Been away for a bit - what's the latest firmware and what benefit would it bring to my MDAC over v0.99 (which is what I have right now)?
Also, any rough timescale for the MPAX, John? I know that you've probably answered this somewhere recently but buggered if I can find it...

I got a second MDAC now ... this way, when I send one back to John W for mods, I'll still have one at home ....... Looking forward to the MPAX ....
I think the big advantage of a touch over direct connection is that the touch is wireless and you can run many of them simultaneously. It also runs stand alone , no server required and does not mess with bitrates etc..
As to the chap that asked about the Brio amps vs Audiolab , well I have had both the 8000 and the 8200 Mb's in my system , I feel the MB's beat a Bryston 4B ST and the 8000p's were pretty good, both very "truthful" amps , so if you want a "romantic" sound , they aren't for you.
JohnW , I have a question for you , A local chap , now deceased built what is called a "constant Z attenuator , its a passive pre , remote controlled , What exactly is "constant Z"? and what are it's advantages. I have opened it up , see a ton of chips but no attenator (like an alps) ....
PS I think the best feature in your software upgrades is the ability or delete filters for comparison purposes ...
Input impedance can effect the sound quality due to loading of the source device plus cable effects - likewise output impedance can effect the SQ due to cable and input stage loading effects - having the impedances constant should in theory remove a potential variability in SQ as you adjust your listening level...
Do you expect the MAMP to drive Martin Logans when bridged? (if my understanding of bridging is correct, each amp will then see only half the impedance, so the current demand could be huge!) - I don't think I'm going to need the power for my Summits, but I quite like the idea of placing the amps behind each speaker, or even perching them on top of the bass bin - may look cool... I think they will make an interesting comparison with my EAR890.
John - load impedance effects on well-designed modern kit ought to be absolutely minimal. When you adjust the level of a signal, the biggest single variable as far as sound quality is concerned is the human ear's changing characteristics with varying level...Fletcher Munson etc.
Question for John, If you would be so kind.
I have had a an M-Dac for just over a week (from Movement Audio Poole)
Front Panel now shows "No Comms" and has ceased to function.
The unit will be swapped for a new M-Dac so no problem with warranty.
Just interested to know what could have caused this.
Unplugged laptop HP Pavilion DM1 (to use at my daughters wedding)
Returned home, plugged in same USB lead and now "No Comms"

My first post so forgive me if I have breached protocol.

No Coaxial connection? I thought, that was better!
Hi JohnW,
What stops you from having bigger heatsinks with more surface area in your design?
The MDAC is Clock master (the Transport is slaved to the MDAC clock by the second optical link, so any jitter introduced by the optical link is irrelevant at the point of audio conversion - but very importantly you gain the benefit of galvanic isolation afforded by the optical connection (With USB this is very beneficial as it isolates your audio system from your EMC (RF) noisy PC / USB Host device)...

Hi John,
With 2 MAMPs, will it be possible to use one amp per speaker, i.e. in a monoblock style configuration, or use one to drive the highs and mids, and another to drive low freqs, or all of the above?
Do you envisage much of an SQ improvement in using 2 over 1 in either configuration?
Many thanks,
James
Sorry to bring this one up again but when performing the bitrate test, it seems to be fine all the way to the end where it reads that the test passed and then immediately after, says that the test failed?!? Is this normal behavior or do I have a problem somewhere? Anyone else experiencing this?
Cheers,
Vin.
maybe I can update your unit during the CES - if I go this year...

Well I'm intending the MAMPS will drive my ML CLS11z - these are the worst amplifier load ML have ever inflected - so I'll discover how well they cope in Bridge mode - if they work well with my CLS's then there should be no problem driving your summits...
The MAMPS have 10 output devices per channel - peak current should not be an issue... protection is currently set to kick in around +/- 45amps - although higher shorter term peaks will be allowed... I'll hopefully soon see (hear) what this translates too in real life operation...
Can you Bi-Amp your Summits (rear Bi-Wire terminals)?
