Hi,

with less acoustic vibrations (from the listening room) you get
less jitter and
the SQ improves from both units located in the basement
(PC + DAC)

Hi,

if somebody is interested see:

I'm using the Prof. Edition for $ 49,90 without any problems since years.

The plus of this program is, that the last setting of XXH will be copied as a backup to the HD with every shut down of the PC.

Hi Mani,

there are not many possibilities left.
My proposals/route:

A) disconnect the PC from the power line for appr. 10 sec.
B) have a look into the BIOS for the RAM to ensure ..... .
C) proceed with booting and see what's going on.
D) If nothing helps, W8 has to be installed again.

kind regards

Joachim

P.S. A Happy New Year to all forum members from Finnland

Hi,

lowered the (driver) USB Buffer size from 4ms (since a week) to 8ms (back to the previous setting on the laptop)  and there are improvements (using Blaxius) with

A) $1 USB cable - a better 3D image
B) YFS cable - more "sounds" 

Joachim

Edit: Everything sounds normal again with the YFS

Hi,
now I do have problems!

A)
- Peters  impressions about the YFS cable in conjunction with the Blaxius can be confirmed.
- The disadvantage of the $1 UBS cable on my system is, the depth of the soundstage is not present.  A 2D image only, with the YFS a 3D soundstage is there (and nice voices), but  .... see Peters comment.

B)
- I exchanged the Blaxius with the “old” RG 223 and played with the YFS cable. The SQ is similar to A) with a $1 UBS cable, but with a 3D soundstage and a slight harshness in the voices.
- Replay with the “old” RG 223 and the $1 UBS cable. The 3D soundstage is gone and a slight harshness in the voices**is present** too.

At present the best compromise in my system is the YFS USB cable with the RG 223.

The “expedition” for the best USB cable with the Blaxius goes on.

Joachim

P.S. I wish you all a Merry Christmas and a lot of amazing music listening sessions.

YOU ARE ALL  ( in a positive sense )

Joachim

HI,

have a look under "Performance" and then scroll to the bottom where you see "Ethernet"

Joachim

Hi Peter,

great writing!!

Vibrations: What about the trafos inside the NOS1?

Joachim

The main point since **NOS1a** is, what PC configuration produces the best SQ, and everything else (components) follows this judgement.

A) PC system with an internal PS
or
B) PC system with an external**linear** PS

Joachim

Hi Coen,

The XXH settings I'm using are "weird", 8x AP only, no XTweaks and replay in "Attended" mode only. This settings do not favour the SQ from the angle of the hardware, but there is nothing strange during the replay, no ticks, nothing, a clean sound only.

The laptop is not as fast as ............. , but the loading speed of the tracks it is quite accepable for me, even with 192KHz/24 bit files.
I just tried to play tracks in "Unattended" but this mode doesn't work, so for this situation the CPU needs more power (and RAM).

What I expect is, that the external PS favours the SQ, and therefore  "low demanding power" components are essential. Such a PC should work when reading Peters comment here: http://www.phasure.com/index.php?topic=2937.msg31238#msg31238

The Intel Core i7-4790K processor (or Xeon E3-1241 v3 or Michaels Xeon type) should meet the requirement, and 16Gb RAM is a must.

We have to wait for Michaels report about his PC assembly. (hopefully before Christmas)

Joachim

Hi,

From my experience with” battery powered” frontend units/components this concept with the external PS (from CA and http://www.phasure.com/index.php?topic=3045.msg32944#msg32944 ) will enhance the SQ compared to our present “high powered”  PC configuration.

The SQ with my “under performing”  laptop (with an external switching  PS)  is the best  I ever had.  For a test I will order the” HDPlex Linear Power Supply” (< € 300,00 ex Hamburg).

Joachim

Hi Robert,

you are right!

Joachim

Nobody saw this article since 2010!?!

Hi,

this cable is quite expensive. Did you compare this with other cables?

Joachim

Hi Robert,

will try a battery mode during the day. I don't know if the XTweaks results for Time stabiity (not stable) and Time Performance Index (not the best) will favour the SQ. I will see (hear).

Thanx for your hint.

Joachim
