I agree with Tony as well. I'd rather over spec than wonder 'what if?'.

Understood, but we're talking 3dB for like 100$.. Anyway, I'll continue to research it. Lets take the technical stuff back to the secret project thread though.

OMG. Just when I was thinking about upgrading my 2 ch DAC. Thank you Svart and I agree with everyone else. I will gladly pay extra cash if I can get a better product.

It also looks like people are asking for the DAC options that will add considerable cost to the design. That's fine with me, but it'll add maybe 75-100$ to the DAC total to do a dual DAC/superfast opamp version. Since the difference between stereo and dual mono versions is only 3db, I might forgo the dual dac option and just retain the fast opamps. 3db isn't necessarily worth adding 75$ to the price tag I think. I'm 100% with Tony. The price point your at is ridiculously low already so I have no problems paying more. We're talking something in the lynx Hilo category if not better for 5 or 6 hundred bucks. No Brainer!! I'm in for one of each now

I really would like to be added for pure GAS - BUT i am already saturated with high end conversion and have to put my money together for a 24ch. DA in early spring...sorry. I will follow the project with high interest, but no order for me anytime soon...wish you all the best with this very exciting new product!

I would go for broke on the DAC too. Don't know if I can swing both right this second, but probably could by the time it is made.

I will do DAC for sure; let us know what you will do about Jim's and Tony's suggestion.

I think the DAC is a add on that goes into the AD case. You won't be able to have the DAC separate. If the only difference is 3dB of noise floor down below 100dB.. come on guys, get serious. If there is no other change in tone or functionality... really... whats the noise floor of your gear? Whats the dynamic range of your material? I often wonder about what I call "spec madness" in a few months, something else will come along that has .0000567 of a bees fart better spec on something or other. I will be in for a ADC and DAC at whatever you decide svart even just to support something like this getting off the ground. I will pay whatever the consensus is, but really someone explain to me in what scenario AT ALL the difference (at the levels we are talking ) that 3dB change in noise floor is going to make? cheers Wiz

This is the former Gearpimp / consultant Talking. 1 Don't worry about Hiitting RMAs price point, If you can deliver quality build sonics and deliver in a reasonable period of time, with what most would expect as normal communication people will pay. I see Benchmark, Mytek Lavry 1/2 rack as your benchmark. Your probably going to Stomp on that price point. 2. Normally I would say take the number of us interested and decide it by four, but here I would say think 75% are going to buy in the near future. 3 the plugin DA option sold 80% of all Apogee AD8000's but only about 20% ever bought the option. 4. I would humbly suggest a run of 20 PCBs, and a first run of 10-20 units. I think you can pre sell a run of 10, with the understanding that your not going to start production till you have 10 orders, I think if you price it right so that you can finance this and make some coin , the majority will support us! We won't have a problem if the price is lower or the design is improved over time that's what happens!

I'll buy one of each. AD with DA add-on. I've been looking at the R.M. for awhile, but I'd rather go with you. I'm in for sure.

BTW, any chance of 8ch converter happening if everything goes well? Just curious.

It's possible there might be a SPDIF to ADAT converter, which could take 4 of the stereo converters and bring them into an adat interface. That's the best that I'll be able to do. Multiplexing datastreams is no trivial matter, especially if it'd need some kind of way into a computer.

What concerns me is that no one seems to know precisely what makes the RM Superbeast so special. I haven't heard it, but smallbutfine and others have stated that the Superbeast is considerably superior to RM's other DAC. Maybe there's more to it than the additional 3db of noise floor? In the Hilo, the main DAC uses dual chips per channel while the monitoring DAC doesn't, and they claim the main DAC is better beyond the 3db of additional noise floor. From my point of view, this is one reason I'm hesitating on the Hilo. It's $2500 and they cheaped out on a couple of chips for the monitoring DAC? I don't get it, and I think it's affected the Hilo marketing negatively. They were hoping that the extra quality of the main DAC would be a vaunted feature, instead many are asking why the monitoring DAC couldn't be the same quality.

