going the long interconnect / short speaker cable length is an improvement in many systems.

HOWEVER, If one were to simply change to speaker cables that were properly designed in terms of having a nominally low characteristic impedance, one would be able to achieve improved power transfer and coupling between amp and speaker. In doing so, the results of shortened speaker cables would be far less drastic. Then one could go back to using shorter interconnects, which will ALWAYS minimize signal loss and signal degradation.

If you want to find out how "good" or "knowledgable" a cable manufacturer is, ask them what the nominal impedance of one of their cables is within the AF ( audio frequency ) range ( HA HA HA ). If they do supply what seems to be a legit answer ( even bigger joke ) , ask them if you can get a copy of the electrical measurements that they've done on their cables. Since most "cable manufacturers" have never done anything like this nor have the phenomenally expensive test equipment to do this type of testing, this is a very easy way to narrow down who the REAL "wire / cable designers & engineers" are and who are "snake oil salesmen" that have simply jumped on a very profitable bandwagon.

Bare in mind that this does not mean that one can't come up with a "good" design working in ones' basement, but the chances that it is actually "superior" to what is already being manufactured are quite low. The main benefit to DIY'ing cables is the phenomenal amount of money that one might be able to save. The "fun" & "experimantation" factors are also quite high, making projects of this nature even more attractive. Sean

Kenl, cables of any type are a pretty subjective matter. As such, the results that one achieves ( or should i say perceives ??? ) are due to personal tastes and system synergy. Having said that, i think that Kimber 8TC's are pretty solid cables. This does not mean that i think that they are the "best" ( as if one could quantify such a thing ). Nor are they anywhere near the "worst". Personally, i would rank them as being one of the more desirable cables that i have run across. Obviously, others may agree or disagree.

The results that you get with them ( or any other cable for that matter ) in your system will depend on several different factors. Since speaker cables account for only a small portion of the complex impedance that your amplifier sees and tries to load into, the results of changing cables will vary from system to system and combo to combo. Some systems will show drastic differences from cable to cable whereas others might not even "flinch". The only way to find out if you really like the Kimber's in your system or if your amp / speaker interface is susceptible to sonic variations with speaker cable changes is to try a couple of different designs out and see. As you probably know, i always encourage people to find out for themselves what they think works best. The education and experience that one gains along the way can be a lot of fun and help save you money in the long run.

Having said all of that, try taking a look at the A-gon thread entitled "Cables 101" as it may pertain to your question also. Sean
