I have one
Nakamichi 600. It has that slooping front.
I used almost exclusively TDK SA tapes .. for Chrome Type setting (see text below).

My machine today is just gathering dust.
Eventhough I have many many cassett tapes with olden goldies music.

Quote:
In the seventies, your average cassette deck struggled to stretch up to 11kHz with Ferric tape,
and wow and flutter figures of 0.5% weren't unheard of
- but the 600 offered 20Hz-20kHz and 0.09% (peak DIN weighted)!

This was possible thanks to a superbly designed and made record/replay head and superbly aligned - albeit relatively simple - transport.
The final link in the chain was superb audio electronics
which were as crisp and clean as was possible to find in any tape machine.

The 600 is fully configurable for either Ferric (EX) or Chrome (SX) tape.
Metal tape for cassette use had not been invented and Nakamichi wasn't a fan of Sony's new-fangled FerriChrome formulation.
A built-in 400Hz test tone is provided,
which in conjunction with separate left and right pots for recording level, bias and IM suppression (Nakamichi's proprietary intermodulation distortion suppression system) for both EX and SX tape,
lets you tailor the machine to the tape with great accuracy.

No other rival design offered such adjustment, and the result was an incredibly convincing sound, even by today's standards.

Set up the 600 for TDK SA and you get a bright, powerful and lively sound
which doesn't just impress in the hi-fi sense but also in terms of musicality.
There's so much energy you wonder how cassette could ever sound so bad on other machines.
Bass is taut and powerful, with real slam and drive.
Midband is wide open, with stacks of detail and strong image.

Mine is a diffirent brand, but good quality nontheless... was actualy used for band recordings etc...

One of the reels I have is a recording of a stock car or motorbike... absolutely sounds like hell breaking loose...

My dad used to carry the speakers out at 3 in the morning and blast that track if the neighbours were too noisy...

Default I am very good to adjust (calibrate) tape recorders


sadly all my know how is collecting dust.

I have spend 7 years only adjusting those machines...bias, record level, playback level, rec eq. and playback eq.

They are not more used.... modern folks do not tollerate the tape hissing.

Nice machines..... sadly the are, now a days, alike a steam train.

history of modern audio

The pop era.

1. Turntables and LP, EP & Single vinyl records at 33/45 rpm
50 & 60-ies when elvis, bob dylan, beatles & rolling stones came around

2. Compact Cassette Recorder and tapes
70 & 80-ies when came more hardrock & disco era

3. Compact Digital Disc and CD player, with 16-bit 44 kHz sampling
from 80-ies and onwards & still today


This is audio history for many of us.
In a nutshell
