A stiff program you have had. Chapeau!

Ever thought about Audiophonics TDA1387 hat dac or the Audiophonics Ess9038 dac?

Thanks, you are right :)

14 devices were played... all prepared, for example with same sound level (+-0,5db., pink noise used...)
This time we used a different amp, so I think the ranking has changed slightly.

we took from the first round with Piano 2.1 with Kali reclocker,IQaudio DAC PRO,DACBerry PRO, DACBerry ONE+, Boss 1.2, Mamboberry HD DAC+ Crystek v2,AroioDac,X400 DAC extension module the boss and the IqAudio.
Here the boards were good, with strengths and weaknesses and very different rated.

The second round was with
Katana v1.2 with THD stage and Isolator 1.2 (RPI3+)
Katana v1.2 with SQ stage and Isolator 1.2 (RPI3+)
Orchard Audio’s PecanPi DAC streamer (RPI3)
Volumio 'Primo' (on Tinkerboard S)
Khadas generic tone board USB DAC (from x86 lenovo thinkcentre tiny)
DACBerry pro+ (RPI3)
Boss 1.2 (RPI3)
IQAudio Dac pro (RPI3)

Here, in this round all boards were rated first class.
Compared to the previous Soundchecks, the Katana SQ was rated better than the THD Version of Katana .
PecanPi. The Pecan Pie was inconspicuous, which means he has mastered all disciplines well.
Khadas was inconspicuous too.
Remarkably positively noticed, however, was the new DacBerry Pro+, followed by Primo, Katana SQ, iQ and Boss.
We took the opportunity and listened to these five devices again at a Rotel RB-1552MKII amplifier.
We have reduced the selection due to the short time available.
However, I think now, we should have listened to all devices again, since the order has changed again.
At the Rotel analog amp we liked Katana SQ and primo best, followed by DacBerry pro+ and iq...

I had then examined the two amplifiers in more detail. The transparency of the digital amplifier was really good, but the sound wallpaper seemed somehow flat. The analog amplifier had a larger stage and the sound had deep, magic. However, the centers were less pronounced here. The NAD C 268 is a good middle ground here that combines both. He might make you a bit too euphoric ...

see here a part of our questionnaire...

Hello Judy

I received several emails and forums request for more clarity .

I am copying and pasting the request :

"This experiment had so much promise. And I really looked forward to the results. But then undermined by what I struggle to even call a barely summarized list of findings. Let's see the data! ( I know you're not responsible for that. Just speaking generally.""

Hypex amp:
1. DacBerry pro+
2. Katana SQ AND Primo
3. Boss AND iQAudio DAC pro

Rotel RB-1552mkII
1. Katana SQ AND Primo
2. Boss (not really shure about this placement)
3. DacBerry pro+ AND iQaudio DAC pro

Sorry for the misunderstanding and not very clear placement. After all, it is not easy to re-enact as the whole group is.
It was slightly different for the individual. Our main point was the realization of the Dacberry at the analog amplifier, which was pushed behind the other two. hope that helps :)

As per request on another forum:
"Several metrics for each device was collected. I see no reason why totals, average, median, and standard deviation, for each category can't be shared for each device tested. What I read [again, ahem] 'barely summarized' is disappointing."

leo , i know allo did it too, but this kind of conversation is crazy.
I do not like to comment on statements of unknown that somewhere in the net uttered.
Maybe you can see that I try to improve the soundcheck every time. It is as a journey as i said.
The main thing of the soundcheck is the come together of music lover, listening to some great volumio devices and share the thoughts what they hear. The publications here in the forum are an attempt to summarize our impressions.
I am glad if some here can benefit from it. best, judydudi

I understand but for those that do not attend the soundcheck it is not easy to decipher the end result.

For example you say:
The PecanPi was inconspicuous, which means it has mastered all disciplines well.


But then in this list the PecanPi is not mentioned at all:

The two statements don't seem to be in agreement.

i think it's clear. We liked Pecan Pi, but we liked 5 boards better than PecanPi. we did second round on analog amp only with the 5 boards, because short of time (after 10pm), as i wrote before. PecanPi could have won round two, but we don't know now. I understand this disappointing. leo, we had a weak chain with the amp this time. I'm optimistic that next time your board will be shine as it is. Stay tuned... :)

When do you plan to do next sound check? I will see if I can get you the BOSC amp for it.
