John,Maybe a silly question, but did you ever seriously consider a cost-no-object exercise like that of the Blowtorch?
Rest assured that my JC-1s went to a good home. The guy is absolutely delighted to have Bob's personal amps.
So...when's that new Vendetta going to be out, hmmmmmm????? :-)

Didn't you realize they have a website? :-)
Best regards,
Thanks, Brian. Now there's something to look forward to!I hardly need to say that you should listen to the amps driving Sound Labs if the opportunity comes up, right?
Bob's JC1's? WOW! They are about as good as we can do with that design.
I really would like to try a zero global feedback amp at this point, but I doubt that I personally will ever make it. Parasound has been good to me, but I must design within their guidelines. This means reasonably low measured distortion and really high power.
Charles Hansen's super concern for power supply clean-up is also very interesting. I have not tried hard enough (so it would seem) to completely RFI proof my Parasound power amps. Of course, the CTC and Vendetta designs are pretty darn well RFI buffered, but it has been difficult to put that into high power designs. At this time, I am on another website, www.diyaudio.com trying to knock some sense into those 'designers' who laugh at Charles' efforts, because they don't use global feedback. He is apparently getting the last laugh.
Something tells me I know pretty well what forum you're talking about John, though I haven't been back there in close to two years. Some pretty thick heads there. Good luck!I have only heard the MX-9 in prototype form at last year's CES, but Chas was really jazzed about them then, and even how well they measured at that point due to some things in the VAS stage he hadn't tried before, thinking it wasn't the right thing to do- if we get wedded too much to our own dogma, it can be a hinderance at times. They did sound very good then, but he put a lot more work in and shipped the first ones over about three months later from what I heard than he originally plan- a definite perfectionist.
I've been so wrapped up in my day job that I hadn't even heard about the Thermal Trak parts from On Semi. Now I"ve got a few tubes of them to play with, but as usual no time. Maybe I should just start saving my spare change for a set of MX-9's... would be less work, I'm sure!

John,
Well, speaking personally, I sure would like to hear your best effort.Yes, these were Bob's amps. I purchased them from his estate last year. They've been wonderful. The MX-Rs are better in most respects, but not by that much. I have no idea if this is largely an RFI factor or not. Al Sekela, who posts on the Sound Lab Owners' board, asked this:
"Charles Hansen has posted on the Audio Asylum that his products do not use the AC safety-earth connection. This is a large benefit in many applications, since the AC safety-earth wiring carries RF noise from sources within the house as well as within the audio system."
Interesting stuff. For me, I'm just enjoying the music.
Or something of the sort not much availible in quality low power SS and with so many transducers on the market that dont need big power I feel you big amp guys are missing out on alot of sales. Times are changing somewhat big power isnt as popular or needed like it used to be.If you do market something sign me up to beta test;)
It seems most SS manufacturers reserve their best efforts for the highest power amps. I'd like to see some all out assaults on a 25-50W amp.
hey johni modded a couple JC1s around town, changing some of the parts that bob put in (the ACME is the wrong IEC for the amp; a gold-plated furutech is much sweeter, and a couple bybees never hurt!).
i've always thought that putting a TI shield (see percyaudio.com; its like mu metal) around the tranny would make a big / positive diff with the JC1---lord knows it does on every power conditioner that has a toroid in it. any thoughts?
Thanks Rhyno, any successful mods is appreciated I have 4 units in my living room at the moment and I am thinking of adding Bybees, etc.
