Hey guys just stumbled on this thread...have one of these and replaced the op's would one go further? Anyone messed with caps/resistors? Also tube rolling...seems a bit of a pain because of the soldering...surely a mod to get a couple of 8 pin tube holders in there lol

And maybe a better battery pack? That could fit straight in?

Never heard of this op amp, but seems to me that it's Chinese made and a clone of Sparkos SS3602.

a clone of Sparkos SS3602

don't think it's a clone, it actually sound way better (to me) than the Sparkos. check this out

How's hissing?

none that i can hear, but i have good headphones and good DACs. the sound that come out is amazing especially with the T1 4497. the only problem with it is the battery drain after less than two hours! so now i have to replace the battery pak

How's hissing?

i just played hifi files via Tidal with my k20 pro (great sound card)witch i connected to a nx4, then to little dot3 ((with upgraded tubes) and then to my upgraded little bear, connected to Sennheiser HD 650! OMG!!! with the HyperX Cloud Alpha it is even better !

 

[fabien32]

But after 10mins playing, it balanced again

I have a b4 and it balanced after 30 minutes but with all the upgrades it sounds amazing

 

[Grindcore77]

Hey all in the process of modding mine..went the miniature socket route so rolling tubes wont be such a PITA..

Waiting on some more parts to finish up.got some sylvanias in at the moment...

Anyone had a play with the b4x, thinking of having a modding session with it.
