I did try the shorting HDMI plug on my unused input on the MK2 today but really didn’t hear much difference, maybe the images were slightly more distinctive, but very subtle. The big difference was the SR Galileo power cord. That really brought the MK2 to life. There were more richness, bigger soundstage, and much better dynamic contrast. The MK2 really loves this power cord.
Shorting plug on USB seems to wok best and ii2s shorting works in Synergy with it. About same level of improvement between D S nd DS MKii.
My MkIi is really really great after Antero mountain software. I will listen more the decide where additional tweaks might be needed. It takes a few days then one gets more critical.
I am going to try and sort out which i2S input is noiser next. Then loser gets the shorting plug. On DS number 2 was noisy. The MkIi they switched positions of rear panel feedthroughs. Wher i2s 1 is inboard like i2S2 was on DS.
So do you think I2S 2 is better than I2S 1 on the MK2? I should maybe use the I2S 2 for my PST and short the 1 instead?
USB cables really makes a huge difference with the MK2. I went overboard with mine. The ChordMusic USB cable makes every other one I tried sounds dull and lifeless, but for budget, the Inakustik Referenz is not bad and the one to get.
I have not tried I2S2 yet on mkii but plna to tonight. I like to baseline a few songs then switch and replay. I am sure best one eill be one away from noise maker. But Ted did more thoughtful pwb layouts on Mkii.
Give I2S 2 a few days of break in. I used both since day one. I have not swatched the cables yet. But my streaming has improved to really close to PST. It is using I2S 2 with Firebird48 instead of Dragon48 on I2S 1.
