I have use/listening the Shiga CD transport (vicol audio testing version) with the following DAC :
CS4398 :
24bit/192kHz DAC CS8416+CS4398+CS8421+Transformer Up-sampling,USB, DIY | eBay
AKM4398:
http://cgi.ebay.ie/ws/eBayISAPI.dll?...E:L:OU:IE:1123
also DAC Assemblage with pcm 1702 (the one on partsconnexion)
Parts Connection Assemblage DAC-1 D/A converter kit | Stereophile.com
Interconect vicol audio silver/gold ,
Speakers : Triangle Antal EX , BEETHOVEN BABY GRAND , Triangle Quartet and Nuova Opera Seconda

my top listening with SS amplifier (Vicol audio Quasar amplifier) :
1.CS4398
2.PCM1702
3.AKM4398
my top listening with TUBE amplifier SE (GU50 final pentode class A and 6n5p srpp in front) :
1.AKM4398
2.PCM1702
3.CS4398
mytop with listening Tube amplifier PP (6P3S PushPull amplifier with differential 6N9s splitterin front and EF86 as the line in) :
1.PCM1702
2.=3. CS and AKM sounds almost the same

There where some test also with some Wolfson WM DAC but i was not on site on that listening sesion
and I cannot say how it sounds .
I am on the GB for ES9023 DAC so soon will be testing this DAC also with vicol audio Shiga CD transport..
Remember : the top is made by my feelings and liking and is a subjective top .
No one was hurt at the audition !

Just a small observation to Dans post.
Assemblage DAC-1 D/A is a modified unit with CREE rectifiers and discrete Burson opamps.

Tibi

Yes heavily moded that DAC Assemblage with pure silver inside for connections to RCA , also was tested TDA 1541 NOS and do not impress me (good DAC but a little out of my taste ) .
Also tested : Nakamichi DAC 101 TDA1541 PP in differential mode with upsampling from Pioneer chip !
Sounds very very good , but as this is something vintage and very rare do not posted impressions about .
Also was some 2A3 class A tube amplifier and EL509-02 PP class AB1 and one SRS551 spud tube amplifier for listening .
Everyone was impressed by vicol audio Shiga CD transport as this was by far the most high-end transport / best sounding transport listened by the people that participate on that listening session .
Also I was stunned by the quality of this Transport (again thank to the people that discovered this transport : Peter Daniel and Mr. Shigaraki ) .

skylab, danzup (what a detailed post , Tibi, thank you..

as i could not solder surface mount parts, i don't mind WM8804 - ESS9023 pcb.. but i will consider CS4398 and AKM4398..

years ago i had an Assemblage dac as Sonic Frontiers Transdac (unmodified).. it was very good for the price but a bit boring for my taste and equipment (lm3875 gainclone, dh-labs bl1, proac tablette reference)..

i think sharing experiments and opinions about dac for shigaclone, will be very helpful for builders..
thanks..

Hi Tibi,

Can you estimate the working voltage needed for C43? My guess is that it is pretty low. I have a left over BlackGate PK 220 uF which might work well there in my build, but it is only rated at 4 Volts.

Thanks in advance.

C43 will work at 5V and recommended operating voltage must be 6V.

Tibi

Ill put, also here, some of my email comments.

C27 must be 10uF and yes this have major sound impact.
C21 is in fact 100nF on the original board. We will change this as well.
C43 must be around 220uF and will have sonic impact. A high quality one is a must - go for tantalum, polymer, Rubycon ZA.
C48 and C51 are decoupling caps and are related to layout. A tantal 10uF will do a better job than original 100uF.
We have found also that C18 is 47nF on the original.

Best regards,
Tibi
Have you done many tests with C43 Tibi? I understand this is the same as C916 in the old Shigaclone, right? I did quite a lot of testing in this position last year, and to me, values around 47uF worked best here. Less than 47uF generally meant thinner/drier bass (but my Shiga would work happily even with no capacitor at all). When going 100uF and above, I felt the sound was becoming muddy, with poorly controlled bass. I wrote about it here:
Finally, an affordable CD Transport: the Shigaclone story
and here:
Finally, an affordable CD Transport: the Shigaclone story (I tested more caps since, but none of them are worth mentioning, except BG Nx 47uF/6.3V which I now consider the best choice here, and also "no cap" is probably not really as good as I had initially thought).

I can certainly recommend Peter's NOS DAC, especially if you apply the latest mods he published. I am yet to come across a DAC that would sound more natural and dynamic.
