VOLUMIO soundcheck invitation for Hamburg, Germany

Postby rost21A » Mon Jun 03 2019 20:23

Hello
I think it's great that you organize these sound checks. I am always looking forward to the results.

I am not sure if Hypex nCore amplifiers have been already announced.
We have performed various tests with very expensive amplifiers (ASR Emmitter II, BAT VK-3Xi SE / BAT VK-200, Devialet Expert 120, Devialet Expert 200, Leben CS-600, ...).
The amplifiers based on Hypex nCore (nCore 400, North Acustics One SE NC 500, ...) were always massively better!

I strongly recommend to use an amplifier based on Hypex nCore.

Greetings and good luck

My company is about to release an amplifier that will have THD+N < 0.0009%.

https://orchardaudio.com/bosc

I could send you a sample for the sound checks. But not for this one.

I wanted to mention that, I forgot it in my last post.

I strongly recommend not to use a preamp in which a volume control is installed.
I recommend connecting the streamer directly to the power amp and controlling the volume in Volumio.

the new amp would have only one line-in.

so, we have two rounds, first with:

01 Piano 2.1 with Kali reclocker
02 IQaudio DAC PRO
03 DACBerry PRO
04 DACBerry ONE+
05 Boss 1.2
06 Mamboberry HD DAC+ Crystek v2
07 AroioDac
08 X400 DAC extension module

taking the best 3 boards in the next round with:

01 Katana v1.2 with THD stage and Isolator 1.2
02 Orchard Audio’s PecanPi DAC streamer
03 Volumio 'Primo' (on Tinkerboard S)
04 Khadas generic tone board USB DAC
05 DACBerry pro+ with osa isolator board

My Playlist ist now 8 track long ( Playlist on TIDAL ) with different formats (mp3 320 | flac 44/16 | flac 96/24 ) on internal storage.

Soundcheck is an independent and non profit association of HI-FI enthusiasts, gathering together to evaluate with double-blind methodology several Audio equipments. (typically I2S hats for Raspberry PI)

we heard in the past:
DAC:TauDAC-DM101 with TauOUT-TP101, Dial-DAC, HIFI Shield & HIFI Shield2, SabreBerry Z, JustBoom DAC HAT, Terraberry Dac 2, ApplePi, Curryman DAC
PSU: Raspberry, allo 5V3A, allo Dual, ifi Ipower, SBooster, Thel NT-25HQ-09, MamboPower
Reclocker: Kali, ApplePi Reclocker, 3R USB Renaissance, iFi iPurifier2
USB-DAC: iFi nano ione, Elac EA101EQ-G

Hi friends...
Yesterday we celebrated the soundcheck...
there were far too many boards, but with the new questionnaires and the tracks to the respective sounddiscipline the rating was easier.
allo kindly provided us with an Audiophonics PAS-125NC amp with a Hypex Ncore NC122MP.

from the first round we took the boss and the iqaudio dac pro as remarkable better.
in the second round all boards were better.
i added also the allo Katana SQ to the round.

so, the greatest pleasure has prepared us the new DacBerry pro+ board, followed by Katana SQ, Primo, Boss and Iq.
But wait. My local hi-fi dealer lent me Rotel RB1552MKII amp. So we were curious how these boards will shine on an analog amplifier ...
The amp has immediately made the mood in the room more relaxed... thanks to the warm signature...
Here we decided to place primo, katana SQ,Boss first, followed by DacBerry pro+ and iq...
Conclusion. Your optimal DAC board may vary depending on the sound system...
I will publish more from the questionnaires later on.

Thank you for your interest. I will continue the journey. :)
