yes, I am afraid we do, hahahahaha

Stupid people

NOT TRUE!
You guys go into hibernation every so often (I guess during break-in periods), then pop back again a couple weeks later with 10 kilos of supercaps wired together and rockin' the house!

Anyway... congratulations.. especially the DIY power supply application is very interesting.. thanks..

Hey Dmitry,

Long time no see! Very nice to hear from you!!! You are way too kind

Glad my modded MX-U8 still is in your possession and still sounds very good! It had to travel a lot, first from China to Maastricht - The Netherlands, and then to Moscow - Russia!
And yes, in between there happened a lot with my beloved MX-U8 VERY glad you still have it and appreciate it's sound and build quality!

You never know, maybe I will start my own business, as I did before in 1991. Audio business is not an easy one, though I'm playing with the thought to build UltraCap powered
streamer/dac with Transient DAC Two modules. In that case I need to start a business again. Transient, or "ALL Engineering" or "Metrum acoustics", they only sell to OEM.

About ΛΓienStreamer, it still needs burn-in....... Last weekend had a few demo sessions which weren't as supposed. Saturday afternoon sound went kind of dull. This is
behavior I am aware of during burn-in. Need more time,,,,, But, unbelievable, that this happened after around 600 hours of burn-in. This is the first time I noticed something like this.
Maybe it is because of the silver RCA's I used, Silver tends to need MUCH more burn-in than copper. Not sure though.

The people listening to the ΛΓienStreamer last weekend all came to the same conclusion that in terms of 3D placement, it was UNHEARD of. Just at the top-end it needed opening again...

We will wait for that to happen


Cheers!

We will

Sound get dull!!! yes,dac dc 0.5v magnetized the output transformers(Alex tell me) I think this is the best config,without couple cap or any extra stages.
Now I listen other dam1 modules 4 pcs single ended,with solen couple caps,toshiba j fet basic stages improve in out resistances.powered 4 lt 3042,2x5v u cap psu for master power.
sound almost the same ????? small diffrences....or big?
can enjoy!!!important!!!

How many thousands of dollars did this build cost you?

 

[abartels]

Mine about 2....at least, closer to 3....

some haha.....

 

[abartels]

Yeah, Balazs, you are a commercial wonder..... you seem to be some kind of sorcerer to me.....

High quality NEW and UNUSED 100F 2.7V ultracaps alone do cost $10 each, easily.....

in my case:

120 ultracaps at $9,15 > $1098
64 HQ relays at $4,50> $288
pcb's, screws, standoffs wiring etc: $250
DC/DC converters - timer etc.: $25
Enclosure + plugs/sockets: $120
FIFO II +Isolator + RPI kit: $400
DA-M1 modules: $350
2x 19VDC adapter: $20
Outputtransformers: $100

Adding those it already is more than $2700. Didn't include shipment and taxes / duties......
And, a lot of small materials used to assemble all.

And last but not least, about 6 weeks of work in total....
