Dear friends,
Could you provide me your opinion/info on that old product? The new Mr. Meitner site is www.emmlabs.com His patents are there: http://patft.uspto.gov/netacgi/nph-P...&RS=PN/5329556 http://patft.uspto.gov/netacgi/nph-P...&RS=PN/5404362 http://patft.uspto.gov/netacgi/nph-P...&RS=PN/5388221 http://patft.uspto.gov/netacgi/nph-P...&RS=PN/5499315 |

I know, that Meitner IDAT uses a DSP-chip-based digital filter for continuous signals. This filter produces a normal squarewave shape, but switches to a filter algorithm optimized for transient performance on signals that are rich in transients.
But maybe somebody knows what receiver, DACs and symmetrical output stage were used? |

I'm using the Museatex Meitner Bidat with the Melior CD-D with full modifications from Museatex. (The Bidat allegedly replaced and bested the Idat at a far lower price.)
I find the sound to be on par with that I've heard from top of the line gear from DCS, Linn, Meridian, and ML. I have yet to pop open the Bidat, but will be doing so soon to add dampening materials. Hence, I can't address your specific questions. My understanding is the Bidat employs proprietary adaptive algorithms chosen on the fly. John Wright at Museatex might prove helpful... (My Bidat and Transport are on a Vibraplane with multiple stages of power filtration.) |

Here are some pics of the Bidat

Thank you, Peter! The receiver is SAA7274 and digital filter is SAA7350. Is it correct? I noticed two (!) Motorola processors.

Comparing to ML360S, the sound is more listenable and involving, more musical as some may say. It has a bit less refinement, but overall I would prefer Bidat.
My unit isn't modified, although it has Supermod done. That DAC certainly needs modifications to achieve full potential..
