I love the DSP series from yamaha, ya know the kind, the ones without the tuner, and overbuilt, heavy as hell? I have talked to a few members in my 4-5 years on AK, and never thought to share pics... these are highly underrated monsters IMO. Here is the list of the dsp's that I've had.

dsp-a1000 - shoulda kept it :tears: pawn shop in utah $40 is all I got
dsp-a2070 - more processing, not as good of condish... weird channel cut out
dsp-a3090 - Obviously a nice upgrade and 5x80wpc instead of 80x3 25x2
same basic sound, ya know, the yamaha one. Never seen a speaker that these machines won't run. never tried maggies though. so, show em off if ya got em.... maybe help these machines get more recognition. they spec really well, and it's a hell of an 80wpc they claim. way underrated components. on the bay they go so cheap it's a damn disgrace. cheers!:smoke:

Started with the DSP A1000 integrated when they first came out and separate Yamaha high-end tuner and I think I eventually sold the integrated for $700.

Eventually I moved on to the DSP-A1 integrated (retained the tuner) and still have both sitting in boxes in perfect mint condition.

When we went with a LCOS projector we needed a means to switch component video, so an RX-Z9 was purchased. This one includes the tuner and the tuner is not nearly as good as the separate offering of the past.

I bought a DSP E1000 in 1993. I think it was the biggest waste of money I ever made. I removed it after a few weeks of trying it. It's still lying in my store room. It was the first & only piece of Yamaha stuff I've owned, but it made me not want to buy anything else of theirs. A definite thumbs down.
 
please don't let that experience spoil yamaha hifi for you, they made and still make some very clean, heavy built and powerful receivers? the dsp-a series is diff than that of the e series you speak of. these are just home theater type receivers, but are more modeled after hifi separates inside. They do waste some space inside with chips/dsp logic stuff, but the amp section is all balls, if you know what I mean. I found that bridging the 3090 I have it has developed a lot more punch/power output and still runs almost cold to the touch for the first few hours, then just moderately warm. these are sleepers that have a robust power section, and mostly outdated pre-amp, input sections. really good for using as independent amps as well, with a separate pre-amp. cheers!

Not collecting dust in their boxes. Great machines!

I would part with the DSP-A1 and tuner is the right party (and price) came along.

Hmmmmm, I decided to buy the Lexicon CP-1+ over the Yamaha DSP-3000. I think that it has more options and flexibility than the Yamaha does.

Yamaha toys are nice, but the one that I was never really impressed with Yamaha power amps. I got to listen to one yesterday, and it had the power, believe me, but it lacked the authority, the punch if you will. It sounded a little bit thin. I don't know if it was the amp or it's age, a defective cap, o whatever-but it didn't sound right. Just my two cents.

PS-Stereophile reviewed the Lexicon and favored it over the Yamaha DSP-3000.

I love them too, especially the old Titanium finish series (w/ real metal faceplate)!!! My first big audio electronics purchase was a Yamaha RX-730TI receiver with a DSP-E300TI unit. What a cool unit the DSP is/was!!! It was a tweekers delight with several user programmable parameters and YST processing for the surrounds. It was great to pair with a 2-ch receiver in order to get surround sound for HT (I would think this alone would make AKers like the concept, they can add it to their beloved 2ch equipment and get surround sound for occasional HT use...my attraction for sure). This unit has 5 modest surround amp channels, Dolby Pro Logic, sub out, and several soundfields of course (I always liked the "Disco" program for enhancing the deep beats of 80's type music on my 12" woofers and sub).

My second purchase was a "beast master" DSP-A700TI, which I still us today. It is similar to the E300 unit, except adds a substantial stereo amp for driving the main channels. I agree, the mains 2ch amp is very substantial sounding given its rating, which is the same comment I would make for the receiver as well.

Lastly, I could not pass on a deal to purchase a DSP-E492 unit in order to try Dolby Digital processing with my then new Yamaha Dolby Digital DVD player.

