That's the thing about oversampling and delta-sigma switch DAC's. When you make the leap over to R2R Ladder you gain detail, clarity, sound stage, pronounced bass, realistic transients, instrument timbre, and decay. However that white noise that was once equipped to every aspect of sound is no longer there once you NOS it. There's no guessing, filters, switch noise, etc. What you end up with is something incredibly analog and reminds you of vinyl. Being able to go sharp but without fatigue. That's why NOS/R2R is so great. It's not just treble that can fatigue a person. When you switch over to the Spring you realize it's every sonic detail yet now it no longer feels force. It's so natural to the ears. It only gets better. I switched from the Spring to Pavane and gained a little more sweetness.
Do give I2S a try. You'll bypass the receiver thus improving jitter and digital noise further.
Thank you for the reply. I am beginning to understand now what all the hype over R2R is all about. I am exciting to try I2S and DSD.
I would like to hear your impressions between i2s (Singxer) and direct USB to the Spring.
I'm highly considering purchasing the Sonore microRendu/Uptone LPS-1 and going AoIP with JRiver because of course after I posted I had no noise issues with the USB connection, I started getting drop outs from time to time. I'm also going to revisit the SU1 as I feel I should have spent more time with it.
Does anyone here use JRiver>microRendu>SU1>Spring in their chain?
I dont have the exact configuration you are asking for but I did have an extended demo of the microrendu in my system:
Roon >HQP>microrendu (with LPS-1 power supply)>SU-1>DAC (Luxman)
The microrendu + LPS-1 was an immediate improvement over my low powered i3 powered pc acting as NAA for HQP. I am not one for hyperbole when it comes to audio but the microrendu + LPS1 made the music sound so much more organic and involving. I am sure the big improvement the microrendu gave had a lot to do with its better usb implementation than my el cheapo pc.
