for all undecided - here is another great reason to come to the soundcheck :D

Oliver from muc89.com was so generous to spend us two DAC boards for raffle. (Thank you Oliver)
It's a big chance for you to get one of these tricky ES9023 SABREberry Boards.

are you interested, what we did yesterday ?

Oh, we had a surprising evening...

But let me start at the beginning.

I had eight guests (3 women, 5 men) including Sergej Sawazki the builder of the TauDAC DM101.

And we had 10 volumio devices on the table. 5 boards for the RPI zero with RCA and headphone jack and 5 ‘king class’ DAC boards for the RPI2/3.
Due to a shipping delay, boss v1.2 and 502DAC pro did not come in time so we had:

IQaudIO DAC zero, JustBoom DAC zero, SABREberry zero, pHAT DAC, DACBerry ONE zero
all played with the allo 5v psu.

TauDAC-DM101/TauOUT-TP101 powered with the BOTW P&P ECO 9V from Sbooster
TERRATECHNOS – Terra-BerryDAC 2 powered with the THEL NT25HQ (2x5V)
Mamboberry HD DAC+ with Crystek clock powered with the mambo power supply
Piano 2.1 (dual mono) /kali with the allo dual power supply
IQaudIO PI DAC PRO powered with the ifi iPower

All boards where prepared with volumio 2.323 with three looped internal tracks and autoplay plugin:
Bob Dylan - Oh Mercy - Man in the Long Black Coat (96/24) (thanks Emilios for suggestion)
Leonard Cohen - You want it darker - Traveling Light (44/16) (thanks Stefan for suggestion)
Pink Floyd - The dark side of the moon - Money (96/24) (thanks Michelangelo for suggestion)

Turning on the masterswitch, all devices starts simultaneously.
After switching ~15min between the lines we start talking about our experience.
We where talking more about feelings and emotions than in a technical language.
After sharing some hints, we came back for a short listening.
Then we decided, that we like most the JustBoom board, just next to the DACBerry ONE. IQaudIO and SABREberry on place three. The pHAT DAC had problems with the bass from Leonard Cohen.

Turning on the ‘king class’ boards - we immediately thought ‘this is a step in a higher class’ (is this a group euphoric experience). We did the same as above and spoke about that some boards make a wider listening room, with other the room is more narrow. Also with some boards we thought just to be with the musicans, with other we felt a distance to them. These feelings differed from the participants to the boards. In fact that personal preferences differs, we decided to like the piano 2.1/kali bundle most. This board was just followed by the IQaudIO and TauDAC Setups. The mamboberry HD+ was great, played also everything fine but was inconspicuous (no magic soundlover present?) The TerraBerry DAC2 did not meet our imaginations.

The last step this evening was a direct comparison of the TauDAC DM101 with the JustBoom zero.
To my amazement some prefer the JustBoom for listening. Does it turns everything upside down?

We where surprised after realize what happend here...
So, every taste is different and very personal. And what about having the best DAC board and the other equipment does not meet the same level of quality. There are breaks in the the system. At the end, there is no winner, because it always depends. My thoughts are, if you are looking for the best DAC, you have to compare a bundle of DACs in your home and see where is your heart going to. (what about a rental service for a test bundle?)
And the winner is for shure VOLUMIO, because with this beautiful tool, we could come together to share our thoughts on music, with music.

Thanks for everyone following my musical journey, thanks for your listeners in the soundchecks, and thanks
to you Michelangelo, Emilios, Sergej, Oliver, Oriol, Michael, Ioan, Gordon, Stefan, ...

small addendum to our select:
we also said after a third listening, that we found piano 2.1, IQaudIO and TauDAC equal good.
And also some of us definetly said, that there favorite is the TauDAC.

Hi Judydudi.

I am very surprised that terraberry is not among the best. of the best I have only heard piano 2.1, but terraberry dac 2 for my ears is much higher (if you use your mode dsd to piano 2.1). in any case I'm glad that piano 2.1 is at the top, for my calidsd price (with kali) is the best dac you can do (with permission from Boss).

Regards

Hi judydudi
I agree with Jazz on the superiority of the TerraBerry DAC. I think you were using separate power supplies to DAC and Pi, is that correct? Did you use PCM to DSD resampling mode?
RPi 2b // Terra-Berry DAC2 // Hypex UcD180 // Bi-amped OBs with Visaton B200, Goodmans 15", Neo3 tweeters.

HI Jazz and jonners,
Thank you for your interest. It also surprised me.
I closed SW1 and SW2 for PCM to DSD conversation. Besides, I have used 2 separate linear power supplies. THEL NT25HQ (2x5V)
and the USB terminator, as you can see in the photo. 125h burn in time.
You know, the Mamboberry was on Amp CH1, Piano2.1 on CH2 and TerraBerry on CH3 (IQaudio CH4, TauDAC on CH5), maybe it has to do something psychologically.
If you expect something and you find it, then the thing next to it is more uninteresting. euphoric matters. 'Ah yes' .
Another issue is the volume. I set each DAC to 100%. and I was glad that it sound very similar. But in fact it was not 100% the same.
Maybe it's like red and white wine lovers. this time the red wine lovers where less present.
Hope that helps to accept the confusion.

comparing allo boss with allo boss (v.1.2)

so, you can't go wrong with a allo boss. it's does have a great sound and i think most people will like it.
i was curious, if the new allo Boss V. 1.2 will be different as the first release.
We found, it has the same soundprofile (clear, bright, detailed and a bit euphoric). switching back and forth from channel 1 to 2, we did not found a really difference.
Sometimes we where sure, the new one does have everything more direct, so a bit more from everything.
We where using the allo 5v psu for both boards. The new board was connected to the new 5v USB jack.

The soundsystem here is used by therapists. I have given them an allo boss for their practice and they are really happy with it :D

I think that you are doing some really important things with these comparison sessions. At the end of the day, whatever it costs, whatever the name on the badge, it's how YOU hear & enjoy your music that counts. Keep going judydudi :)

@ Judydudi (Jens)

Please continue this extremely interesting series of soundchecks!

How about doing a comparism of the DAC/AMP combos available (HifiBerry Amp2 / iQAudIO DigiAmp+, etc..)

Would be happy to contribute with my IQAudIo DigiAmp+ ...

Jens (same name and also from Hamburg)

Lieber Jens

Thank you for your interest in these soundchecks. :D
right now i am working on a 16 port HQ audio switch, controlled by the volumio web interface.
I do this because i was limited to 5 input lines with my amp.
i also found out, that sometimes lines have different volume levels...
so my plan is to come back with the next soundcheck in march/april.

Comparing the amp HAT's ? why not. i have both IQaudio AMP's, allo VOLT amp, DACBerry AMP+ and i have had the justboom AMP.
The problem here is that i dont have a switch, remote controlled for the loudspeaker connection. Any Idea?
kind regards, jens (judydudi)
