Speaker Cable Lengths - W/ Monos


I'm considering having the manufacturer of my 10 foot cables cut the cables in half and re-terminate them for use with my Monoblocks in a Bi-wire configuration. They are very expensive cables, however, and I'd hate to cut myself short on cable (while also ruining their resale). At the same time, I'd hate to double up the longer length due to costs if I can help it.

My short term listening room will work easily with 4 1/2 to 5 foot cables, however, I'm not sure about a future room I'm planning.

What are typical cable lengths for those of you running monos out there? Is five feet usually enough? How far away from my speakers should my 150 lb. monos be?

Thanks in advance for any assistance.

Thanks for the responses. Sounds like chopping the cables into two sets is ultimately the way to go, although, perhaps not right now.

The cables are Tara "The Ones"
Audioman; I'm facing the same decision, and I've decided to keep my long speaker cables, then buy an 8 ft. pair of the same brand cables-- used, eg from Audiogon, and have them cut and terminated to less than 3 ft. for use in bi-amping. Good Luck. Craig
I,d ask TARA what there cut and termination charge is first.Some cable co. charge huge sums for this.

My mono blocks sit right under my stand-mounted speakers. Because the stands are quite tall, the amps are nowhere near the first reflection point. You cna also put them behind or to the side. Depends on the speakers. You of course do not want to block a reflex port or a low hanging woofer!
WAF issues resulted in my hanging my monos under the speakers' floor joists, then running 8' cables through the floor at the baseboards. Nice result: hidden (and cooler-running!) Class A monos, and only 8' cables. (Long UNinsulated Red Dawn XLR'd ICs are DEAD quiet, too). I had thought about sitting the Alephs right up against the speakers, but was told twice that 1.5m was the magical minimum cable length (!)...and then my spouse weighed in....so I decided to hide 'em. Good Luck!
