Re: ET250S or MF2550?
My ET250S worked well with any preamp--or no preamp at all, being driven by my Oppo 205--even driving 96dB-sensitive mag-planar hybrids.. It sounded superb driving my improved Audio Physic Avantis. I'm now considering buying another--two, actually--to drive my Vandersteen Seven Mk.IIs and later my ...

Re: M8080 Replacement LP260MSE Monoblocks
I had an MET1 years ago and researched--that means buying MANY and testing-as-best-I-could--MANY 6C4s..The biggest difference I found was in microfonics--very few had none or virtually none--and some hurt my ears as the preamp clicked on--I was sitting close to the speaker.. I suggest U buy a bunch ...

Re: Premier Five
CJ also has a Teflon-capacitor upgrade for the Premier 5; you might ask what that costs...but I'm sure it will be a bit breathtaking, as will the cost of 16 high-quality EL-34 output tubes.
Do let us know what you do.

Re: PV-12 vs PV-5 vs PV-8
Hi I am the happy owner of a PV-12 I am looking to get my hands on another preamp, and in searching for a PV-12, I also see the PV-5 and PV-8. Can someone either tell me what the diff is, or point me to a resource that will tell me? Thanks in advance. Probably you know of this, but just in case you...

Re: Premier 140 as monoblocks
First, as I understand it (and I certainly could be wrong), the two channels of a tubed poweramp CANNOT be 'bridged'.. Grossly oversimplified, 'bridging' is a way to convert two channels of a solidstate amp into a potentially LOTS-higher-power amp by, essentially, running the two channels in paralle...

Re: WANTED: CJ MET1 multichannel preamp
Not to gloat...but I had TWO while the first was back at c-j being repaired. Sold the extra quickly and the oroginal maybe two years ago.. It's an excellent-sounding MC preamp.
GOOD LUCK!

Re: NEW Conrad Johnson ART27A Triode Tube Amp
FWIW, these '88s in triode are run in push-pull and NOT parallel (ie single-ended), per 'Catherine' @ c-j.

Re: A question about tubes/valves
I also feel that different tube types are more rugged than others. The Mullard M8080/CV4058 was actually a military tube. This is electrically equivalent to the common 6C4. My PV14L arrived with a pair of Philips/ECG 6C4s, and I purchased some Tung Sol 6C4s shortly afterwards. Both of them experien...

Re: Breaking in the Teflon Caps upgrade.
500 hours! Dang, that's a long time. I'll think I'll park it in my office with something running into it and let her rip for a month or so. Assuming I have the patience. ... Tonye, just leave it turned on and playing music, driving the turned-off poweramps(s). That doesn't require any patience--the...

Re: Breaking in the Teflon Caps upgrade.
FIVE-hundred, not two-hundred, hours. As Admin writes, just play music into it. This process does NOT need the poweramp(s) to be turned on, as a preamp's load in the poweramp is passive--that is, just a resistor and sometimes a DC-blocking, high-pass capacitor. I hear more transparency overall with...
