I've been using this G73-R tube from Vietnam with my Meze 109 Pro headphones, which are super sensitive, and there's quite a bit of background hiss. But when I switch out the tube, the noise goes away. Seems like it's just this particular tube that's the issue. And also, with my 1266...

I'm trying to figure out if the Riviera AIC-10 amplifier has any specific input level limitations, as I can't find detailed specifications on this. Does anyone know the maximum input levels for the AIC-10 to avoid clipping?

Has anyone compared the Brimar 12AU7 with the G73r? I’m really interested in any sound differences you've noticed. I currently have a Telefunken G73-r Red Label and a Mullard M8136 Shark teeth. The G73-r is excellent overall—very transparent and quick—but the vocals/midrange feel a bit dry. My...

I've switched up some power cables, changed the interconnects from XLR to RCA, and even tried different headphone cables. These changes really did help with the sound. But now, I've run into another issue – the screws on the lid of my AIC-10 just won’t tighten up properly.

Yes, would you say those filters make a big difference, especially for the mids and vocals? Just trying to figure out if they're worth the $225. What's your take on that?

I'm using a Mullard M8136 right now, but the midrange, especially with vocals, still isn't hitting the mark for me – they sound very recessed, almost nasal. This is with my 1266TC on the standard cables. I'm thinking about trying out the Tara Labs Omega Live or JPS headphone cables. Has anyone...

Has anyone here tried the Abyss 1266 Phi TC FilterSet? How does it sound?

Awesome, I also switched from the Holo Bliss KTE to the AIC-10, and in addition to the G73-R, I've picked up a Mullard M8136.

It's for headphones. Specifically, it's the AIC-10, and I'll be using it with the Abyss 1266.

Just bought Dave, now I'm waiting on the amp to arrive

I just got a Mullard M8136 tube and I'm waiting for a G73-R to come in. Can you tell me how they're different in terms of sound?

Thanks for recommending the Weiss DAC – I’ll definitely give it a try! Has anyone had experience pairing the AIC-10 with the Holo May KTE? I'm curious to hear any thoughts or experiences with this combination

It appears that the majority recommend R-2R DACs as a potentially better pairing for my setup. I'll definitely explore these options further. Your input is very much appreciated!

Hi everyone, I've recently ordered an AIC-10 amplifier from a distributor here in Hong Kong and am now in the process of selecting a DAC (within a budget of $10,000 USD). I've tried a few combinations but found the sound to be a bit too forceful and not as delicate as I'd prefer (English isn't...

Is it possible to adjust the AIC-10 amplifier from 220V to 110V on my own? Also, I've tried contacting the manufacturer about this but haven't received a response yet.
