JC3+ Anyone?

"Have you checked out the Liberty B2B-1"

It was on my list. Only one XLR rules it out as I am not going to buy two. I do like your use of FETs. Been a fan of FETs for years. Had a Sony TA-1130 with MOSFET output devices.

I also like the way the JC3+ has premium parts in the right places.

" He solved the problems by building a fixed attenuator and inserting it between the JC3 and the preamp "

I read that thread, one of the best forum threads ever.

"half-output Kleos SL version at a later date"

Always good to hear from my favorite cartridge designer. If I send my Kleos back to Japan can it be converted? It needs a complete checkup anyway. Just started seeing the SL version mentioned. Have you folks not done an official announcement?

"Compatibility between phono cartridge output and phono stage gain depends very much on the gain of each component after that. The line preamp, power amp, and speakers (sensitivity)."

I am testing the XLR inputs on the CDP-500. One of the many nice things about the GCPH is the switches on the back for gain and loading. It will do 66db and also has a rotary control for the output section on the front. Overload would be harshness on the loudest notes, right? I am not hearing that but I am hearing what sounds like tape compression. I played my original Telarc 1812 and the KLEOS managed to stay in the grove on the canons but the loudest orchestra sections sounded compressed. This was with the GCPH on 66 and the rotary all the way. So that's like better than 11, yeah? :-)

BTW, as some might expect, the best tracking of the canons on that LP was via a Shure V15. I have a VxMR and I believe I had a V15III when I bought the 1812.

Thanks Folks,

"Robert,

The reason for only one XLR input is that the B2B-1 becomes a fully balanced amplifier when using the XLR inputs, and setting internal jumpers accordingly.

Running it in this mode will of course require two for a stereo setup, however in my totally biased opinion :-) well worth the effort."

Yep, I get that:-)

Hey Again Folks,

This testing is interesting. I may bore you with some of it later.

In the mean time, I am not convinced I have the azimuth of the Kleos correct yet. As I recall, there is a method of setting the azimuth using a voltmeter. Anybody know of a good article on how to do this?

Thanks,

Yes,

The JC3+ and I really like it.  It is perhaps a bit more forward than the GCPH but it adds detail without removing fullness.  It does NOT sound thin. 

The added adjustablility of the + is welcome as I have multiple tables and cartridges.

Take it EZ,

Hey Folks,

Anybody heard or seen anything about an update to the JC3+ ?  It's time for adjustable gain and maybe some other updates.

Thanks,

Robert
