Sorry about the repeat! This is a correction from the last time. I
made a mistake on the S/N ratio.

I picked up a Harmon-Kardon hk400m last week. It is last year's
top-of-the-line HK deck so I got a good deal on it. For anyone who
wants a great deck but doesn't want to drop the bucks on a
Nakamichi, I highly recommend it. Here's a few point about the machine:

1) The two motor transport works very smooth and rewind/fast-forward
are VERY fast.

2) Has seperate EQ and BIAS settings for LN, FeCr, Cr and Metal
tapes and a bias trim control with a bias calibration tone.

3) Comes with Dolby B(tm) and Dolby HX(tm).

4) Can be used with the Nakamichi remote control.

5) Electronic auto search.

6) Auto replay or rewind. NOT REVERSIBLE, but this is only slightly
inconvenient.

7) MPX filter.

8) LED metering & headroom indicators. Selectable slow or fast
response.

9) Three head machine.

10) Frequency response rated at 15 Hz. to 23 Khz.

11) The record level is adjustible and a Dolby(tm) calibration tone is
supplied. The level adjustment is a little clumsy because a small
screwdriver is required and is slightly difficult. This becomes a
trivial problem if you mostly use one type of tape for recording.

12) Signal-to-noise 64 1/2db.(metal tape w/Dolby(tm)).

I just recorded a couple of Return to Forever albums on my first
metal tape and WOW. I used the combination of Dolby B and HX and, of
course, calibrated the deck for that tape. The signal-to-noise and
frequency response were excellent. I suspect that I will only use
metal tape on albums with a relatively high dynamic range and live
recording. I have used Maxell UD-XL II(tm) and there is only a
slight noticable difference from the metal tape. The main difference
was a few db. of extra headroom. The signal-to-noise improvement of
metal tape is only around 3-4 db. over the Maxell.

The 400 and this year's 401 are the only decks I would even attempt
to compare with the Nakamichis.
