Charles,
The JISCO, which by the way is a very nice name, is very, very facinating. I can't believe the level of performance its brought to my digital rig consisting of the Sony SCD (used soley as a transport), the Perpetual Technologies P1A/P3A combo, and the Tact 2.2 digital room corrector/preamplifier.
The difference was very apparent right out of the box (does this product require breakin?).

Everything become somehow smoother and richer in overtones. I thought that the entire sound became at once more natural which is what I've been after all my life, and the main reason why I chose the Talon Audio Loudspeakers. They're very natural sounding. So you can imagine how impressed I am by the improvements the JISCO brought to my listening environment.

Do you think I could use another unit if I'm using three digital components in the Sony transport going to the P1A to the P3A? Wouldn't be ideal if I had another unit right there at the P3A or does the JISCO do fine enough at the input of the P1A which is a sort of upsampling/resolution enhancement device that goes to the P3A, which is the DAC.
If you can spare it or tell me my price, I would love to have two more units (one more for myself) and the other for a host of reviewers here at Stereo Times like Mr. Jim Merod or perhaps Marshall Nack.
One thing is certain, the JISCO is doing something that most, if not very many, two piece digital front end users will love and appreciate.

Charles,
First let me wish you and your family and very prosperous new year and hope this year will be very successful for you. You have some product in the JISCO that's for sure!
I installed it almost immediately after receiving it last weekend. The differences it showed were very impressive right out of the box. Now if you are not aware I'm right now using the Sony SCD1 as a stand alone transport while my jitter and resolution enhancement device is the new Perpetual Tech. P1A. The dac that is also made by PT is the P3A. Well to make a long story short, your JISCO device gave a natural presentation to the rig that it never had before. It's natural sounding and had all this going for it before, but not to this degree. This is less harder on the top while making massed strings still sound clearer and better focused. I really am finding it tough to find all the improvement it does without writing a review right here. All I will ask is that you send me two more units if you can spare it. The reasons are: I need an additional one, unless you think otherwise, on my dacs input, since the one you sent goes on the P1A's input. I only wonder what it would do for the dac! The other would be for a couple of reviewers here at the magazine to publish articles that will prove the same results in their systems.
The one thing that makes us so successful to our many readers is that we publish reviews of components by more than one reviewer. This is very important so that our readers know we're listening in a variety of systems and setups. So the product under really works. Not just in one system.
All I can state right now, again without feeling as though I am giving away secrets is that your product works as stated! The amazing thing is I didn't think I needed its help. But sincerely do.
