The SE and XLR outputs are separate. I like the balanced better.

My unit did that once. Volume control did not change volume. If somehow Dac is in integer mode the upsampling and attenuation will not work.

I only used the AES, RCA, and USB. In my setup the AES was the better sounding. Did not try optical. Did not mesh with USB, seemed a little light weight. I blamed the Sabre Dac chip and USB. I think the Infinity may benefit from one of the USB "bandaids" available. The Intona is what I wanted...

  I paid around a grand for my Infinity. It works too.    There seems to have been some issues with circuit boards. But the multiple firmware requirements made this project so difficult for them. Not sure they are certain what firmware is needed for all the Pulse, Pulse SE, xdi, Inifinti, and...

Not sure you will hear an improvement. I like cables that are just long enough to reach. No extra length. Tried several and really never heard any changes. Volex, Eupen, and a couple generic cables. The medical grade Eupen are nice for digital gear.

Any sightings of the two mono amplifiers?

Does anyone have the updated Matrix firmware on a stick?

My laptop is only used for OBII diagnostic software and updating software. Plan on sticking with 8.1. The Main firmware now shows up as 3.0. Seems to work fine.

I submitted a ticket last weekend and received the firmware yesterday. So five business days. This is a good trend. Hopefully all the open tickets will be addressed soon. All I included is it is an Infinity and serial number.

I guess I still have v1.5 firmware. My unit shows 2.0 Main. I need to look at my windows laptop to see what the firmware is downloaded on it. I use with a Mac.

  Just submitted a ticket for the latest driver for the Infinity X. Works fine with 2.0. Maybe 3.0 will flesh out the sound a little. Clearity is a strength, not as warm as I prefer as is. Hesitant to upgrade firmware, works fine with current firmware.

  How many here are running the 3.0 firmware. Mine shows 2.0 after update at few months ago. It is an Infinity X.

It seems the problem is the firmware is not the same for all the models. Larry may not know the matrix. I think the Infinities work with the latest firmware. The other models may not. The real answer is a firmware that works with every model, version, and vintage. I have an old (2009) FireWire...

What is the ticket to get it set up properly? Mine sounds a little thin.

I had forgotten the amps had shipped. How is it as a 2 channel amp?
