Rgd Thanks for taking the time to answer thoroughly. Some nice equipment there, plenty of sensitivity for a good evaluation!
Sherod and La45, have you had a chance to install RX8man's isolation kit and what do you think? My unit is with Joseph at the moment and we are contemplating having him float the board.
Sherod - any further interm update on the V caps progress? Once the bypass caps have broken in, will you be A-B comparing them to the V caps alone?
Thanks Joe
Hi Joe,
Yes, I have installed the floater kit on only the tube board. Since I put the kit in at the same time that I added the V-cap teflon bypasses, I can't do a fair determination of how the floater kit has improved the sound, but I am going to take an educated guess that it's making an improvement as isolating the tubes and caps from the environment should help the sound improve. At this juncture, I have approx. 175 hours on the bypass caps. Still too early to make an evaluation. I am hoping to hear an improvement by late tomorrow evening when they reach the 200 hour mark. At this point, I'm not too impressed yet with the bypasses. I am missing the sweetness and transparency that the OIMP caps were providing by themselves. Up until about the 120 hour mark, the sound has been dreadful to say the least. These teflons are ugly sounding the first 100+ hours. By the way, Joseph and Victor are tonight, as I am writing this, doing an evaluation of the OIMP caps in Joseph's preamp at his home. Victor is going to give me an early opinion either later tonight or tomorrow. Their OIMP's only have about 80 hours on them, still not fully broken in( takes @ 200 hours) but 80 hours should give them enough to form an early perception of their potential. I hope to give a preliminary impression of the overall sound by the end of the weekend. By the way, what's Joseph doing to your preamp? You must be missing it in your system.
Yes, I am missing my unit. I have had a month of patience practice. My Northstar DAC was in for repair of two transitors resulting in no right channel. While the DAC was in I had it modded by Mauimods and just got it back yesterday with great results. Took it world class IMO.

Joseph is doing a permanent fix on the grounding issues I had when I got a custom AH (only XLR on the output side at my request). Meanwhile I am using my ss Aragon preamp. This hiatus has given me a chance to go backwards and see how much difference having a great versus good source and preamp has made. Boy, the difference is not subtle.


Hi Gammajo,

I have not installed the floating kit yet. I hope to do so next week as time allows and you will be the first to know my thoughts on what it does to the sound.
