You're a funny guy.
As you state you build (DIY) the holy grail of cassette decks
Would you call, say, Nelson Pass a DIY builder of amplifiers?
Cheers

No but I can lead you to a place with at least ten people, each and everyone believing they are Napoleon Bonaparte.
Unfortunately, not possible. I did quite a lot of work on R2Rs - since about 1980s. Problem is not in the electronics or parts, it is in the physics. R2R tape magnetic layer is too thick for 7.5 IPS so the tape overloads pretty quickly at HF. Actually a good Metal tape at least equals a R2R at 7.5 IPS in this respect even at 1.875 IPS (4.76 cm/s). A dynamic biasing (i.e. "HX-Pro") may help to a degree. For quality R2R tapes 15 IPS is actually the optimum speed, for a cassette 3.75 IPS is the optimum, at 1.875 IPS it struggles.

1) You don't have to listen to all these thousands, only to some which considered among the best and I did.
2) Pure physics - no R2R at 7.5 IPS can record 27kHz at 0dB level.
3) I don't do DIY. I design, make and sell professional quality electronics.

I'd love to find a fully-working Sony TC-V7. I used to have one that needed the belts changed, but I couldn't figure out how to change them.
Another TRUE HOLY GRAIL... but Japan-only... :worried: Although a few units were found in Canada...

The JVC TD-V661 is dual capstan, slaved DD as pointed out, with very good specs, though I have never heard or owned one. Vintagecassette.com has it speced wrong, but the pic is correct. I should not have inferred that it was single capstan, belt drive based on one check point, my error.
That Tascam 122 MKIII is a fine looking deck, for sure. So many decks to try, so little time...
WOW! :drool:
That is just sex man.
I love ma ES gear....
Those Japs kept the best stuff for themselves![]()
One thing I want to ask/share with you folks about all these super decks.
If (yes, "IF") Philips, instead of engineering the compact cassette at a 1⅞ inch per sec (4.76 cm/s) speed with 0.150 inch (3.81mm) wide tape, had developed something just like 5 cm/s tape speed in a 4mm wide tape, inside a still compact cassette cartrigde size surely we would have recording machines that could sky-rocket easily the frequency response beyond the 20kHz and a S/N ratio close to 90 dB with type I (normal) cassettes without the need of any bloody Dolby NR...
