FS: Asus STX II 7.1 pcie with MUSES op-amp upgrades

Recommended Posts

Item: Asus STX II 7.1 24-bit 192Khz pcie soundcard with MUSES01 and MUSES02 op-amp upgrades in original box 
Location: Lower North Shore Sydney
Price: $400 firm
Item Condition: Used
Reason for selling: Upgrade HT amp so using HDMI audio now
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info: The standard Asus STX II 7.1 is $449 from most retailers. This was then upgraded with 3 x MUSES01 and 3x MUSES02 opamps on the Left, Right an Center Channels. and the Muses8920 were put on the side L & R channels. See pics for current op-amp config. The opamp upgrades cost $350 themselves and made a significant improvement over the standard opamps, which are also included.

 

This is a surprisingly high-end sound coming from a sub $1000 device. I would recommend not using the stock drivers, but using the UNi Xonar Drivers. The ASIO drier with low latency DPC is rock solid and provides excellent results. http://maxedtech.com/download/uni-xonar-w10-1825-v1-81a-r2/ I can get the latency down to 8ms using 24-bit multi-channel with these ASIO drivers. 

 

If like me you had a reciever that could not do the high definition audio conversion (DTS-MA. Dolby TruHD etc) then this is a perfect solution as you lan let your computer decode through this card and then input through the multi-in on the receiver. This solution has work well for me aprat from the fact my Denon ACV-1SRA was having difficulty driving 5 Dynaudio 4 Ohm speakers at higher volumes, so I found something with even more power than the Denon and went for that.

 

I still have the original box as pictured.

I did think about doing a shoot out with my Meitner MA-1 DAC by installing the card into my music server and linking it to the main amp (I was using this for 5.1 in my HT setup in the lounge). I have not had the time to do it though so I figured better just to pass it on. Its served me well for the last couple of years

 

For an off-the-shelf sound card it is very impressive, and the opamp upgrades definitely take it to another level again.
