Similar temperature in Taiwan, I have mine DI-20 for long time now and kept it on 24/7, I do turn it off overnight once every few months.

I had IFI iUSB3.0 between MacBook Pro and DI20 90/98M and didn't hear any difference, I would spend money on better cabling.

Thanks all for the input, at this point I'm leaning toward to USB to Coaxial converter since switch/hub can potentially degrade both sources. But I am toying the idea and experiment converter and hub/switch see if I can hear the difference.

Help please, I have both MacBook Pro and Nvidia Shield tv pro and DI-20 only has single USB, how would I connect both USB to DI-20? by hub? splitter(if it exist)?

I dabbled many DDCs including Singxer, Gustard (most buggy), M2Tech, and few others, DI-20 works the best in my system and don't think I will replace it anytime soon. I have nothing against Gustard, but due to previous buggy experience with U16, I would just wait for more real world reviews.

I've been using DI-20 with 2013 MacBook Pro, Audirvana, Itune, Apple Music, and Tidal, even ran Dirac live processor, DI-20 never gave me issues. Only glitch I can think of is to turn off and on few times to get sound after DI-20 was disconnected or powered off.

Still using GPSDO clock with DI-20 90/98M, haven't got around LPS for both GPSDO and DI-20, GPSDO still out perform internal DI-20 clock.

Many of us ex-u16 owners went to AudioGD DI-20 and never look back, and your C-16 will work perfect with DI-20. But price of DI-20 is much more but you are getting more.

What's everyone's experience on Parallel and Serial? For me Parallel sounds lively but a bit harsh, Serial sounds darker but smoother. MacBook Pro/Audirvana USB >DI-20 90/98M/GPSDO Clock HDMI > Micromega M100

Still rocking 3.993 with Ext. GPSDO, very rewarding experience.

I got the DI20 90/98, I can assure it's much better than U16. I personally thinks it's a lot of money for DDC, but worth every penny.

Oh so you're saying some of the GPSDO ext. clocks have an antenna to use as a GPS, but most don't use it and it doesn't seem to make much difference anyway, right? And which GPSDO ext. clock do you have...

I personally happy with my GPSDO, and the antenna needs to place next to window doesn't really bother me. All name brand clock don't uses GPS, and most of 10mhz clock users here don't use GPS, therefore, I don't think GPS is necessary.

Sorry, I mean I already have a really nice conditioner and power cable. I'm using MacBook Pro USB to DI20+GPSDO clock then I2S/HDMI to my Micromega M100. I don't have other Audio GD goods other than DI20 so can't say for sure about the sound signature. I did own Modi 2 multibit DAC for few...

I got mine DI20 90/98 version last week. Previously owned U16+ GPSDO 10mhz clock. DI20 blew away U16+clock combo. 90/98 version cost under 600. HE version comes with better power supply and etc, but since I have good LPS and power cord, 90/98 version I thought was enough. I can tell you that...

Not sure how much is the used U16/C16, but if it's anything close to around 500USD, you should serious consider Audio GD DI-20 90/98M.The DI20 itself sounds way better then Gustard combo and you can always add ext clock later.

Tinny piece of my son's Spiderman lego set, cheers.

Just got mine DI20-90/98M yesterday. As soon as I opened up the package my heart dropped as the back panel indicate 220V and I needed 115V. Luckily quick call to May and solve the issue of opening the panel and flipped the switch. 2013 MacBook Pro>DI20>GPSDO 10mhz Clock>Micromega M100 with...

Hi yall, about to pull trigger on the DI-20, since I already have nice LPS and power cord, would I still need HE version or 90/98M should do the job. Furthermore, I have IFI micro iUSB3.0 between MacBook Pro and U16(sold), is iUSB3.0 still necessary with DI-20?

I did try with 2.0 USB hub, ifi micro iUSB3.0, upgraded all my USB and HDMI cable to Wireworld, and even got a nice power cord for the U16 (it did improve the sound), however, little bugs still remain.

Late 2013 MacBook Pro with USB3.0, lip-sync delay and dropout sometimes, plus EXT clock revert back to INTL often

thanks, but sadly my MacBook Pro only has USB 3.0

too bad no new firmware to address the bugs, otherwise for the money U16 is hard to beat

I make sure my U16 is on EXT each and every time I turn on my system, unfortunately, U16 will revert back to INT often for no reason.

is anyone here using IFI Micro iUSB between PC/MAC to DI-20? if you do, what's your opinion? is it necessary or its over killed?
