Mr miller thanks for answering some questions. Glad you are hear. I am with Tony and a few others. I have been actively shopping for something that does 24-32 io and doesn't have driver issues. The problem is that in order to get io without compromise, I have spend 10k or mod a older ad/da. The question Tony has asked a few times is important to me as well. The multichannel chips can do 8 channels or only 2. If the chips are only used for 2 channels the device has better headroom and other things that increase the sonic quality of the conversion. Can you confirm if you are running all 8 channels per chip or if you are doing 2 or 4 per chip? Thanks again. SSL alphalink and MX4.. 24 channels of great analog I/O and DSP. I got mine for less than 5K. No need to spend 10k+. |

My question would be how is the performance running unbalanced? That's where a lot of converters fall over. Agreed, Well, first let me preface that i feel very uneasy trying to explaining anything to the likes of Bob O!  First, I believe the 002 is balanced, but from my limited understanding, most gear is unbalanced once the signal is inside unless it's a fully differential design, i know most consoles are unbalanced, including mine, and i have an adcom gfa555 that is unbalanced, they both sound incredible..so? As far as i know (which isn't saying much), once converted to digital, balance/unbalanced is a moot point? So if you clean up the analog paths in and out, it can render the need for balancing as far less important. What i do know is the 002 is on clean higher current 18V rails which is great, and there is a lot of work done before and aft conversion to lower noise throughout, decoupling of the analog paths, the clock is rock solid, and less than a picosecond of jitter. That said, the bottom line for me was the sound. The unit went from an unusable neutered flaccid grey, to big, deep, wide, extended bottom to top height, and detailed, focused imagery. The reason i went ahead with the mod was because i didn't want to drop a ton of $ on something high end at that point, boy was i surprised at the transformation, i in no way expected it, and was thrilled 8) |

so ... has anyone used.. heard.. seen..or hit on one drunkenly at the bar?
I can find absolutely ZERO examples of this thing on the web. Not one.
Usually every man and his dog is shooting these new things out against whatever.. and then endless arguments ensue.
cheers

The reason I asked is because a lot of converters isolate the clock from the analog stage by running all analog circuitry differentially on two board layers. When you unbalance the analog signal, the performance often deteriorates a great deal.

I agree with Tony, it's so easy to order one or two converters at a time and compare them in your studio and return one or both before your credit card bill even comes due. Even if we are talking about $2000 converters there are plenty of smaller dealers who will send you their demo unit with just a deposit on your credit card. Same thing goes for mics. Even if you can't afford to demo them side by side you can record files on your computer for sequential comparisons.

When you unbalance the analog signal, the performance often deteriorates a great deal. There might be a brand or two that does the differential signal thing all the way through from the DAC I/V to the jacks, if you only hear 1/2 in an unbalanced mode, it will be worse. The designs I've seen schematics for usually sum the differential converter's current to voltage stage (I/V) to a single differential input opamp/low pass filter. That makes the signal unbalanced internally. Then its sent to a single ended to balanced output stage. Those designs you can use the outputs balanced or unbalanced and the conversion quality is the same. |

still no opinions/examples on these new MOTU units?
