Have been enjoying my DSP A1 for about 4 months now and have not one negative thing to say about it, save for the cumbersome remote. I love the various DSP modes, although I use only a handful of them.
Any of you folks know a good source of info abot fine tuning and setting up the surround settings? I think I did it right, but I just can't help but think that I could have missed something that would boost the sound quality up to another level. BTW, I'm using the DSP A1 in a HT set up with a Panaonic A310 DVD and five NHT Super Ones & and NHT subwoofer.

Again, this is a solid unit and well worth the price. I'm even happier that I got the "international" model with the extra wattage!

I recently replaced my DSP A1 with the Denon 5700. I think the 5700 has a more detailed sound for both CDs and HT. The 7-channel doesn't make that much of a difference. I tested the 5700 in my home, on my system. It offered a wider sound stage compared to the Yamaha. And this was without any tone controls being adjusted. Most of the reviews here seem to be very money driven. As a caveat, let me say that how everyone likes sound is different. You cannot go wrong with either piece, but as far as future ready is concerned, Denon wins hands down. Also, better DACs and the best amps for an integrated component on the market.

I bought the DSP A-1 after months of comparing the systems. The denonin my opinion is not as clear sounding and as good an overall product as
the yamaha. I think the yamaha is the best sound processor on the market.
I am also suprised that someone would give the yamaha 2 or 3 stars when
most on the people giving the rating can only find a small if any difference
in the yamaha and their favorite system.

I think the yamaha is the best deal for the money. You get equal power to all channels where in the 5700 the rears are only rated and 1k instead of 20-20 which leave them a little over rated and not a good match to the fronts. Plus the soudstage is much deeper and more detailed then the denon. The yamaha is a better deal at the new low price and if you have the money to get a 5700 go to seprates. Like the sony 9000 combo.

My wife and I spent hours listening to other HT systems including the B&K 202 and the Denon 5700. I was all set to buy the B&K until I the last stop I made to hear the A1. It was so much better than the others that it made my wife and me giggle. It is a great sounding amp, full bodied and plenty of power. I don't understand the reviewers who have called it too bright. It sounds great on movies and excellent for music. I would have been happy with any of the three products, as they all have very good sound ... but the Yamaha was the only one that gave me goose bumps and made me giggle.
I have had it for about a month now and am completly satisfied.

In reference to the last review i would hope that the denon 5700 would have alittle gusto than the yamaha considering it took a year to get there line together.Now don't get me wrong i think denon makes a decent product i just like yamaha better.It's a matter of processing over just power.I have had the DSP-A1 since it came out and i don't think it's to bright mine is mated with polks and to me the DSP-A1 sounds sweet.I.M.H.O. i think it's a matter of taste but when you start pitting two brands that both have good and bad(WHICH I DON'T HEAR ALOT IN THE DSP-A1 OR THE DENON 5700)We miss the point. In the 70mm modes sci-fi or adventure,digital enhanced 35mm the DSP-A1 is great.As far as music the jazz clubs could put you sonic heaven.Great Product!!!!!

Powerful!!! This amp is so strong I have it only about 1/3rd of the way up. Clean and plenty of inputs. I got it at www.sounddistributors.com check them out.

I remember the first time I heard the Yamaha DSPA1 I fell in love with the ease of use and the quality of sound from a multi-function receiver. I normally do not like receivers but this one blew me away. We've had this receiver in the store where I work now for a number of months and has performed without any problems. The 96/24 converter is analog. I can strongly recommend this receiver to anyone who is looking for a top end receiver and confidently compare to others whose price may be double what Yamaha is asking for the DSPA1. My ranking for this reeceiver is definitely a 5 star ++++

Understanding the laws of physics would allow you to appreciate what you have discovered. When you decreased the room size, you effectively added constructive interference between you front and rear speakers or the bass signal between the front and rear channels routed to your subwoofer. This is normal and not a defect in any way. It is sad to see so many people who are misinformed or do not understand the operation of this fine unit. I would be happy to discuss this further with you if you want to email me.Another rumor that people like to spread about this unit is it does not have an analog bypass. That is not true. When the effects modes are off, the unit as well as all Yamaha receivers, operates in analog bypass.
