Even though looking back, compared to others I have listened to or measured, this DAC had its various imperfections, it has been my constant companion on the computer workstation. Through it, I have listened to hundreds of hours of music, edited my share of audio, evaluated pairs of headphones, and run various 'experiments'. Like an old friend, you get to learn (and at times even appreciate) the quirks. To this day, it remains my 'workhorse' DAC. Why, you might ask? Because it has 2 nice big volume knobs.

One for speaker output, the other for the headphones. Simple as that:-).

If you look back at my of this DAC back in 2013, you'll see that I generally liked it. With my perspective today, though I believe much can be improved (everything from channel/volume control balance [apparently fixed with later edition which also incorporates the DSD feature], J-Test could look better, noise floor cleaner, etc.), it was the hyped up 'symmetric upsampling' that was perhaps the most bizarre let-down.

Imagine a digital filter that acted as a brick wall at 15kHz! Certainly made the DAC sound 'mellow', but in a bad, inaccurate way.

A new software update which brings U.S. Cellular LG G3 US990 software version to US99023a is available now through LG Mobile Support Tool. After the Update, Your device runs Android 5.0.1 Build RX21Y. The king of fighters xiii save game. Cellular LG G3 US990 owners should receive the OTA update notification starting.

Despite rumours of a fix to the firmware, nothing happened after I reported this anomaly. Until late 2014 by the looks of it. Cabbage patch dolls and witchcraft.

And I wasn't aware of this until this past month. As I had previously mentioned, one of the joys of running a blog is the opportunity to interact and virtually 'meet' some of you out there.

And Raul from Europe got in touch and informed me of something I was unaware of - ASUS offers an! Despite this kit being listed in Europe and Asia ( from Germany for example), it seems to be MIA here in North America. Product stock photo. With Raul's generous assistance, I was able to get the kit contents shipped to my doorstep. As you can see, it's all rather simple.

A couple of DIP8 bipolar opamps and behind the opamps is the DIP8 EEPROM (4Mbit/512KB, ) which contains the updated firmware. A real shame that this could not have been just a software firmware upgrade. Note that this kit costs ~97 EUR (~$110USD) plus tax/shipping. The most expensive parts are the opamps. If you are looking at just acquiring the, they're about $45/piece retail currently. Very expensive opamps indeed (watch out for eBay fakes)!

So, that's basically $90USD for the opamps, and ASUS is charging about $20 for the EEPROM, the main feature of which being the ability to play DSD64 via DoP. Let's see if this is worth it. For today's segment, we'll just look at the features brought on by this EEPROM upgrade.

'Opamp rolling' is another topic altogether and I think deserves its own post (Part II) another time especially given the cost of these MUSES. For those doing this upgrade, remember that it's not just a swap of the EEPROM in location (1) below.
