I really like OPA627Au, despite the fact that it measures less well. Warmth and layers. 

Guess that's a bit like home audio amps with little or no feeback which are horrible at the bench yet can be wonderful sounding.

Finally I test the DIY broad for TO-99 Single Channel OP amp, made for Valoq.
 
Test for unbalance only.
 
Comparing OPA627BM and OPA627AU (DIY, with Double-sided Broad), sound better, however, just a slight improvement on smoother highs,vocal also a bit of more focus.....all in all, not much differents.
 
Maybe not enough supply voltage to tell the difference?? Consider BM (DIY cost) is more than double, OP627AU is already a very good choice.
 
Agree on the Measurement vs listening audition.....I also Try LME49710HA (single) with broad, LME 49990 (single) with broad...they all measure very good, sound very clear, details......but also...... boring.
 
OPA128SM sounds very, very good to my ears. Sadly it on the warm side, plus the already on a "warm" sounding on Valoq....very good on vocal and instrument type of music, but less dynamic on others.
 
I'm use to "hate" OPA 6XX" series in my diy project.  Sounds very wide but with too much "unreal colors" on Mids and Highs...but..
 
Consider this is only one mod (OP amp change) in Valoq (also a selling point), OPA627AU/AM/BM is my choice and it just help to balance it with Valoq's warm sounding, make almost all music sounds nice.

Selling my basic model for local pick up in Singapore.

http://www.head-fi.org/t/802594/venturecraft-valoq-basic-model#post_12446930

Looking to buy a factory fitted OPA627SM unit.

Too busy to box and ship out, hence the preference for local collection.

I caved an ordered the opa627au, wasn't cheap but had to try it. They arrived today, the fit inside is just enough, the opamp are certainly touching. Too soon to tell of the changes. I wish the 627sm was cheaper so I could try, I am going to try my luck and see if they are willing to send me a loaner unit. From doing my research the opa627xx family require proper design to perform their best but honestly I don't know.
 
I for one love the operation and UI of valoq. it is not as good as apple but than again what is, for my purpose it does the job, it is fast and I do enjoy the scroll wheel. If anything I would have pereferred that FF was carried when the operation button is pressed once, I just dislike double clicking the scroll wheel.

I have been enjoying my Valoq with the opa627au for the past few weeks. This week I'm trying out my new Kumitate Trio which is rather crisp sounding, and I have just swapped back for the Muses02 for a (theoretically) nicer match.

FYI, for US fans, salehifi.com (VC's shop in HK) just posted various amp alternatives and Volaq configs for sale on their site.

 

[audionewbi]

salehifi is where I bought my staff after having zero luck with VC Japan. I highly recommend their balance trrs cables. I am still burnin the opamp, I will report back late.r

Good to know. Actually I was thinking of buying one but later I understood that I need silver and not copper and have ordered the Silver Dragon trrs from moon-audio.

No, and this was why VC reworked it so the OpAmps go to the underside of the board instead for the Valoq.

Thanks for the info, where is the best place to get the compatible valoq opamps from ?
 
Any recommendations - especially for the OPA627SM

Mouser or DigiKey for the chips, then ebay for the boards (I posted them here in the past.)  However, SaleHiFi.com, VC front end in HK, now carries official OPA627SM version of the Valoq.

Thanks for the info - one last thing do you have a link to a board that would be compatible? cheers

This one might work, but you won't be able to close the back.
