The recent/April issue of Vintage Guitar glowingly reviews the $1500 MR-1000, and it's lesser version, the MR-1, at $900.

Anybody here lucky enuf to have test driven one of these yet? |

I have read about them but for my blood and purpose it is way over the top in price. I'm sure it is leagues better than what I have but purpose is everything.
What is 1 bit technology ? I thought we were going the other way to 24 bit ?

I read some pros and cons about it on www.gearslutz.com with many questions about such as yours, Tony.
For my purposes at this time, nothing beats Mini Disc, so this new stuff will have to come way down in price for me to really consider.
But, it may already be obsolete, with HD/Blue Ray taking over everything. |

1-bit technology equals pristine fidelity
1-bit recording is the latest advancement in audio, and has been adopted for use in the critically acclaimed SACD recording format. It offers a frequency response of DC to 100 kHz and dynamic range of 120 dB. This uncompromising fidelity, low noise floor, extended dynamic range, lifelike imaging and analog quality depth has been praised by top experts. But there are other important advantages to the format that are of benefit to all recording professionals, regardless of their tracking platform.
Future proof flexibility
Today’s state-of-the-art 24-bit converters use high-speed 1-bit conversion to capture audio, using real-time decimation and other processes to present the data in the desired bit depth/sample rate format. The beauty of the MR’s bitstream format is that it uses the original 1-bit data, without the need for the other processes. What comes in comes out, with no manipulation needed.Today’s state-of-the-art 24-bit converters use high-speed 1-bit conversion to capture audio, using real-time decimation and other processes to present the data in the desired bit depth/sample rate format. The beauty of the MR’s bitstream format is that it uses the original 1-bit data, without the need for the other processes. What comes in comes out, with no manipulation needed. As files are converted and reconverted between various bit depths and sampling rates, there are possibly degrading effects, depending on the sample rate conversion algorithms. The critical issue is that files mixed and mastered in today’s state of the art resolution may be insufficient for tomorrow’s formats. Archiving your final mixes and masters in a 1-bit system allows you to bypass these issues, and preserve your music with both the highest fidelity and in a more “universal” format. That data then can more easily be converted at a later date to the bit depth/sample rate format of your choice without compromising the integrity or fidelity of the data. You can even convert to newer formats that will be adopted in the future, be they multi-bit or a further migration to the 1-bit format. (Source :Saved By Tech)
1-Bit Digital Audio Amplification
1-Bit technology is an innovative digital amplification system offering high-fidelity playback combined with highly efficient use of energy in a very compact size. By converting analog signals into digital signals that can be processed, a 1-Bit amplifier virtually eliminates sound deterioration that normally occurs during the transmission and amplification process of conventional analog amplifiers. There is a considerable difference between amplifiers processing analog signals and those processing digital signals. Analog signals transmitted and amplified by analog amplifiers suffer signal noise and degradation. 1-Bit amplifiers, however, transmit and amplify a pure digital signal stream generated by a seventh-order delta sigma modulation A/D converter, which takes background noise out to frequencies that surpass the range of the human ear. By processing these digital signals instead of analog signals, 1-Bit amplifiers eliminate the sound deterioration that plagues analog amplifiers and provide more complete, high-quality audio sound. |

A bit more interesting,
1-bit amplifiers employ a simple switching operation, giving them several advantages over class-A and class-AB analogue amplifiers with the same output power. Compared to conventional amplifiers, power consumption is approximately half, while heat radiation is only one-fifth, allowing 1-bit amplifiers to be one-third the size. Compact and energy efficient, 1-bit amplifiers shatter the conventional image of amplifiers being bulky and unsound from environmental and economical viewpoints.
I think I'll sell my amp while I can get a good price for it. Tone will be in the 1-bit |
