Advice for RCA Interconnect Upgrade?

Hey Guys,

Kinda new here and first time asking for advice.  Thinking about upgrading RCA interconnects between DAC and Int. amp..

Currently using CHORD Clearway 1M.  This is my system:

REGA  Aethos integrated amp. (no XLR )

Jay's Audio CD Transport

Denafrip's Pontus II DAC

SVS Ultra Towers (highly modified)

Silversmith Fidelium speaker cables

Using an app on my iphone, the response has peak db from 4k to 5k.  I would prefer to tame that a bit.

Of course I have power chord and AC line upgrades and such but I hope this is a good starting point for your help.

Thanks,  Lawrence From MI

@lrlacosse "This was done only on the upper and high frequency parts of the crossover. The inductors I wanted to use for the bass part are just too big and an external crossover would be needed. So, yes, probably my own fault for the bump in db in the 4 to 5k range. "

 

With the crossover mods and part changes, why do you believe you caused a bump in db in 4-5k range? Did you change the specs on parts used or change the crossover point or something?

I used a simple app on my iphone and a test cd. Probably not very accurate.

Gotcha. I’d be tempted to ask SVS to review/advise and send you an updated pair of crossovers vs. trying to mask the issue with interconnect cables. Don’t get me wrong, I’m a IC cable nut, tried way too many, yet fixing the root cause is usually the more beneficial option. BTW, I design(ed) and built speakers as a hobby 45 years. A proper crossover from a proven designer familiar with SVS drivers can be a game changer. Danny at GR Research could help if you wanna pay the price.  Best of luck.

Hey All,

Ordered and been using Triode Wire Labs RCA interconnect for some days now.

I'm impressed!  Noticed a difference immediately.  (was using CHORD Clearway)   First time that changing just an interconnect made such a difference.  The only other time is when I purchase Fidelium speaker cables/ribbons.  However, the change did not calm down that frequency bump in the 4-5k range.  I highly recommend TWL.  Never heard of that company before posting here.  So, thanks to All for the advice.  Looks like I got some crossover tweaking to do this Winter.

Hey decooney    -   SVS send updated crossovers?  SVS would never do something like that.  They would laugh at me if I tried.
