M2Tech hiFace EVO

post #1 of 33
Thread Starter 

Anybody tried this little unit yet.  It looks promising on paper - power is now lifted away from the USB line.

I don't see anything saying that "power is now lifted away from the USB line"...only that AD USB Isolator chip can do that AFAIK. They say that there are pulse transformers on the RCA/BNC coax outputs, like in the 01USD for instance: http://www.musiland.cn/Attachments/200908/20090807_160615_120.jpg

 

The hiface also has one: http://farm3.static.flickr.com/2588/4151427046_fc5e520a83_o.jpg

"input for external supply (7 to 11VDC)"

 

Which means that it doesn't have to be USB powered.  Or maybe even can't be.

I wonder if I can pipe 13.8v dc (DC PSU output) straight into the clock - there is bound to be a SMPS wall-wart provided - not nice.

This does look exciting. Maybe overkill, but exciting nonetheless.

Well, S/PDIF is broken by design...slaving the word clock input to your DAC should be a major step forward quality-wise: http://www.gearslutz.com/board/so-much-gear-so-little-time/172143-spdif-vs-word-clock-question.html

Pairing my D7000 to a solid state amp - I can clearly hear differences in sound quality between different playback software! I can only conclude jitter is a real problem that needs to be managed.

post #8 of 33

oh yes, all the software players sound different...this is well documented too: http://www.cicsmemoryplayer.com/index.php?n=CMP.03Jitter

 

it takes rocket science to get a computer to behave as a good source, but when you start using a combination of low jitter software/hardware...it quickly turns into a PRaT monster :gnasher:

I thought this was not releasing until July or August?

 

Also, I have a few questions...

 

1. What is the "ST" connector for?

 

2. Do we need anything special to use an external word clock? Basically I do not understand the whole master/slave concept. Will my existing DAC work with an external word clock?

 

3. Any special PSU required for best sound quality, or would any 9V wall wart work?

 

4. Is this worth the upgrade if we have the hiFace already, or would we be better off going with the jkeny mod?

Marco has told me that it would be available in September.

I think you mean word clock.

oops, typo..fixed! anyway, what DAC's would allow that trick? I've never seen word clock outputs on affordable ones.

I just received my M2tech Evo from TweekGeek. Ships w a regular 9V wall wart. (I'll upgrade that asap).

 

Comparing it to my HiFace - the Evo is a significant step up in SQ. I run it straight into my PS Audio PW Dac. With the Hiface, there was no contest - my PWT Transport had way more depth, wider soundstage and more bass. With the EVO (Illuminati D60, XLR), the difference between the Transport (running I2S) into the PWD becomes MUCH smaller. (So much that my Transport is up for sale -lol). This is without "break in" and the standard wall wart.

 

If you have a fairly resolving system and running a HiFace, I would recommend giving the EVO a try.

There are updated specs with the input voltage.

 

Supply voltage: 7-11VDC (15VDC max.) 

 

I wonder if this means it will take a 12volt battery.  Even if it doesn't, rechargeable 9 volt batteries are everywhere and some power tools use small 10.8v Li-ion battery packs.  I think I will pick up one of these in this week or next.

 

I always felt I heard differences in transport but the differences were either placebo or too small to be worth investing in anytime soon.  Last night I listened to my LCD2s and found different transports were like.......WTF!

 

Coming from the Pioneer Elite 989Avi, the soundstage was more spacious at the cost of imaging.  Where the stock USB input imaged better and was not as "airy".  Kinda like one transport leans the LCD2s a little towards K701 and another a little towards HD650 - in terms of soundstage and imaging.  I wasn't listening for it, but it was immediately obvious...I never believe in digital cables, usb cable, etc...but now I'm not so sure.

finally I picked up the EVO today.

I've been using the HiFace with a laptop running WinXPP SP3 because it wouldn't work on the desktop PC running Win7 - due to some new AMD chips or something. the EVO works on the desktop PC flawlessly.

 

I'm stating the above because I don't know if the different PC, OS, etc...  have something to do with it, but I find the difference between the HiFace and the EVO remarkable. really good improvement in the sound. very, very pleased so far.

 

the system is getting better and better... lucky me. I wonder by upgrading the dac how much better can it sound...
