Hi Mani,

you are right!!!!,**** but that depends on the frontend, such as turntable, tonearm and system!****

CD = 100% for SQ
LP 24/96 = 99,5% for SQ

Joachim

Hi,

Made some listening tests (for the conversion using Manis „favourite“  unit MR-2000S with the poor power supply)  with the Dave Grusin LP/CD. The identical source is the masterband on 1989.

1)   Best SQ  on my system is with the CD at 16/44,1, with the best resolution,  , a „wall of sound“ stage and a very, very small tendency to a harshness.

2)   Second best (SQ is 99,5% of the first)   is the highres LP conversion 24/96, which has more air, a „wall of sound“ stage, but less resolution by a small margin. A nice relaxing analogue sound with no listening fatigue.

3)   Last one on my system is the LP conversion 16/44,1, where the soundstage is in the centre mainly, much less air,  an accentuated bass and the SQ is a little grainy.

In other words, every system sounds different  due to ………. .

Hi Brian,

the adapters are nickel plated only. With voices (Caroline Henderson) the difference comes immediatly.

Joachim

Hi Brian,

thank you for the hint.

At first I will play with Peters "Blaxius", which didn't arrive until today.

Another item:

The BNC/RCA adapter from Lindy has the best performance, a nice analogue sound with a "wall of sound" stage. I tried a chromated 50Ohm adapter and the SQ got harsh and the sound stage fell apart.

Great voice and CD of this Swedish Singer

Hi,

the SQ of the previous (prior NOS1a times)  digitized  LP files changed with the „NOS1a replay“ considerable.

The last two days I made some tests with different sample rates using the  LP/CD from Dave Grusin (http://www.amazon.com/Migration-Dave-Grusin/dp/B0000001QL/ref=sr_1_1?s=music&ie=UTF8&qid=1415149201&sr=1-1&keywords=dave+grusin).

(for the cutting and transfering of the WAV- files I used AudioGate 3.02; declicking with iZotope3 – single band with a  low sensitivity at 2, and later converting WAV to Flac-files  with dbPoweramp latest rev.)

The best results/SQ  was achieved with a sample rate of 192Khz and a 24 bit depth.
There is a superb 3D room image (wall of sound) with a very smooth analogue sound without any harshness. The left/right separation is as usual.

--------------------------------
With the digital files the room image is a little bit broken/disrupted. The instruments seems to be played in different chambers (no wall of sound).
The kick drum, bass and cymbals are more pronounced  (maybe I have to adjust the subwoofers), and over a longer time the listening is a little bit exhausting compared to the LP files.

The SQ with both sources is amazing and it is difficult to decide what to prefer, and ...... the analogue source is on par, at least.

EDIT I: this post is in contradiction to some previous statements, but the reason is that I increased the SPL at XXH from -31,5 to -27dB and the system (speakers) behaves different, and
second the system is now "in phase", which was not the case for at least a year. Nobody (who I know) was able to demonstrate with a sample when the system is "in phase" and when it is "out of phase". 
The track 3 on the ISOTEK CD is such a test now, and I'm quite sure, that a lot of our systems are "out of phase", and that is a tremendous difference.

Hi,

the funny/strange thing was, that I treated the new LP,s with  „LAST“, and dubbed them on a magnetic band (Studer A810) and took  them in a shelf until now.
So I used the LP one time only, and now there are clicks all over, and with the washing machine the clicks are reduced.

In other words, the „LAST“ treatment procedure in the 80ies was not for the better.

Joachim

Hi,

since last year I’m digitizing LP’s which are not available on CD’S  (Jaco Pastorius and various MPS records etc.).

Peter wrote in the Forum  a couple of weeks ago that his copies of digitized LP’s sounds „suboptimal“, what I have to confirm (no cymbals, no bass, no kick drums)

Since two month I’m cleaning the LP’s  prior to digitizing with a washing machine (Gläss Vinyl Cleaner: http://www.audiodesksysteme.de/index.php?kat=10_17_15 ) and the SQ improved amazingly and I enjoy to listen to the old records again.

The washing process with the LP‘s is mandatory for a good sound!!!

Joachim

Hi,

the tour is a very good idea

Joachim

Hi Paul,

the highs?

Joachim

Edit: What is "hash" in audio terms?

Copy from Stereophile:

hash A very coarse texturing of the sound, characterized by a sharp-edged, spiky roughness. Caused by severe distortion with strong transient content, as from a grossly mistracking phono cartridge.

Hi Brian,

the RG 142  has a "stranded core" and the RG 223 has a "single core" wire and in my opinion the difference shouldn't be high.

Peters Blaxius is still "on the road" because the Finnish transportation is slowly sometimes/most of the time.

It is not my intention to upgrade the NOS1 (to a 75B) in the near future, because the poweramp cannot be modified with/to a 75Ohm inlet socket, AND the SQ is really great at the moment.

Hello Joachim

Not sure but why are you not using XLR Cables?
Is there any thread here explaining why BNC would be superior to even XLR? = NO

Speaking of XLR and Cables.... maybe people do not used them with their Phasure setup here not often.

Hi Michael,

there was a discussion in the German audio press about the preference of  XLR or RCA connections  appr. 5 to 10 years ago and the opinion was a "draw" between both.

I made a comparison between a XLR Nordost SPM and a RCA Nordost Valkyria and the difference was insignificant to my ears at that time and so I stuck to cables with RCA connectors.

Joachim

Hi Robert,

the amazing sound  of the NOS1 with a BNC cable connection to the poweramp is dependent on the NOS1 (Christmas is coming soon), because with other DACs (Weiss) I did not get the same results by far.

Prior to the 50 Ohm  BNC cable I used RCA cables from Nordost (Valhalla) and later on one from Entreq.

For a second hand Valhalla 1m RCA we have to pay at least € 1400,00 in Europe, and we get a first quality 1,5m BNC cable (RG223) for less than € 100,00.
