soundcheck's Touch Toolbox 3.0

Factory SBT vs my TT3.0 SBT in the same system, side by side.
Shorter time between factory and TT3.0 than with tt -r and tt -i, tt -v, tt -k and all the restart in between.

System:
ML 383
ML 390S
Audio Physics Virgo 5

Any difference?

Well, yes, there was a difference.

First the Teddy Pardo TTouch PSU was connected to the factory SBT.
I did not expect this to make a very noticeable difference, but I was surprised. The main differences were greater impact and details in the bass and a calmer sound (less noise?).

Then it was time to check if the TT3.0 does sound different than the factory SBT when making quick changes.
Played some songs on the factory SBT and then switched to the TT3.0 playing the same songs.

The plan was at first to do many back and forth listening tests including blind testing. But instead the time was used to install TT3.0 on the factory SBT.
(We could have done blind tests, but those would have been to please the non-believers. And to be honest, I don't care if anyone don't hear the same as us)

The differences are on the details and precision. The revealed details gives the sound stage better precision and the placement of the artists/instruments are clearer. There's details in layer upon layer within the music, making the presentation more lifelike.

Thanks again, soundcheck, one more follower added

I'm back to the default TT3.0 settings.
This is at the moment the most real sounding setup, even if it may be too much for some unbalanced systems.
The big differences reported by some must - IMO - be a result of those systems beeing very unbalanced, chrashing due to small changes in the setup.

If your system goes from unbeareable to heaven with a change in prio-settings, look elsewhere than the TT3.0 to find who's to blame....

Sorry to butt in...

I'm just going along reading the posts, taking what interests me and leaving the rest.

I don't understand what everybody seems so uptight about and I can only guess what half the implied accusations/insinuations are really driving at.

I agree that some people(including myself)have gone off track a bit discussing HW mods but then again Klaus himself also included a few HW recommendations in his TT 3.0 blog.

In any case besides the endless buffer tweaking nobody appears to have much left to contribute regarding the SW aspect of the discussion.

Side by side testing:
A- SBooster BOTW - SBT - TT3.0 - default prio buffer 20k - modified Draka Ethernet
B- factory SBT - factory PSU - low cost Ethernet cable
both synced, connected to D-Link ethernet switch, digital out to V-DAC 2, LMS 7.7.0 with FLAC decoding on server.
Very instructive to switch quickly between setups without having to reboot and resume listening from start. Helps to get fresher cognitive memory of what you have heared.
Result? ........ +1 for those who argue that all hw and sw mods on the transport have little or no impact when played through an external DAC.
If there was a difference this was in the very fine details but nothing compared to changing speaker position for instance. Anytime I found something better on tweaked SBT, I came back to factory SBT and noticed it was also there. Now listening to factory SBT while writing and still enjoying music soundstage, details, tonal balance and so on.
This will hopefully put an end for me to the nightmare of the endless (and sleepless) tweaking quest of the holy graal of the perfect sound and finally let me enjoy the music.

Effects of priorities might be interesting to test as you go on at 20k.

Congratulations for finding a way to evaluate your system to your satisfaction and for realizing that it's about the music.

Klaus just called and told me how much he appreciates the hand job you're giving him. Keep up the good handiwork

Sigh...you're sinking to a new low of classless immaturity. Too wrapped up in mental masturbation I guess.

Well done - this is a discussion forum. Made up of hundreds of threads where people swap information, experience, hints tips and advice etc.

This thread like the rest discusses a specific topic - you've clearly been having trouble for weeks understanding that concept.

Your buddy SBGK suffered a fatal meltdown last night and clearly the propellor separated from his head in one clean action. Yours appears to be intact..for now, but it'll happen..

Can I refer you once again to a message that was posted by Klaus yesterday morning. Read it and follow because you clearly will miss the opportunity to blow smoke up SBGK's arse at every opportunity.

Sorry Marc, I was trying a bit of reverse psychology, trying to wind Klaus up so that he would hurry up and release TT4.0. If TT4.0 is better than TT3.0 then I want to know about the improvements and, like the rest of you, I don't want to pay for the priviledge. So come on Klaus pull your finger out.

I find it ironic that Klaus is complaining about the open source tweaking talked about in this thread when he has benefited from the open source nature of the SBT, what are his motives ? I suspect he thought he could sell his code to Logitech or others for a tidy sum and then we who have helped him develop it would be left with a more expensive Touch. Thanks Klaus.

I would like to provide herewith again a short straight feedback to Klaus and the community about playing TT3:

I don’t like to include other chain members (DAC, amplifier and speakers) for inculcating the sound, so this is just my subjective opinion regarding the differences of priorities on the same chain, without any blind test side by side: (not necessary at all if you have a good brain memory)

Setting: TT3 + SBT default priorities + buffer 4000
---> The sound, as well the treble, is well balanced with more accurate bass, the lower the buffer is chosen down from the default with a laid-back effect comparing the following on:

Setting: TT3 vanilla (buffer 3400)
---> Crisp sound, more in your face, highs through audible and also crispy but slightly more restrained bass but very accurate; bass is deteriorating rapidly in performance, the higher buffer is selected.

Anyway, the last setting is indeed closer to me, but here we are talking really of marginal changes in sound, nothing earth-shattering.
I would have had keep this setting but because of the unbalanced treble (left harsher than the right channel at 44.1 khz / 16: check out close at the speakers) which is possibly due to the low buffer setting at 3400 and the priority like PIDJIVEALSA with 96.

Therefore, I would like to ask around here again, if other people experience this same with vanilla TT3 regarding the unbalanced treble: if so, perhaps it would be a further improvement opportunity for TT4 ..?

By the way, please interrupt some arrogant statements that have nothing to do with this forum: not worth the time. This is all about TT3 and not a forum for further realizations of any kind.
