"Faster" would probably mean that it has good transient response and lacks overhang, good things for most of us. Definitely sounds like a great design. Just waiting to see them manage the price down. But I am curious for sure. So the VPI 3D stays on what looks like a VPI classic?
My setup can't quite do what you described with that wood flute recording. Still some things to do on the preamp and the mid/tweeter amp is going to be substituted with an 805 SET with the feedback loop removed, when it becomes possible.Also looking for the option of a non feedback parallel KT150 or KT120 SET - someone is making them in China and I am looking for Western reviews.
I get what you say about the critical role of a well executed preamp. My modster friend finally finished his non feedback preamp and it took replacing the Van Alstine Dyna PAS' power trannies with new Edcors ($500) taking up 4 times the space, and added choke and separate filament power supplies. He transitioned it to the basic Herran circuit with no feedback and a single gain stage - down from 3 he started with.Desite this, his power supply box can't contain all the giant film caps and the preamp section is full of foil caps so he had to hang the trannie and choke outside the chassis of both the PS and main box.

Right about the VPI Classic Signature with a 10.5 3D arm. This is a Fantastic table btw and to do any better I felt I really had to make a pretty big leap to the TechDas 3 price range. The VPI table stays in the current system with the JL7's and Quads. I'll probably end up with the GAT2 back in that system and put the Legend with the Giyas. At least I'll try that combination before anything else.
So its Quads, CAT JL7's, GAT2, Premier 15, VPI/3D arm, Koetsu Blue Lace in the Planar system and Giyas, CAT Statements, CAT Legend, TechDas 3, Graham Phantom Elite arm, TechDas cartridge (Air tight mod) in the dynamic system. I should have the dynamic system up and running in about 2 months. I have some more construction work to do with the new dedicated room all of this will be going in. Then I'll spend months dialing everything in all over again for the new system! In the mean time the Quad system just keeps getting better as it settles in. This will be one heck of a shoot out and could be sort of a revelatory experience about top of the line planars vs dynamics. Can't wait to get it all set up.
On another note...... With the Quad system, I have all my cables (power cords and interconnects) elevated on Shunyata cable lifts, except I didn't have enough lifts for the power cords to the Quads or the power cords to the JL7 amps. Well, I found some more older generation Shunyata lifts sitting in a closet and put them in the system and wow what an immediate difference that made.
An entire layer of glaze that I did not know was there just disappeared! This turned out to be a serious tweak in my system for whatever reason because I thought the system had already reached maximum transparency. With that glaze removed, a lot more detail is coming through, and it just draws you into the music even more. I'm hearing things on recordings that I had no idea were even there. The piano peddles, chairs moving, lip smacking, breathing, etc that I had not heard before. I did hear some of that before, but I'd say its more than doubled. And all of that means more music as the detail just draws you in. Totally compelling and who would have known if I didn't try those lifts.
Interesting work by your modster friend Satie! Sounds like some serious internal surgery on that preamp. Way past my entry level knowledge of this sport. Good luck with your preamp mods too and hope all that works out. Also, I'm still processing your post sent PM and will be back on that later this weekend. Take care.
From what little I understand of it, the lifts are supposed to do two things - restrict vibrations coming from the floor and remove the asymmetry of the dielectric field (air above, floor below) so that lifting the cables reduces dielectric losses and lets the cable designer's deliberate balancing of cable properties to work in reality. Most of us don't have the electronics and speakers that would reveal the effects. In my case the bass cables are long but the mid/tweeter cables are just short of 3 ft. and touch the floor for a short distance. Besides which, my room is too crowded for cables not to be a tripping hazard as the speakers are in the middle of the room. Put them on lifts and it is assured to be a disaster..
Maybe its a cumulative thing as well. I already had my speaker cables and power cords to my subs up on lifts with good results. But when I also lifted the power cords to the Quads and power cords to my CAT amps, there was a whole new level of improvement and it wasn't subtle or hard to hear. It was plain as day; as if a nasty layer of glaze had been wiped clean.
The only cables left to lift in the entire system are the 2m interconnects from my preamp to the amps and thats going to be a little tricky. These interconnects run through a space that's under my 450 lb equipment rack so I've got to get behind that beast and find a clear route around the sides where I can set them up on lifts. I've studied it and there's a way. Now I just have to find the inspiration to do it!
Maybe next weekend..... But I've got to hear what if any difference it makes to have every single power cord and interconnect off the floor. If this last change adds anything like the power cords to the Quads and amps, I just can't imagine how good it will sound. :^)