I have a DSP-100/U that I bought new back in 1988 or 89. It is not an integrated amp, but rather a stand-alone, outboard digital soundfield processor. I used it for many years in my main audio rig along with an MX-35 4-channel amp to power front and rear effects speakers. Some of the soundfields were pretty amazing. It's sitting in my garage at the moment, but I hope to someday put it back in use with a proper AV set-up.

thanks for the replies. I really like the church sound field on some recordings. The phono section as well as the amp section of the a1,1000,2070,3090 are all good to go. This was the type of high current amp they used to make in the old days. with the introduction of the rx-v2090 things changed a bit. they took the rail voltage up to get the higher wattage specs, 100 wpc instead of 80wpc, but a look under the hood tells that the high current capability was cut down in exchange for more peak current, and higher wattage specs. If you want to try one of these fine machines, and I suggest you do. (look at the above comments) then stay with one of the models that was mentioned as well as the highly reknown dsp-a1
 
The later models are practically bulletproof.

I can't tell you how many time I've shorted out the speaker wires on my RX-Z9. The amp display notes the problem and the amp simply shuts down. Clear the short and it powers right back up as if nothing ever happened.

Bulletproof!

Hey, I just got a DSP-A700 too! And an M-70 (200wpc power amp) and a C-70 (matching TOTL preamp) and a tuner (matching T-70) and a cassette deck (um, nothing too special but it's pretty good too, prob won't get used much at all) and I have the big ass RCX table top remote for the DSP too!

I literally just got it into my house yesterday and haven't even plugged it in yet, was more excited about the M-70 and C-70 obviously (by the way, I got all of this stuff for free along with a pair of infinity RS-6b speakers, turns out one of the woofers is shot (overheated) but hell, it's all free LoL).

I had no idea that the DSP 700 had built in power amps, esp. decent ones for the mains. however with the M-70 that is kind of moot. I'll prob set it up for fun with the m-70 and a couple pairs of cheapish wall mount speakers on it's 15wpc surround amps to have some fun :-)

cheers!

A modified version of "The Roxy Theater" is my favorite music mode. (Been there too.) :music:

can't wait to try it! I'm going to set it up between my c-70 pre and my m-70 power amp.

QUESTION about the dsp systems: does it's effect add verb etc to the mains as well, or just leave the mains intact (original stereo) and add the effects in the 4 surround channels?

if it does nothing to the mains other than volume and getting the source signal to use for other processing, does it put the mains through the a/d d/a before it's output to hte mains preamp outputs? if so then that kinda sucks. I do'nt want my audio going through a/d d/a just so the level matches that of the surround channels.

Although I guess if I use my c-70 preamp to set the level and leave this at unity then I could skip the mains output of the dsp completely (direct from c-70 pre to m-70 power amp) and instead use the 2nd level controlled (inverting) output from my preamp to drive the dsp as well and just drive the 4 surround speakers with the dsp unit. that way my mains are still pristine while all signals get the same level control.

I can't imagine (but I could be wrong) that inverted outputs to the dsp box will make much if any difference since the phase of everything could well be off anyway with different amps and my surround speakers will have no low end as well.

I'll be setting up my surround channels with some cheapo little speakers I have lying around... nice that the 700 I have has built in amps, but I feel bad that the built in 60wpc mains amp won't get used since it's a way better amp than the actual surround amps. wish I had better speakers to try the surround channels with but I need all my mains (EV, my customized jbl/energy bookshelfs, and my hopefully soon to be complete Infinity RS-6Bs), will have to do my famous craigslist free thing to see if I can find something a little better.

by the way, the 700 is HEAVY... I honestly think it's heavier than the m-70

cheers,
Don

The DSP-A700 is an "ahead-of-its-time" selectable 5.1/7.1 ch device. Fortunately, Yamaha provides pre-outs so you can use your own more powerful power amps if you so choose. The surround channel amps are a bit weak, but Yamaha offered matching modest surround effect speakers at the time as well. I tried and never really liked the full 7 channel mode for HT as the mains are run in bypass mode in this set-up. I like the simpler 5 channel mode so that the cool front DSP effects all are channeled (pun intended) through my better front mains. The .1 sub channel works, but not so well by modern standards (crossover at 200Hz). I still use it to my sub, but I use the sub's x-o to restrict to 50-80 Hz range.

I agree, that remote is crazy big? Not a one hander.

ok, that info helps me out a lot thanks! I'll try this baby out. I do have other amps I can use for the surrounds (my technics and scott receivers, both decent vintage late 70s stuff, the technics in particular is an over achiever with very excellent modern sound while having a ton of vintage real power and warmth as well imho, the scott is overly warm, much less modern).
