Nice review!

Funny, because this amp always sounded very bright with my headphones, something I like with some (but not all) of my headphones. Just to point out, it isn't really a hybrid amp. It shouldn't matter at all, but I know some people will fuss over details like that so it's best to point it out.

How do you compare nobsound with the FX-Audio DAC-X6?

great review man!!!

How does the sound compare to the NS-01E​?  They are both about the same cost on Amazon.  Why get the NS-01E over this one (listed as a "newer" model).

@thanderbird thanks
@erich6 using the default tubes they sound quite similar and the main difference would be the footprint. The advantage of the NS-08E is that you can easily change the tubes where with the NS-01E you have to disassemble the whole thing, then remove the bottom plate to take the tube out.

Lol, nobsound.  Think anyone has told them what knob is slang for in the UK?

@TeamHiFiMAN yeah it's not the most flattering brand name but I do think it's memorable :)  It is, for whatever reason the company's English naming scheme. I really don't know why they didn't just use the same Chinese name "XuanZu", perhaps they (rightly) assumed that most English speakers would not know how to pronounce it correctly.

How do you like it with T5p 2nd gen?

@gnidrolog it sounds fantastic with the T5p even though it's a relaxed headphone to begin with. It seems to add a bit more energy to the treble.

@crabdog Thanks for the reply.  Looks like NS-08E might be better to try out tube amps then.  I don't need the smaller form factor and easier tube rolling will be better.

Nice review.  Question.  Any burn-in needed?  Also, how long do you wait for it to warm up before listening?
crabdog

@LazyListener burn-in isn't really needed but I gave it about 10 hours initially. Before listening warm up at least 15-20 seconds to avoid a pop in your headphones then just start using it. IMO it sounds a bit better after its been on10 or so minutes.

Would this power the sennheiser hd 650?

Have you rolled any tubes with it? If so, which and how did the sound change?

@Marshall Mather I'm sure they could power the hd 650
 
@erich6 I haven't tried any other tubes and probably won't at this stage
