Long RCA ICs - which ones fit this bill?


I plan to hook up a Pass X1 to a FetValve 550. As van Alstine amps do not have XLR ins I have to use single ended ICs. The kicker is that they need to be about 25 feet long. I spoke to both Frank, and Kent over at Pass. I am advised to use a straight coaxial design, fully braided shield, with as low a capacitance per foot as possible (<< 20 pf/ft if possible). The other kicker is that I don't want to spend an ungodly sum on these cables. What can I get in the cheap category that will fit the bill (not to exceed $1000)?

Tony, check this thread concerning MITs. I found that the long MIT cables were about as good a value as possible in the <$1k range.
Tony, they were connecting an ARC SP-14 pre with a Bryston 10B active x-ovr which was driving (for low end) a Levinson 23.5 and (for high end) a pair of ARC triode monoblocks M300 MKIIs. I was using pairs of 1.5m Magnan Vi ICs between the x-ovr and the amps. I was also using two pair of Maestro speaker cable.

The Maestro is one of those products that have held up over a long time, both in performance and (more and more when purchased used) in value. Sort of like SME tonearms, or SOTA turntables -- dependable, reliable and predictable. Their sound (freq.response) is very neutral (flat), and they are very resistant to picking up noise and hum. Compared to the latest advances in cable design (Purist, Transparent, Siltech, and many others) they are a bit, oh, reserved -- meaning a little softer on the attack, slap, slam, and lack the abundance of shimmer some of the newer high priced stuff allows through. But you'd have to spend at least 3x more (used) to do better. Remember, this was Straightwire's top cable for about 5 years.

I still use mine to connect my Levinson pre to my ML Depth sub.

Jfox's recommendation of the MITs is a good one also. I don't know how they compare pricewise, used. My last experience with MITs as my primary ICs was with the original 330, which got replaced with Straightwire.
330 v. Maestro? Maestro has has a bit more of everything that made the 330 so popular, but most noticably in improved image/soundstage. I guess it does a bit better reducing time smear.
I have much direct experience with MIT 330 vs. Straightwire, in this case Straightwire Virtuoso. The Virtuoso is the line above the Maestro. Throughout the late 80s to mid 90s I had used exclusively MIT 330 with ARC SP-10 and Adcom and ARC amps. I then tried 2 pairs of Virtuoso ICs here with good results. Where the MIT was mellow with a more distant and rolled-off presentation, the Virtuso was lively, dynamic and extended on the top. I then switched to a 3' pair of Virtuoso speaker cables as well over the MIT 750s.

Years later as my system became more resolving, other components with greater coverage in the trebles, etc., it was very clear the Virtuoso was anything but neutral and natural. In fact, the more refined and extended my system became, the less I could tolerate the Virtuoso because of fatigue. In a word, it was BRIGHT.

I sold off the Virtuoso ICs and slowly moved to Cardas & SilverAudio and then later NBS and now Purist. However I kept the Virtuoso spkr cable which sounds today quite decent in my system. Compared to the Purist Opis I am currently auditioning, the Virtuoso still shows a little forward presentation on the top, but for the cost, it is very good.

Going back to MIT 330 ICs would be impossible because their resolution is simply downright poor in the context of a highly resolving system today. And going back to the Virtuoso ICs would be equally impossible because of the faitgue issue. I have no idea what to recommend in the $200-300 price range for 1-2m ICs, but if you need to go to the 25 feet zone, the MIT 350 Ref Proline CVT and 350 Evo cables I discussed in the other thread have no peers for performance and value.
