Re: PV8 preamp high output

Hola Paco...ya le escribí a Efrain. Con un divisor PI, te lo puedo hacer. Necesito que me traigás el pre y el amp...con todo gusto te lo fabrico. Saludos, Roberto. Hello Paco... I just wrote to Efrain. Nothing is wrong with your preamp or your amp. The problem is that your PV-8 puts a lot of output ...

Re: Difference between a Evolution 20 and 20SE

Love to help!...by the way, I do know that the metal foil resistors improve the S/R about 5 to 10dB. This means less hiss or noise at the noise floor level. More micro-dynamics, better resolution and more musicality overall.

Happy listening!

Re: Difference between a Evolution 20 and 20SE

Hola Robert. SE stands for Special Edition. Just address your question with the owner-partner of C-J Mr. Jeff Fischel. His email address is jeff@conradjohnson.com. Ask your questions, he is a very humble man. He will answer your questions more precisely. I have being with C-J since 82 here in Costa ...

Re: new ET-7, the replacement for the ET-5

Follow up... My ET-7 is now fully broken-in, and I can say that it is singing like a very expensive canary. Where I am listening a big difference is at the human voice. Here it shines like a 24 Karat gold. Its smooth, having silky strings, and tons of definition. Truly sense of 3D, with outstanding ...

Re: New phono.

Jonty, I do know that RJ loves my speakers...all I can say is, the ET-7 brought to my system a new way of listening experience. My system has never gave to so much pleasure as it is right now. This is what C-J is. It just sounds right! Take your time, listen to old music, the one that it is in your ...

Re: Difference between a Evolution 20 and 20SE

Robert, I do believe that the metal foil resistors are new components in the SE versions. You should try to get them. Also the benefit with the Teflon Caps, is that they hold their capacitance in all the working voltages. No matter the change in voltage, the capacitance value is the same. On the oth...

Re: Difference between a Evolution 20 and 20SE

Agreed, C-J really sounds right! On the other hand, the teflon caps are really very good, and the metal foil resistors are very low noise, giving up to 10dB better of S/R. Musical instruments are more palpable, more real, with the right timbre and dynamics...I do believe that the SE version really w...

Re: Difference between a Evolution 20 and 20SE

I also had an Audio Research VT-100MKIII modified at the caps and resistors, keeping the same value of the components. Also, I used the KT-120s instead the 6550s. The bias adjusted for 130mA at the bias resistors. Honestly, I had it for over 8 years once I did the mod. Now I did change it for the ne...

Re: New phono.

Jonathan, The first thing that I did find, was the bass, deep, robust, with the right energy on every note. Then the stage. I did opens wide and with the right sense of 3D. Vocals are without any sore-throats, and the timbre of the wind instruments is metal! For the clarinet or oboe, you can hear th...

Re: New phono.

Jonty, that's what is going to happen to you. Re-discovering all your music or should I say the musician(s) playing for you there...in your own place. This is what I do like most. I am really a frustrated musician. When I was attending to College, being 18 years old or so, I had been receiving class...

Re: New phono.

That's the best way to do it...I recommend to you to listen some music during the process so, you can tell the marvelous change for good in the magical journey for stage, timbre, size of the instruments, and vocals. We have here another great Conrad Johnson user who says this process is not necessar...

Re: New phono.

Jonathan, what I did for bring down the break in time, was with Internet music (youtube) and left 24 hours continuous playing at a moderate level, where it did not disturb anybody at the house. The first 100 hours were crucial, the change for good was astonishing, and when I got the 400 hours (+-) e...
