110V AC, otherwise interesting.

Transistors amplifiers tend have a very Tight "firm" bass - where as Mosfet amplifiers tend to loose that leading edge impact but have a wider more "organic" sound-stage with no hint of harness.
I believe the Bass "softness" its more the fault of the MOSFET output stage then the tube...
John, please remember you have clients highly sensitive to leading edge bass impact and not so for sound stage.
...Sound stage is, for more than 90% of the music I play, the result of an audio engineer, producer and sometimes musicians, mix decision.
It's an artificial setup. I can be pleased with the result, but it's not what I appreciate the most.

Soundstage, although allegedly an artifact is a good indicator of timing and coherence. Good transient response, instrumental separation, harmonic structure, note decay all tend to go hand-in-hand with good 3D soundstaging and pin-point imaging within.

You could make a trip 10 years in the future and return with some vacuum field transistors :0)
No, it's soft. You might like how it represents the low notes, but it's far from being 'tight' in the bass. I love how your set-up sounds but it's not anything like tight in the big sand-amp scheme of things.
cuko,
There are two basic grades of MDAC2 the L1 (which is the entry level unit) & the MDAC2 L2 & L3. The L2 & L3 should have identical audio quality but with differences in functionality (basically the L3 includes an Analogue to Digital Converter (ADC) and lossless Wireless link).
While its "fashionable" to offer high quality PSU - my experiences with the original MDAC is that an improved PSU made only a small difference - the audio quality improvement the PSU brought offered poor value for money.
Based upon my experiences with the MDAC & upgrade PSU, I felt that to bring a "step change" in audio quality required a new design - hence the MDAC2 project was born.
In addition the the L1, L2 & L3 MDAC2 versions you can also order at the time of manufacture (when you pay the last "At Cost" PCB installment) premium Vishay Bulk foil resistors for critical locations in the audio signal path - at this time I cannot say how many resistors will be required and how much this option will cost until I've built and listened to the design.
The L2 & L3 will be fitted with Bulk foil resistors in the most critical locations as standard (and hopefully the L1 if the PCB budget allows) - so the above option uses the Bulk foil resistors in more locations in the analogue circuit.
Finally at a later date there will be a upgrade PSU PCB that replaces the MDAC original PSU board. This PCB will be offered after the MDAC2 mainboards have been shipped - and can be DIY fitted by the owner. This PCB improves the isolation between analogue and digital sections of the MDAC2 design, which should also bring a small improvement in sound quality - the icing on the cake...

Hi john, i'd like to upgrade my mdac so tomorrow i'll send you the money by credit card on the lakewest mdac2 website. Please, let me know at which address i should send the mdac, what kind of upgrade is avalable now and how many days do you need for the upgrade. Sorry for my bad english...
Thanks too a little chinese ECC83 I now have drums and bass back .
Downside is I'm going cross eyed with detail again !
TAMP John? Have I missed something?

Did you see Jack White at Glasto ?
John,
I know this has been an issue, but my left channel is down today. no crackling, just no sound. I powered on/off 3 or four times, Unplugged the whole thing for 30 minutes, re-loaded A10 (Mac), then tried the headphone jack, both channels work and sound great, but when unplugged from the headphone jack, it goes back to Right channel only. If I switch the interconnects the opposite amp/speaker works, but the one connected to the left does not.
Any suggestions?
