I love normal tape-noise. It identifies the time we listened to analog music.

The Super D has some noticable noise breathing, but undoubtely better with it on :) The High-Com also has it, but it seems much more subtle (could be the lower compression ratio?) My favorite is actually the ADRES. Never heard about that one before. Fantastic comparison

Thanks WIlliam. Indeed, the lower compression ratio and different filtering and emphasis systems will most likely have resulted in the slightly better result with HighCOM II. Toshiba A.D.R.E.S. works great, and it's also one of my favourites for recording cassettes. AD-5 units are quite rare, but AD-4 (that were released later) are easier to find. I can highly recommend one.

I think I liked the Sanyo Super D. It's hard to tell though through pc desktop speakers..

The adres kills the high frequenties. Sounds stable but moufled.

Pretty instructive and very interesting.

What a discovery! Let's see)

Nice comparisons. But you do need to look into the wow and flutter of that deck, it is even audible with headphones on! The CD1 should be able to do a lot better!

Very interesting comparison, thank you! It would have been helpful to hear the original recordings, though, in order to know how noisy they were originally.

Thanks ! At the end of the video you can hear the recording without any noise reduction.

Very interesting!! I will have a close listen to this later.

I think dbx sounds very good, ADRES very close, HighCom good, Sanyo not so much.

I received a frequency response printout for my Technics RS-M233X (short head with an oval cutout, there is also a normal long head with a square cutout in the tread on this model, I had 2) from a guarantee workshop. Without NR +/- 2dB, with dbx +/- 4dB. - was below 1KHz, + was above 1KHz.

DBX in itself has no influence on the frequency spectrum (as in : it does not introduce a + or - difference, the encoder/decoder has a flat frequency response from 20hz to 20kHz)). However, if your deck has a frequency response without DBX of +/-2dB, than enabling DBX will double that to +/-4dB, because the encoder/decoder system of DBX works on a ratio of 2:1:2. in short : any shortcoming in your deck will be "doubled" by the DBX system.

Did anyone noticed different readings of VU between deck and high com? I mean, I have 4 decks and all of them showing different values of VU of the same recording. What kinda jungle is it?

Very good video! I have a Toshiba-Aurex PC-X88AD with adres, (that can be used as stand alone unit) and it is excellent.. Better than Dolby. Also I have also a Teac AN-180 Dolby) , I have to test it better, but it seems very very good

Thanks Roberto. I also own a Teac AN-180. I have recapped it and re-calibrated it about 6 months ago, and yes, they are very good, even if only Dolby B. Next to this, I have a JVC NR-50 in collection with Super A.N.R.S., Telcom C4, Telefunken HighCom, DBX150 Type I, etc... Fun stuff to experiment with. If you want to check out Telcom C4, check my latest video on Type I tape. I used a Telcom C4 unit in combination with a bottom of the range Type 1 tape, to investigate what level of quality you can obtain. this is the link : kzread.info/dash/bejne/i3t8xqexntatYZc.html

@@ralphlauwaert2245 wow! Telcom C4 should be the best! I will look to your video for sure, thanks!!!! I tested the an 180 just today for the first time, I found it some years ago but never used.. Did you recap it entirely? Thanks Congratulations for your wonderful devices! 🆒🔝

Maybe, combine them all for the very best results?

hi Ralph, I own a kx1200 Yamaha with dbx, is it dbx I or II ? can't find any info about it. I read that dbx I is only for professional audio ?

That deck has dbx ii. Indeed, dbx 1 is for professional applications such as high speed reel to reel machines.

I use Hans-Peter Roth test tapes.

Hm.. They all cheat, just removing everything above 9-15kHz (and compress everything below of course). I wonder are there any digital companders that use ADC/DSP/multiplying DAC as a VCA? I don't need a compatibility with other decks, I just need no unpleasant hiss. Traditional companders are too slow with their band pass/hp/lp filters. A signal is already gone at a moment the filters output some voltage for VCA

"removing everything above 9-15kHz " , are you sure about that?I've done measurements on virtually every noise reduction system there is for Reel-to-reel and cassette, and never observed this. If you want the best available system, use Dolby SR (it works on cassette too! just keep the recording levels conservative), Dolby S, or Nakamichi HighCom II, or , in my opinion the best one for cassette : Toshiba ADRES. I know Pioneer did some single-ended NR system on some of their decks. But for the best performance, get an outboard NR system. DBX II units are well available, and also do a really good job. Only on very high transients, they might be (just a very little) sluggish

It's simple, just use digital recording if you want 'no noise'. And you can get super high frequency response too! 😉
