Review 1 of 10

Price Paid:  $450.00

Summary:
I purchased this from a local dealer. I have a CJ sa250 songographe that I LOVE. Its as good as many of my tube amps, and one of the best purchases I have ever made. I figured the CJ pf2 preamp would be a perfect match for it.





Strengths:

The build quality both internal and external on this thing is spectacular. It uses an alps pot, resistors for the balance control which are out of the signal path when its centered. It uses all polypropylene and polystyrene caps, even in the power supply. The knobs are beautifully milled, and have a very refined purposeful feel. The case is solid and the front panel is thicker than my sa250.

Weaknesses:
This thing INVERTS PHASE. To get good sound you need to swap the speaker terminals. CJ notes this with a red insert in the manual. I tried it both ways, much much better sounding with the corrected speaker terminals.

I let it warm up overnight. The next morning the sound was not bad, but a noticeable step down from my homebuilt design. I was shocked. I played with interconnects, tried XLO speaker cables instead of my nordost, and cardas and xlo interconnects. No matter what the setup there was a slightly thin hard sounding lower midrange. I kept feeling like I needed to edge the volume up to enjoy the music.

At this point I was shocked. so I figured I would try my other backup preamp which is a very very old 1980s class A David Belles design. It doesn't even have gold plated RCAs. The David belles design was not as smooth as either other preamp but it did not have the harness.

If I had to characterize the CJ, it would be very hifi sounding. Smooth, with detail, and a controlled top end. I really really wanted to like this piece. It looks spectacular feels like a million dollars, and matches my amp. It was not a terrible sounding preamp but it did not do anything spectacular either.

Review 2 of 10

Price Paid:  $1550.00 from Superior Audio, IL

Summary:
I've had this preamp for 5 years. It's the PF2 (with phono). I'd have to say it's a very capable, very good sounding product. I purchase the rest of my system since purchasing it and the c-j MF2200 at the same time. I don't feel the PF2 has held me back until now. Given the cost of differential in the remaining equipment, that's quite an accomplishment. Kudos to c-j! I added audioquest big feet under the unit. That lowered the noise floor a bit, removing a layer of etch to the highs, tightened and added definition to the bass. A must tweak for this unit! In it's class, it has an open, natural sound. Very good resolution. Soundstage is deep and wide. Bass has very good definition. Individual bass guitar notes are readily distinguishable and have good body. Highs are clear and true. Triangles on various Classic symphonic re-issues are very realistic and pure. Female vocalist like Alison Krauss & Joni Mitchell sound like their in the room. It's dynamics are good, probably better than most in the price range at the time I bought it. In 1999, I compared it to c-j PV10 & PV12. I bought the PF2 over the PV12 which sounded too-rolled off on the high end. The PV10 just didn't have the resolution of the other two. The phono section is quite good although limited in gain. Loading resistors need to be soldered in-line in order to adjust moving coils. I used it this way for 3.5 years, before finally buying a Pass X-ono when I upgraded from a Ruby H to a Ruby2. The PF2 phono wouldn't have the gain to drive the lower Ruby2 and loading changes on the X-ono are dip switch controlled, much easier. The X-ono improved the depth and air around the instruments, really bringing them to life compared to the PF2. Although, I wouldn't go back, the PF2 phono was enjoyable and well worth the added cost. Provided years of fun. I'm now considering upgrading preamps. Comparing the PF2 to c-j's Premier LS17 (mk I), the LS17 is considerably better. And it should be cosidering price. The LS17 has a significantly lower noise floor. Which is easily noticeable in A/B comparisons, but having lived with the PF2 for a year since comparing, I don't miss it. I just know the sound will be that much better when I upgrade. The LS17 is clearer, has more texture and better image stability than the PF2. The unit is sensitive to static electricity. I have to ground myself after getting off the couch in dry weather to avoid nasty POPs. Particularly annoying since it has no remote. But the unit has never failed. Summing up, on the used market, this preamp offers great value compared to it's original cost or what it would currently cost to upgrade. A gem on the used market.

Strengths:
Image soundstage width and depth. Clear, natural sound. Very reliable, especially with no electrolytic caps.

Weaknesses:
Sensitive to static electricity. No remote control.

Review 5 of 10

Price Paid:  $570.00 from High Tech

Summary:
While on lunch break I walk into the shop to buy a CD and leave with something to upset the wife! When I asked to hear the PF2 I was expecting to look at my watch and concede that it sounds good and leave the store. Well, it did'nt happen that way! I can honestly say that the PF2 is among the best that I have ever heard! Of course the comparisons took place on the $7000 JMLab Utopia and a YBA amp, but let me tell you that the PF2 flat embarrassed the current production YBA preamp at $2200! To conclude, if you find one for a good price - grab it!

Strengths:
Huge soundstage, effortless delivery of complex musical passages, sounds REAL!

Weaknesses:
Havent found any yet!

Best Floorstanding Speakers Under $1000

So many to choose from! Lets us boil it down. How to Choose a Floorstanding Speaker that fits you:

AudioREVIEW's Budget Audiophile Holiday Guide

Give someone the gift of hi-fi. Or make the step yourself. Let us point the way...

Moscode 402Au OLT stereo power amplifier Review

George is adamant about the fact that the Moscode 402Au is not just a tube gain stage slapped onto a solid-state power amplifier; rather, it is a tube amplifier with a MOSFET output stage.

Lowther’s DX-65 driver in the Teresonic Magus XR Review

A new driver from Lowther is real news. A new five inch driver is even rarer news, so it was with great anticipation that I waited on this pair of speakers to arrive.

Aune Mini Headphone DAC User Review

The unit arrived from China well packed and everything seem to be in place. No external abuse by the carriers. The only problem was the power supply it came with. The box came with a cheap step-down converter.