Multiplexing datastreams is no trivial matter, especially if it'd need some kind of way into a computer. That would be great! I just realized also that if you could eventually build a stereo ADDA with a built-in ADAT interface, you'd have the equivalent functionality of the UA 2192. A lot of people have lamented the fact that the 2192 is no longer available, maybe you could ultimately fill that void.

I will be in for a ADC and DAC at whatever you decide svart even just to support something like this getting off the ground. I agree with this sentiment, and I will also be in for an ADC and DAC. I'd like to compare them to my Burl ADC and my Dangerous DAC. Who knows, maybe the Burl and the Dangerous can be replaced. That's about $3500 of convertors, so I'm willing to pay whatever the highest quality options turn out to be.

I DO accept that it depends on what level you intend to play, but i'm personally reaching for as close to a 0 compromise set up as i possibly can get. Smallbutfine has already stated that he hears an improvement from the superbeast over RM's other 1794 DAC, I wonder what those differences would sound like comparing 32 tracks captured with a top of the line vs mediocre AD? I don't see the point of a compromise when you can have it ALL at an obscenely low price point less than a MBOX!! Quite honestly, i'm not interested in a piece of gear where the sound quality was compromised for a measly $100! really? So yes, 3db is totally worth it, not to mention the headroom gains from single supply's. IMO, It just doesn't make sense to bean count.. i mean don't we get enough of that with every company in the world? we have a unique opportunity here to help C earn a little $ while he gifts us with his formidable skills, and I don't doubt that if this thing is as good or better than RM's superbeast, Svart will have to quit his day job to keep up with the orders he's gonna get. Anywho, I'm really curious to see what dan thinks about his superbeast as compared to his BLA 002? I expect it should sound better, but i've expected that before, the BLA 002 is completely and uncompromisingly over built, with headroom for days, and it totally shows up in the sound. IMO, the reason others don't match up (i suspect) is that 95% of people who design mediocre sounding audio equipment would look inside that 002 and say "that was completely unnecessary, it only needed just this much to run properly, and that much to be shielded acceptably", that's what makes guys like JW special, he's got the rare combo of amazing electronics engineering chops and dumbo ears, he takes it to the extremes, and will be the first to throw something away if it sounds pretty good. edit; i wrote this before lesC's posts...which are dead on imo 8)

Just part of that post tony ...
"I wonder what those differences would sound like comparing 32 tracks captured with a top of the line vs mediocre AD? "
to keep it in context of what I was musing .. .that question would be better written as
"I wonder what those differences would sound like comparing 32 tracks captured with 3dB less dynamic range below 110dB on comparable high level AD?"'
thats my point. That they guy has already done a bucket load of design work , and I don't think its a great idea to get him to re do that, up the cost for the difference of that kind of spec.
Of course, YMMV.. and as I said, I will go with the consensus...
but what about tomorrow when XYZ convertor company comes out with a better one... more dB s lower... 8)
cheers

I think svart spent most of his time on the AD side? But I don't want to get into hypotheticals about what might come out tomrw, the stuff we're talking about is here today, and the bar has been set by RM, Chris can and should do as he sees fit, but in all honesty, to shoot underneath the bar is a mistake IMO, and means I'll be thinking of how I can get my hands on something better. I've been shooting out converters for about a year now, they are not at all close to one another ime, in fact they proved to be strikingly different.

Well, they just didn't care.
...No, of course they did care. Tried to get away with the lowest noise floor available at that time...

The problem is that after reading countless audiophool websites about DACs and who likes what, it's pretty much a crapshoot to guess what people will complain about. As was brought up before, even if I make it to the best the IC will allow, someone will complain that I didn't use a specific color PCB or something. To that end, I'm going all in. Dual PCM1794As, etc. It's gone way beyond the price/performance balance now, so nobody complain that the DAC upgrade board costs more than the whole ADC/chassis does..
