I have been on Special Mode for a couple of hours. It's frustrating to find the noise-free spot*, but when it works: Oh, my, oh my - the sound quality takes Red Book into new territory where mankind hasn't set his fot (ear) before!

It's like the final CD veil has been liftet. More bloom, more inner detail and more transient details.

------------

*The combination of Latency and Q1 seems to be interactive. The Q1 setting working with fex. 512 latency, doesnt necessarily work with 1024 latency. I have to scan the Q1 between -4 and 30, each time I change (reduce) the latency.

Also a setting works fine for one song, but next song in the playlist is heavy distorted.... In fact, it's hard to find a combination which gives noise-free sound from a full album. Right now I have the following combination (latency 1024 + Q1=13) = Q1 parameter = 1022

The gain in SQ is well worth the work, though!!!   yahoo

One more note regarding searching for Special Mode optimum settings:
Re-reading the Download and release notes I realize all factors are mentioned by Peter.

If you havn't found your noise-free Special Mode settings, I urge you to re-read "the manual" written by Peter. It seems also that both Processor Core Apointment and Priority schemes must/can be changes to get noisefree Special Mode.

Hopefully Peter will make Special Mode more automatic in use.

What do you think I have just been doing, eh ?

It is not 100% equal to what you talk about, but the 90% will be sufficient for most.

Several times in the past, we felt the present version to be the "best ever", and we asked Peter to go on with the user interface and get out of "Beta-mode". Then he went on and made the next version even better sounding. Again and again. I am glad you didn't respond to our crying in the past! LOL

I also love the SQ improvements that special mode provides in my set-up where I'm using a synchronous AES interface to my DAC.  But as I said in another post, IMHO the AES interface is the weak link in my system.  Why?  Because sound quality is compromised by: (1) PC latency, (2) clock jitter, (3) noise and (4) cable geometry.

Peter's special mode show that reducing latency improves SQ.  I have proven that reclocking and electrically isolating the AES output from my Lynx card improves SQ.  And I have also proven that different AES cables sound different and better. 

IMHO, a DAC with a properly designed async interface should offer superior SQ assuming the rest of the DAC system has been designed optimally (i.e. power supplies, output stage, etc.) and alleviate the audiophile from having to screw around with these other variables. 

BTW, the new Antelope Zodiac Plus DAC will ship on April 20th.  Should be interesting.

I've replaced my Weiss AFI1 firewire interface with an RME AES32 PCI card. I forgot just how much I love the RME gear - the hardware and the TotalMix/Digicheck software. I appreciate the simple things, like having a properly terminated BNC wordclock input, which is so important when you're slaving the interface to the DAC, like I am.

Also, with Digicheck, I can verify that QAP adds extra HF information, smoothing the drop-off above 22KHz. (Interestingly, I'm measuring QAP at 23 bits, not 24!)

Another benefit is that my Special Mode Q1 value using my humble Atom-based PC has come down - I can now play with QAP at around Q1=160. But I agree with pedal in that finding a 'stable' value is difficult.

Just wait a bit. I'm improving the sound here.

If you could make Special Mode less hardware-intensive, I'd be a very happy chappie...

Hey Mani - What if Peak Extension is unticked ? does it make a difference ?
(it's diificult to reason myself how things work out, which is because of the integration with the Normalized Volume, but if anything it shouldn't make a difference scratching)

Thank you,
Peter

Hi all,

Firstly a big word of thanks - Peter you have made yet another fantastic player upgrade  clapping

I wonder if anyone can help, I am trying to get my M-Audio Transit to run in Special Mode. I am just getting "slow motion" music for all of the Transit latency settings and XX Q1 settings I have tried so far. Has anyone managed to work out settings for the Transit or Empirical Off-Ramp that allow Special Mode to work ?

Given how much better Engine 4 sounds I am really keen to get engine 4 special mode going as well.

Nick.

With Peak Extension ticked = 24 bits
With Peak Extension NOT ticked = 23 bits

Is this what you expected?

Mani.

PS. It's good to have Digicheck back!
