Hi Peter,

a description with other impressions, but the same meaning.

The acoustic bass on the Brian Bromberg CD sounds with "Custom" very detailed, unbelievable, but the sound comes from a "deadened" ( evacuated) room with less reverberation and deacay of the instrument.

The "resin" sound of the violin on the Naoko Terai CD is less accentuated.

If you have one CD with an acoustic bass solo and another with a violin you should hear the difference.

The Naoko Terai CD is a terrific funky jazz album, same tracks are good to dance. (Market Place (a Weather Report tune) + Rio Funk)

With socks only , no chance, but good luck . See You in the final!?!

NO, in that row a neck stiffness ................. .

Since most concerts are amplified today the best distance for a good listening position in concert halls is around 20m away.

At present I'm going up the ladder and stranded at 16xAP after a couple of weeks again (due to the rev. a).
Since the Ron Carter concert my priority for listening is ambience. (we do have to live with compromises)

Hi Peter,
this/yours is a very good description of the (Beta) “Custom filter”, which is the best with new details “raised” from digital music ever.

Made some additional comparisions between “Custom” & 16xAP, and raised my listening volume from -33 dB to -28,5 dB.

The only thing I’m missing is ambience. ( http://www.stereophile.com/content/sounds-audio-glossary-glossary )

A good sample is the CD “Naoko Live” from Naoko Terai. (3rd track “Black Market”)

With the filter “Custom” I’m sitting on the stage and with 16xAP the seat is appr. 25m away.

Hi,
in general it is difficult to get the same result/opinion of  a “software/hardware” test due to the different systems/rooms we are listening with/in and personal preferences.

1)   test of 1.186-i – Custom at 16x AP 
                              
replay of acoustic music/instruments such as

a)   first track on the Brian Bromberg CD
http://www.amazon.com/Wood-Brian-Bromberg/dp/B000FQJPBO/ref=sr_1_5?s=music&ie=UTF8&qid=1404651943&sr=1-5&keywords=brian+bromberg
and
b)   first track also on the Al DiMeola CD
http://www.amazon.co.uk/All-Your-Life-Tribute-Beatles/dp/B00E1SM5UA/ref=sr_1_3?s=music&ie=UTF8&qid=1404652122&sr=1-3&keywords=al+dimeola

There is a very detailed replay with an amazing resolution. A superb metallic sound of DiMeolas guitar strings.
You can hear the picking of the bass strings very, very clear. It seems that the recording microphone is appr. 0,5m away from the instrument. (Brian Bromberg)
I hear less reverberations/resonances of the instruments and 3D image as used too.

2)   test of 1.186-i – 16x AP       
The recording microphone moved away from the instruments (Brian Bromberg), so less resolution (different characteristic of the filter), better 3D image and more reverberations/resonances of the instruments.

3)   test of 1.186-i – 8x AP       
Best overall performance with a seamless soundstage, nice 3D image, instruments (acoustic bass and guitar) have body and a perfect integrated bass.

Joachim

P.S. We have an open kitchen/living room area of appr. 55m², and our listening SPL is around 70dB(A) only.

Yep.

Peter (not our Peter) wrote to tell me about the Eminent Technology Model 17 fan-powered subwoofer. It's all well and good, but I'd personally go for this one-off 60 inch subwoofer: "The cone moves 6 inches peak to peak under full-tilt output... Unfortunately, Tim and his crew didn't realize just how much acoustical power the sub could generate, and didn't build the vehicle to contain it appropriately. Even at less than 1/2 output, the doors were blown off the tracks, and the entire vehicle ballooned in and out several inches."

I'm ancious about our ceilings now.

I'm thinking about to ................ !

Hi,

After some tests with the different filters (rev. “e” & “g” ) the revision “e” (sent with the NOS1a) is with 8xAP the preferred one on my system.
Rev. “e” with 8x AP brings a seamless acoustic pattern, nothing protrudes. The soundstage is in a perfect balance.

Best SQ I ever had.

Joachim

Hi Peter,

got it. This setting is more pleasing for the speakers and has an impact of the location of the instruments in the recording studio too.

With 16x the piano was in the back of the studio, and moved now (8x) forward, which is more realistic. (Stanley Clarke Trio)

Joachim

Hi Mani,

yes, the filter works in 16X AP only. The sound (characteristic) of my speakers are from the "bright side". So, bad luck for me.

Joachim

Hi,

Bass is a very special story.

I owned the von Schweickert speakers “VR-5 Anniversary” a couple of years ago, and it was nearly impossible for me to get a satisfying bass in my room, and I moved the speakers for at least one month around in my room

I do believe Mani has to make some “body building exercises” with the movements of the speakers to get the right position for a good bass.

Joachim

Hi Peter,
made a test with the „Custom“ filter, and what amazing cymbals, detailed with the “clicks” etc.
But overall this filter emphasizes the highs too much on my system.

Joachim

Hi Arjan,
so you are on the road to …………… .

Peter wrote that an updated NOS1 needs no burn in , and so I should hear the full potential of the modification already. (bass and highs are amazing)
At present I’m going through my “library” and I hear details not familiar with. I’m still in the familiarization period with the NOS1a, but I can say already, the SQ made a tremendous step forwards.

In one week I will go from 8x AP to 16x AP for a comparison.

I see in your profile that your setting is without upsampling.

Joachim

Hi Mani,

The Isotek CD was the best what I found so far. The playing time is appr. 1 hour.
Peter will give us an advise how to repeat a track with XX, I hope.

Edit: On this CD is a track of 30min for systems with a subwoofer.

For all "Lee Ritenour" fans
