VOLUMIO soundcheck invitation for Hamburg, Germany

[judydudi]

The Elac amp is one of the best amps in his class tested by many trade journals and you call it a 'bad amp'...
We are going our independent way ... perhaps we come to Hypex or somewhere else...

Hi Judy,

Have you compared Daphile systems with I2S boards anytime?

Soundcheck 8

SC8.jpg (134.71 KiB) Viewed 4212 times

part I of Soundcheck, yesterday.
First i explained the six guests the advantages of volumio.

in the 'warm up' round we had a setup with three amp's to compare.
(allo said, the announced elac amp would not be great)
so we compared the Marantz PM6003 (used in the souncheck past), the Elac EA101EQ-G and the allo volt + D amp.
We used 3 ELAC FS 78 speaker pairs. The volumio primo provides the signal with a switch and a remote control to the three amps.
We realized very fast, that the elac did not sound as well, as the other. (in a blind check, of course)
The Marantz was more warm. the allo a bit more detailed. The group was 50/50 to decide which one would be best.
I decided to take the allo in the next round, the DAC competition, because we already heard most of the DACs with the marantz...

i'll come back later on, to write about the DAC round stay tuned...

Can some explain me some configuration ?
My friend have Allo Boss 1.2 , Allo Isolator 1.3 and RPi.He wants to know how to connect right ?
He have linear power suply and power bank

[judydudi]

... and our winner in best sound quality is : volumio primo !
very closed followed by the allo Katana THD board and DACBerry Pro.

Some of us also said that they would prefer the Katana Board in a certain genre of music, and in others the volumio player....
All of the tested boards were very good. no board disappointed us.

Katana v1.2 with THD stage and Isolator with Dual LPS Thel NT-25HQ-09
Volumio 'Primo' (on Tinkerboard S) with shipped psu
DACBerry Pro with one line of NT-25HQ-09 LPS
X400 DAC extension module, 19V IQaudio PSU
DACBerry ONE+ with one line of NT-25HQ-09 LPS
Mamboberry HD DAC+(crystek) & kali with mambopower LPS
Khadas gneric tone board on RPI 3b+ and ifi ipower
IQaudio DAC PRO with 5V allo dual PSU

volumio 2.555 was used in all setups. same playlist as before.
Piano 2.1 with Kali reclocker did not work in dual mono.
I was happy to see the new I2S driver for the DACBerry boards in this volumio version.
The apple pi was gone, because orchadaudio asked for his board to get it back.
Many thanks to allo, michelangelo, collybia and OSA electronics for the great support of the soundcheck.

We used the allo volt+D (Dual) amp, with the 19V from allo dual PSU.
Loudspeaker were the compact ELAC BS 244.3 (they are great)

The pleasure is always the come together and speak about what we are hearing.
When people are talking about " i was falling in the music scene", or "the sounds were frayed" ...

thanks for coming!

No comparison between boards? What happened?

[judydudi]

I think the most interesting point is
that with different people, different speakers and another amplifier
we still (blind) identify the same boards as best. (primo, katana). The DACBerrys come very closed to them and i'm sure, apple pi would be also great again with this setup.

[judydudi]
