DSJ & the Lush USB Cable


#1

Aloha from Maui,

I mostly use my MacBook —> Supra USB —> RUR —> Curious Link —> DSJ setup with Roon and HQPlayer. I prefer this arrangement to the Bridge II.

I’ve read a lot about the Lush USB cable. Is there any point in spending the nearly $300 to replace the Supra with a Lush given its all going to end up going through the Curious Link anyway?

Thanks

Shunyata will soon release a Sigma USB. $2000 for one of those. Sometimes you get what you pay for, even with cables.


#3

For that type of money you can get an USB to I2S converter which would bypass the noisy Xmos chip.


#4

Cables make a difference and some are garbage. Digital cables have one job = transfer data as flawlessly as possible. This can be measured.

Agree with cxp - for a few hundred bucks the I2S converter will provide a significant improvement. I never had much luck with the USB connection on the DS, tried a curious usb and regen combo and others. Not sure the problem was related to how much I spent on the USB cable. It’s possible but I found that a $5 toslink cable was better then any usb cable I tried - go figure.

Out of curiosity, what are the alternatives to the Matrix or the SuperDigital? Thx


#7

If you mean the Sonore ultraDigital - there’s also the Singxer SU-1. Good chance any of these would be a better sounding option than USB via a computer.


#8

Haha, yes, UltraDigital. Somehow got Super Dave mixed in there…

Do these I2S converters provide isolation from my MacBook like the Mirco & Ultra Rendu?

I do like USB though, better than Bridge II…

@dancingsea
Yes there is galvanic isolation and reclocking with Crystek 575 I believe.

Benefit of Singxer SU-1 is included power supply,

Benefit of Ultradigital is external power supply allows to to upgrade to a better supply. I highly recommend Sbooster Mk2 but this runs $350. However I tried the cheap Ifi 9v powering my Ultradigital and it still smoked my Ultrarendu powered by the Sbooster Mk2.

BTW I currently have the regen Curious link USB connecting my Ultrarendu and Ultradigital (stacked).


#11

Thanks for this feedback :pray:t3:

Do I understand correctly that your Ultradigital with thi ifi power supply, by themselves, smoked the uR with Sbooster - by themselves?

Does that mean one really doesn’t need the uR and the line, just the I2S converter?

And how are they altogether compared with to them separately?


#12

Benefit of the Matrix is you don’t need a PS - sounds good without. A lot better with Uptone LPS1.2. LPS 1.2 is a little more than Sbooster but may be a bit better. Tried an Sbooster with a Brooklyn DAC and didn’t like it much. Any of these choices will be a big improvement over Computer\USB,


#13

Uggh. You guys are making me question my ears :slight_smile: I have an AQ Diamond usb into a wyred recovery. I have compared a cd via toslink from a Denon 5900 to a ripped flac file via usb. I seem to like the flac better via my usb setup. It could be for a variety of reasons.

If I were to get a matrix and use the IIS into the DS - would you include the recovery before the matrix? Also -are you guaranteeing sound quality improvement? :).


#14

Did you try Mk2 Sbooster or just version 1 ?


#15

v1 never tried v2


#16

Don’t sweat it if you’re happy with what you have stay with it. If you get an itch to try something different most of these items have a 30 day trial period. Do some research and decide if it’s something want to look into.


#17

The Mk2 is a big improvement. Mk1 sounds dull and a little congested in comparison.

I am still waiting on my Ultra Mk2 add on. The noise baiter is very intriguing. Low noise going in is one thing, but being able to draw it out is another.


#18

What is your USB source ?


#19

Yes, the RUR would go before the Matrix… and what intrigues me about the Lush USB is that its supposed to be better than the AQ Diamond… at half the price…

I use an older laptop running win 10 w jriver. It is an i3 chip I believe. I have a powered usb hub hooked to the laptop w external hard drives Laptop is dedicated for music.
