Am I understanding things correctly, that the analog outputs on the M108 are only mic preamp direct outputs and not available to use as playback outputs from a DAW?

That is correct. The analog output is a buffered balanced output direct from the mic amp. The only path for DAW playback is 2 channels via USB or the Dante option through the stereo DAC which feeds the headphone out or control room out option. It is a possibility we can do an 8 channel DAC option for 8x8 USB functionality, but that is not in the works yet...

Still quite useful for us location recordists who'll put one or two of these up to connect our microphones and drive a playback pair or talkback channel. I'm assuming that in Dante each M108 shows up as two receivers and eight transmitters?

When using Dante with the m108, you can transmit 8 channels from the m108 ADC and also receive 8 channels from your Dante network to the m108 monitor path. You can only select one pair of Dante channels for monitoring through the stereo DAC at a time though. This basically allows you to send up to 4 stereo mixes to an m108 over Dante.

Ah. Let me read that back to you. The M108 appears to Dante as an 8 transmitter/8 receiver device. But if I send 8 streams to the Dante card in the M108, I can only pick one pair (I'm assuming 1/2, 3/4, 5/6, 7/8 rather than say 1/7) for DA conversion.

Do I have that correct?

I was wondering if there is a sonic diference with your other 8 channel mic preamps or if they use the same pre?

Thanks

Just a friendly bump -- anyone have some hands-on experience yet with an m108 which they'd care to share?

I've read the available reviews that have been published so far, but it would be especially helpful to hear the thoughts of someone who does a good deal of location recording and has put the m108 through its paces in that regard.

Cheers,
Luke

Come over to the location forum... One of our regular posters was expecting an M108 this month.

I'm trying out a Grace Design M108 at the moment. I used the DI to record a Martin acoustic guitar. A pleasant result was achieved. I then recorded a vocal track with a U87ai and compared it against my Buzz Audio MA.2.2. The Grace was much clearer and had a beautiful top end. The Buzz Audio was thicker and did not open up the top end like the Grace. So far I have been very impressed with the M108.

I have an ma2.2 myself and have grace m101 pres. While not a 108, the grace 101 still sounds great but it does have a somewhat "hard" quality. My MA2.2 has a more open and dimensional sound than my Grace. Although as I said, they're not a 108 and it's possible that Grace has improved their sound with this new unit.

Does your MA2.2 have transformers? It sounds like you're describing transformer saturation. If you have them in your MA2.2, then only the TRS outputs will be transformerless. The XLR outputs will be transformered.

Later versions of the MA2.2 were available with Lundahls which are cleanish, but earlier ones were available with Sowters, which are heavily colored. I actually have an MA2.2 with the Sowter transformers. It's really great for tracking guitars because I take a feed off the XLRs and get dark and thick sowter color, and take a second feed off the TRS outputs and get an incredibly clean, open, and three dimensional sound and I can choose at mix time which I feel works better.

You'd have to check your serial number on the back to see if you have it. If you do, you'll have TX at the end of the serial number. But it still won't tell you what type - you'll have to open it and peek inside to see.

The Buzz Audio MA.2.2 I have is a great unit and I will not be parting with it. I purchased it in 2013. It has the lundahl transformers. I have been very pleased with it and it has been my go to preamp for pianos, vocals, string instruments, and bass drum and snare.

I recorded an acoustic guitar track with A U87ai through the transformerless outputs and compared it with a U87ai going into the Grace M108 (using the same guitar part). The MA.2.2 was fuller (this time it was not thick and not compressed sounding as it was through transformer outputs) but it required a hi shelve EQ to fit it in the mix. The guitar track from the Grace M108 sat well in the without any EQ. Both guitar tracks were very good. I get the impression that with the Grace it will be possible to record many tracks without them competing as much for a place in the sound space. Synths sound really beautiful through the DI inputs. My Rickenbacker 4001 bass sounded fantastic through it. For the first time I was able to capture a wonderful DI ed bass sound without having to apply any EQ to sculpture the sound. Up until recently I was using a Manley Vox Box for those duties.

Overall, I am very impressed with the Grace M108. I was not expecting this performance.

I ended up buying the Grace m108, keeping the Buzz Audio MA.2.2 and also getting a Pacifica and Aurora GTQ2.

My Coles 4038s sound lovely through the m108. The m108 has a setting for ribbon microphones. It certainly increases the level needed for ribbon microphones whilst not introducing noticeable noise.

The m108 sounds great on the following sources tested to date: vocals, acoustic guitar, toms, hi-hat and DIed bass and electric guitar.
