Trying different type and length Interconnects with Inspire
Question to all Inspire owners. I don't mean to get off track too much, but this question and finding seems to also change the sound to a notable degree within my system. I'm enjoying rediscovering different interconnects, sounds, because of the inspire. I'm messing with RCAs between the preamp and amp and and my sources all over again since realizing notable changes to sound with this newer inspire. Kinda fun.
In my system, I noticed the Inspire can be sensitive and benefited by different type and different length of RCA interconnects. Maybe it has to do with capacitance, I don't know. What do know and hear is difference to sound with changes. I wanted to try this with all of the stock KT150 tubes that came with my Inspire unit. Kinda cool how it can be further tuned with cables alone. Also noticed how it can degrade sound and become less engaging by going with generic low grade cables too. So far, I'm trying different type (silver, copper) and varying length interconnects from .75m to 1.5m so far with capacitance between 15 to 25 pF. While I've noticed changes on my other amplifiers, it seems to be even more evident (positively/negatively, for whatever added voodoo magic reason) on my Inspire Hot Rod KT150. I may try some 2m+ pure copper interconnects next between the preamp and amp. Or, you can tell me I'm full of it, makes no difference, that's okay too, feedback is feedback. :) Anyone else happen to encounter more noticeable changes with the Inspire? Did you find any benefit going with longer than 1.5m interconnects on yours? |
Purist rule of thumb: The shorter the interconnects' length, the less potential for these to work as an antenna for EMI. Besides, the shorter the signal path, the better preservation of the original source signal. And, yes, different metals sound different. In general, silver-prominent cables are brighter and more detailed than copper-prominent mixtures, which tend to be warmer and more forgiving, OTBE. Trial-and-error is suggested for each particular setup.

Question - re: preamp
Do any of you guys know of a simple (new or used) single source tube preamp that would be a good match for the little Inspire KT150 Hot Rod? -I can't keep swapping my Cary SLP-98 in/out from my other amp to the Inspire. -A clean and simple little tube preamp (with correct output voltage) would be great. Thanks ahead for your ideas and responses. |
Recommending a preamp is a difficult assignment. There's a lot more to it than just gain, as I'm sure you know. A lot of system synergy and personal preference is involved. Would you want it to sound a lot like your Cary SLP-98? That preamp has a reputation of sounding a little "tubey"/smooth with great vocals.
