Directstream Mk 2 observations

With the fuse change and absorbent tweak added, I have experienced the deepest soundstage ever from my system. Every singer sings behind the speakers on a live stage, some of them sing from more than six feet deep. I have never experienced it from DS in the past. MK2 is simply incredible in throwing me a deep and vivid presentation (among other things!).

I am hoping boost 2 from M-1. But the 3m absorber lid tweaks are the bomb. i must agree. The live Orchestra stuff is incredible. The Timpani thwacks deep in the orchestra then also naliing me with the orchestra hall back reverberations. Aaron Copelands Fanfare For Common Man had my wife running into the room to find out what I was playing

But Neil Young Harvest 50 year anniversary with LSO tracks are superb also.

Old Man Live so much acoustics of the hall. No LSO but truly hearing music like the first time. His voice and emotion. Not laid back but live.

I am surmising Ted listens with the lid off. So the RF and EMI i heard he did not. The 3M absorber lets us hear the masterpiece as Ted created. The lid lets it sll bounce around inside.

What exactly is the 3M tweak?

I started using the material on the P20. I had a sheet and a wild hair eureka moment on how to use it.

For MK2.

To use 3M Absorber on power cables this thread is full of info.

It solves noise issues in all sorts of cables and electronics. It impoves sound but also can be used on video equipment

Awesome thanks. I’ll start with the stock MKII and tweak as time goes on.

Going from a DSD JR so I’m expecting profound results. :gasp:

I never had pleasure of listening to a JR. But many say it is a fine DAC. I know you will enjoy the MK2.

I owned a DACJR (and MKI and now MKII) and it was a good unit, but it’s Achilles Heal, for me, was it’s relatively high noise floor. Each new design has beaten down noise to where it exhibits that blacker background we crave. The silence between tracks is deafening. You’re in for a treat.

Woot! Lower noise floor, what else?? You got my appetite going :smiley:

There are a number of posts on this forum from beta and production unit owners who have owned DACJR and DACSR. Expect better everything and judge for yourself.

woot! yeah ive read pretty much everything on the forums about it. I’m clearly excited.

Did you resolve this?

I just set up my MkII. Hopefully will have some time this weekend to listen.

A question about SR Purple fuses. I have one that I’ve been using in the MkI. Is there a consensus yet on directionality? Should the writing point into the DAC or outward?

“s” end should be inserted into the cap. Since yours is used, you can switch the direction after a few hours of playing to see if you like the other way better. Some people do.

My first post on the forum! I love the wealth of information and the civility!

Has any of you tested the MK2 plugged directly in the power amp, instead of using a preamp ?
I tested the BHK preamp at home and it made a huge difference when in the loop compared with my current dac directly connected to my M1200: bass control and dynamics!
Maybe I could kill two birds (current dac and preamp) with one stone (the new MK2), or is this just wishful thinking ? Thanks for your help!

In the menu, I see “Pre Emphasis” and “Shell Lift”, both set to “off” by default. I don’t see any mention of these in the manual. Any idea what these are for? Thanks!

Thank you!

Pre-emphasis controls how the DAC handles the preemphasis flag from CD’s. It has a bug at the moment, when it’s fixed it will allow you to always deemphasize, never deemphasize or automatically use the flags if available.

Shell lift allows you to disconnect the shell of the analog output XLR connectors from the system ground. Some interconnect cables will require the shell to be connected for best shielding, some don’t. You can simply try it both ways and keep the one that sounds the best.
