   Well consider or not. Take a look at Receiver JVC RX-1050 (rather
expensive though but could be interesting when comparing features):

A = Analog I/O, D = Digital I/O, O = Optical interface, C = Coaxial
interface,   x = has,   - = has NOT

        Input                         Output
Source	Audio (D) Audio (A) Video     Audio (A) Video    Audio (D)

VCR1    -         x         x         x          x       -
VCR2    -         x         x         x          x       -
VDP     O         x         x         -          -       -
TV      -         -         -         -          x       -

CD      O         x         -         -          -       -
DAT     C         x         -         x          -       C (only if
                                                         input is Digital)
TAPE1   -         x         -         x          -       -
TAPE2   -         x         -         x          -       -

TAPE2 has ordinary "tape monitor function". TAPE1 has "tape monitor"
but can not monitor source from TAPE2.

When selecting a source (excluding tape2) the corresponding output
will be mute (to avoid looping sound). Example when selecting VCR2 all
other output excluding VCR2 will be provided with signal.

Digital output (to DAT) will only have signal if you have a digital
input => No internal A/D that provide signal to digital output exists.

Internal D/A exists (JVC PEM VANS D/A)

( VANS = Victor Audio Noise Shaper ( I guess))
( PEM  = Puls Edge Modulator)

All video I/O has ordinary composite signal (PAL or NTSC depending on
country) connection (RCA) or S-VHS interface but there exists no
conversion between the two formats. It is suitable when connecting two
VCR and one LD (VDP input).

It has 5 Power amplifiers, Dolby Prologic with digital processing and
a Digital Acoustic Processor (DAP) with 6 (SYMPONY, PAVILLION,
STADIUM, CLUB, CHURCH and OPERA) different sound pattern where you can
modify DAP level, room size, liveness and wall type.

SEA (Sound Effect Amplifier) EQ with 7 bands. 5 preset curve forms
(HEAVY, CLEAR, SOFT, MOVIE and VOCAL) and 5 memory to store your own
curve.

It has a sleep timer and switchable power outlet + 40 memories for FM
or AM radio. Each input is provided with 3 memories of you presetting
(like Volume, Prologic parameters, SEA, DAP, Loudness and so on)

Also provided is a huge programmable remote control where you can
store your remote codes from TV, TAPE1, TAPE2, VCR1, VCR2, VDP, CD (or
CD charger), DAT and an EXTra (like cable decoders)

Drawbacks:

1.) The lowest level of the volume level is too high. To listen to
soft music when goto sleep is difficult. The level should be down 10
to 20 dB more.

2.) The remote control is hard to operate in darkness even though it
has built in light.

3.) The SEA EQ operates only on the main Left and Right Channel.

4.) It becomes rather hot. => Not recommended to have anything on its
top.

    Value for the money?   I don't know. It's your choise.
