The Macbook Pro is (I'd guess) abrasive blasted and anodized, it has a matte finish, very subtle texture and of course the lines are sexy as hell. An awesome computer in form and function.

I think the Matrix looks very nice, the form factor is nice, it's a good size and seems well built for the money - and I really dig the VFD. But the finish is a little too shiny and heavily textured for my tastes, and it looks sparkly, and I'm guessing it's painted or powder coated? If you offer a chassis kit to swap it into a black enclosure for a reasonable fee I'd be interested.

Overall I'm a very happy customer and would recommend it to others for sure. The only other nitpick I have would be that the volume control I think is linear, an exponential control would be nice, or even if the software is sensitive to how long its been turned and speeds it up the longer you are turning it; like a slow mode and a fast mode (sunfire does that with the encoder on the theater grands, its kind of nice).

Replacing the chassis is easy. It will involve 16 screws on the case, 4 screws on the board, a wire and a plug to the LCD. Whom wants to buy a new chassis please PM me.

When I first got the Matrix I wanted the volume knob to be like Sony's input knob on their DAT and MD units. If you turn it slow it changes by increments of one. Turn it fast then it jumps by five or ten for example. After spending time with the Matrix it's fine just the way it is. So easy to overlook something like the volume knob because I enjoy the sound so much.

Unfortunately after over 3 weeks i still haven't my Matrix :frowning2: Is there anybody who wait so long for his DAC?

Sorry buddy, s**t happens... This is the longest shipping for me too. Possibly because of the UK workers strike.

Mudshark,

Volume steps go from -90 to 0.

I have ordered many things from many parts of Asia and have never been taxed. I once had an item stuck in customs over a holiday and that was the worst.

Hi, great, so 90 steps, that's good, thanks for the info!

I am trying to decide between the Matrix and the Compass for a desktop headphone system (Senn HD650) that is fed via Toslink out of my computer.

Yeah, but I'm too stubborn

So, I'll wait for new delivery and try again.

Hi, some little questions...

1. Is the balanced out fixed or can I adjust the volume?
2. How is the construction and gain of the headphone amp? Is it solely opamp based, or does it have some kind of buffer? What's the opamp used?
3. Is the volume control digital or analog?

Thanks guys.

1. Both. Selectable
2. Construction of electronics is very good/ chassis is good but not up to par of other high-end designs but I rather not pay a $100 just for a fancy chassis. I am not clear of the technical aspects of the amp itself.
3. Volume is digital.

Thanks sunnybear, but you got me wrong on the second question.

What I want to know is which opamp is used as headphone amp and if the headphone amp section consists of just one or two opamps or are there any kind of buffers?

Next question: Which chip is used for digital volume control?

Thanks alot!

best regards,
bearmann

Headphone amp ON also sets outputs as pre-amp. Headphone amp OFF sets outputs as straight DAC.

OP275/OPA2134 opamps NOT replaceable. That's all that is listed in the specs. I do not know anything else about the inner workings of the Matrix.
