Just finished this pair of amps. OPA549 poweramp with snubbered psu. OPA627/BUF634 preamp incl. linestage, headphoneamp and RIAA amp. Wanted this pre to be versatile, so it can act as a standin on the main system, when modding.
This set of amps will do service in my workingroom, connected to the PC, cd player and a tuner if I can find one that would fit in with the colors😉 Its a sweet sounding couple😎
A few pics follows.

Thanks a lot.
Also thanks a lot to Pavel Macura for the very nice boards that I used in the preamp. Our PMA on this forum🙂

Nice work! Congratulations!!!
Tell more about chassis - is it all made out of aluminium? How is it finished?? I like the brushing effect - did you do it yourself or ...

Wow, guys.... Thanks a lot for the kind words.

The chassis are bought from Taiwan. Easy enough to order on the internet. Here is the link to the mekka🙂

These chassis are all aluminium, brushed and anodized. Jrsun makes a groupbuy on something similar, but not in this small size (approx. 20x25cm or 8x10") and the Champagne color.
That psu is totally quiet, thanks Nuuk.
Overall I will rate the OPA627/BUF634 preamp higher on the HiFi ladder than the common GC/chipamp.

Its Jantzen audiocaps 3,3uF, similar to Audyn.
Nuuk, Hmm, maybe you are right, but these amps can come in handy when I am messin' with my other amp😉 Did you recognize the psu in the preamp? It's taken from your own homepage😎
That psu is totally quiet, thanks Nuuk.
You are right Pavel, these two last boards did come to good use as you see.🙂

Very nice work Steen!
Now I'm out the door for a evening fishing trip 🙂
Can't always listen to music, has to listen to the nature also, no tweaks needed 😉

Damn, Steen.. Smooth is all i have to say, very nice work.
what kind of soundcard do you have btw?
one of theese days i'm gonna make myself something not too unlike this, drawing on my past experiences ac a computer casemodder.
the theeme is back-painted plexi glass for that increadible glossy finish and matching preamp, power amp and computer 😀
keep it up!
