One man's experiences ...

The best way to maximize signal-to-noise ratio on playback of old grooved disks is first of all find 
the best example of the disk in question, then clean it thoroughly. Then play it back with the right 
EQ curve on the preamp, starting with whatever is documented for that label/studio and era and then 
confirming or changing that based on your own careful listening through a good playback system.

With old 78-era disks, there is no magic machine. Some of them just sound like crap. Some were 
recorded just plain badly, under conditions that wouldn't yield a good recording. And some were 
pressed on junk material, or had noise added from primative or faulty plating and pressing, etc. 
There's no hard and fast rule. I have some acoustic-era disks that sound amazing given their age 
(frequency-constrained and somewhat noisy but the instruments sound like what they are and not tinny 
cartoons), and others that don't sound like music. And there are some electric-era disks that sound 
crappy, too, but it's less common as time goes on, especially for recordings made in the major 
studios (location recordings were catch as catch can, some excellent and some terrible). None of 
this is that much different from any other era, by the way, the majority of recordings are average 
to unappealing and the rare ones are what jump out of the speakers and involve you.

Joe Salerno is correct in that modern digital tools can do a better job of repairing pops and even 
some groove distortions (my experience is, the most effective tool is the pencil tool and lots of 
human time invested to correct things, but there are some automated processes that can be helpful if 
used with full human hearing engaged). The old analog "noise reduction" tools are worse versions of 
the same life-sucking EQ tricks that over-used computer tools sound like. Usually, it's best to just 
ignore the noise and enjoy the music. You can do some experimenting with low-pass and high-pass 
filtering, it can help. But with 78's, proper turnover and rolloff help more than anything else.

Subject: [ARSCLIST] Esoteric and Rekokut vintage sound restoration modules


Have anybody had any experience with the various sound restoration modules from KEK-O-Kut and 
Esoteric on playback of 78 rpm records?

I think about the surface noise reducer and the de-hisser units, also the RE-Equalizer...

Best regards
