John Curl's Blowtorch preamplifier part II

[a.wayne]

Yes from bad tracking TT .... Now , with your listening room at 44db background noise, how bad is groove noise vs digital noise ...?

PS: Still waiting for Sy to answer ...

As you've been told half a dozen times, I did give you an answer. I cannot give you an understanding.

 

[a.wayne]

You never answered , so hence no understanding ....

 

[SY]

I also cannot teach you to read.

I am not saying "bad". But definitely audible, especially for pianissimo music. Smoothing Masking

Usually, I don't hear background noise in the electronics, but sometimes I hear the goove noise when playing a record. Guess what, Jack Bybee showed me a way to REMOVE VIRTUALLY ALL the groove noise with a simple quantum part in the input. I will try it at home, soon, but it really works! He did an A-B on his system where the electronics is comparable with mine.

C'mon Uncle Sy,

Free up some of that knowledge, noise floor at 44 db, 3M listening distance 89db/W/m speakers, digital noise advantage...?

I do agree with you on Piano, speed drift is an issue, on sprung turntables, it's mostly from the suspension, in need of new springs or adjustment ( motor aside) on really good TT's with good speed stability( read: heavy , big, ) it is not an issue.

Piano will eliminate the TT pretenders quickly ...

Already answered. Please learn to read.

Groove noise is dependent on LP pressings and TT tracking on better pressings/arm/cartridge setups noise is usually in the noise floor.
Huber's new FMA phono stage has a circuit to cure pops and clicks, it works without audible degradation...


PS: Thanks Uncle Sy ....

Resolution Series 223 PhonoMaster
Entire unit uses discrete circuitry of proprietary enhanced Class A design: no signal-degrading IC’s, transformers, hybrid circuits, tubes or op-amps.
That should make you happy JC!!
Has anyone evaluated this?

 

[jacco vermeulen]

If you can't drop by, there's a demo video of the 223.

There are plenty of the 8 legs hidden very highly acclaimed phono pre's. You place the SOTA qualifier on it so what am I to say, who determines that? I've had at least two of JC's highly respected buddies do it.

Would you participate in a real no peeking A/B?

I would.
Though no switching box, no switch between sources and I have enough time to listen, on my own audio setup.

 

[Joshua_G]

Not unless SY is there to referee. You could probably get your hands on a really well built version of Thorsten's Pacific pre with good PS and EMI precautions.

Thorsten's Pacific pre is a discreet one (JFETs).

Joshua,

Mr Wurcer likely meant it takes 2 to tango.

Advocate to Mr. Wurcer?
To me, Mr. Wurcer needs no advocates, he proved himself in action. I may not share Scot's views on audio and sound, however I have high regard for him as a human being.

Had the model before without pop/ click feature ....

Location: At the sea front, Rotterdam or Curaçao

Easy Dutchie , I can be next door .....

 

[mlloyd1]

that video demo of the 223 removing snaps, crackles and pops is pretty cool.
any ideas how they do it?

Groove noise is dependent on LP pressings and TT tracking on better pressings/arm/cartridge setups noise is usually in the noise floor.

If the groove noise is in the noise floor, it must be very poor phono preamplifier design.

Traditionally this is done with slew-rate dependent filtering. Crackles and pops generally have higher slew rates than the music and that triggers the filtering.
Such units come and go seemingly once every decade
