Warm, rich sounding interconnects?


My system is in flux at the moment with a Wadia Intuition 01 as preamp/amp/DAC bookshelf Tyler speakers and (horror of horrors) an iPhone with an Auris bluetooth connection for the current audio source. Since bluetooth at best sounds somewhat thin and tilted up on higher frequencies, it doesn’t play necessarily well with the Wadia which is great sounding overall but also can be on the revealing side.

I know I should get a better source - but even so I’ll always want the option of wireless in various situations. I’ve owned Purist Audio Museaus’s (rev-c’s) in the past, which would be perfect, but sadly sold them on A-gon some time ago. Those are hard to find and the newer Purist cables are brighter sounding.

So in a nutshell I’m looking for interconnects which will deepen and darken the sound for my current setup - and new/used for under $400. Any ideas?

And you should be able to get 2 sets of RCAs and one magic power cable I mentioned above for under $400 total. 
I agree with Ane re: Wireworld mid-level cales. On the other hand, they had really good imaging. :)


Belden 8402 w/ Switchcraft RCAs have a cult following in Japan and sound like what you are after. 
I have never heard of broken-in Purist cables being unfocused, but there are Purist fakes. As for bright, some mostly silver Purist with Ferox not fluid could be a little bright in some systems, my old Colossus RCA with Ferox is an example. It was fine before with fluid, but when the time came to fill it up, Jim of Purist only offered to fill it with Ferox, which, I believe, threw the cable off the balance. Not familiar with Museaus, though.
You could try Nirvana cables, they are out of business, I think, and hard to find.
I purchased the Purists new from The Cable Company which I know buys directly from Purist Audio.  These were copper not silver and yes I was surprised - but also knew the industry as a whole were moving to more revealing cables.  

Beldon 8402 with Switchcraft?  I'll check it out although I know the Asian market tends to be about the upper frequencies..
