Well, This is the first time that I have read any postings in this newsgroup.
Let me give you a rundown on what I have and tell you a little bit about my
reciever....

I have

	Yamaha DSP -A1000 Amplifier
	Yamaha CDV 1700 Laser disk Player
	Mitsubishi U62 SVHS Vcr
	Mitsubishi 27" Dimond Scan Monitor
	Adcom Power Conditioner
	B&W DM-630 Monitor Speakers (For the front)
	B&W DM-530 Speakers for all surround Channels
	Velodyne Servo 1200 SubWoofer (BASS!)

I have owened a few kenwoods, and a cheaper Yamaha but now I think I have found
the system that I will stick with for a long time.....

Yamaha DSP A1000

This system has been rated the best Surround Processor by several magazines.  I
have done much research and have found nothing negative at all about this
reciever.  Yamaha made the mistake of making some real crap for a few years but
in 1991 they introduced a completely new line of amplifiers.  One of wich is
the DSP A1000.

This system has 80 watts a channel for the mains, 80 watts a channel for the
centers (TWO OF THEM) and 35 watts a channel for the front and rear surround.
In all the magazines that I have read, the system has been rated at more like 
120-130 watts a channel for the mains and 60 for the surrounds... But that is
irrelevant.  I have compared this system to their RSX-850 which has the same
power ratings and it is MUCH more powerful and dynamic.

What is different about the DSP-A1000.....

Well, First it has Digital Soundfielf Processing.  What does that mean????
Well, Yamaha invented a way to go into a room and record the actuall acoustics
in this room.  They first came out with the DSP-1 and then some other models. 
The A1000 is their latest.  Many people think that it is just a series of
delays but what yamaha does is sample the accoustics in places like Anahiem
Stadium, and the Village Gate Club (24 in all) and put them all on a chip.

Does this do anything???
YES.....
	What you hear, say in a club, are sounds coming directly at you, sounds
bouncing off the rear walls, and sound bouncing off of the walls behing the
perfomer....  With the DSP you get those accoustics usint the mains and the
four surround speakers...  One listen to it and it will blow you a way.

Also, Yamaha was involved in a law suit with Dolby Systems because they were
using DSP along with Dolby ProLogic (at that time with 30db Channel
separation).  So , as they say, "If you cant beat them join them", they did
just that.  They got together with Dolby and developed Digital Dolby Prologic
with 52db channel separation (every 3db is a double in performancd) and
combined it with DSP.  Well, what does this do??? It alowes you to emulate a
35mm surround sound and a 70mm THX surround sound...... This is incredible...
It is unlike anything you have ever heard....

The Yamaha also has stereo information in the rear channel, something that NO
ONE ELSE does at all.  And it sends the FULL FREQUENCY RANGE to the rear....
20 hz to 20,000 hz.  Most recievers send only 300-15,000 if that....  You loose
a lot without that info.....


Also with the two center channels, at the same power as the mains you get much
more oomph from the system.   It also has a variable subwoofer out for that
much needed BASS in the front.

Inputs

		VCR1
		VCR2
		LaserDisc
		Aux
			All with Video ins and outs (except the last two)
			And SVHS ins and outs.
		Tape1
		Tape2
		Dat
		Phono
		Reciever (the only thing it is missing)
		Monitor out (for superimposed video)
	
I think that is all of them...... 


One other point
	You can record from any source to anyother source and watch or listen
to any other source... REAL NICE.

It has pre ins and outs for all channels for upgrades in power and you can run
your rears through your mains if you get an amp to take up the mains slack.

And dont fear, if you dont want to get eight speakers, you can mix the front
surrounds into the mains with a switch and the centers into the mains via the
remote control.  All the DSP funcions are fully programmable right down to how
big the room sounds and how the highs bounce around, to how far you are from
the stage.... It is AWESOME!!!

Well, That is the Yamaha DSP-A1000 in a few words or less... I hope that I have
convinced at least a few of you to check it out.  As for the other things that
I have... Mitsubishi blows away the specs on anything else on the market,
especially VCRs... With rewinding a 120 min tape in 90 secs Flying erase heeads
and so on.. The Laserdisc player has the best specs on the market, at least
when I bouth it.... And B&W speakers are incredible... they are great for
movies and have the Finese to listen to Clasicall.......  And as far as
Subwoofers go... Velodyne takes the cake.... If there are any questions, please
feel free to Email me.. I will answer right away... And no!  I dont sell this
stuff, I am just someone who likes toys!!!!!!
