Hello there!
I have a ifi ZEN DAC with DT1770's but i need more power (i play electronic drums) and i want to get an extra amp that will drive my 1770's. I'm not into tech stuff, but would you recommend this amp for my current setup?

I mean given they have the Tesla driver this might cut it but I mean it's what? 1W into 50 ohm and your cans are 250 but an efficient 250 so Id say yeah, though considering those are bass canons already a tube might not be ideal or noticeable?

Ok all,  I'm in the market for a DAC for my 789 THX and CTH and need some input from you all as so far you haven't led me astray yet.  So far I have been using my Fostex HP4a as a DAC and I'm not even sure either one of these would be an upgrade but I'm down to two.  the   Massdrop x Airist Audio R-2R DAC or the Grace Design Standard DAC Balanced.     I'm leaning toward the Grace as it's balanced for the 789 and your reviews say the unbalanced out of it are almost as good as the balanced.  But the resistor ladder technology has me thinking it has to be the better sounding DAC.  So talk me into staying with the HP4a  or if you have any better choices I've left out  but It needs to be in the price range of these please.   Any and all feedback welcomed and taken with a grain of salt.  headphones used are HD660's, HE4xx's, and Fidelio's for the most part.

Hi everyone! I'm really interested in this amp but I'm afraid I would toast my Meze 99 Noir using it. 32 ohms and 50 mW maximum input for the meze seems to be way too low to match this amp. Am I right about this? It would be nice if I could purchase this one as it seems to be just what I need before switching to balanced later. If the matching is wrong then I suppose I could go for the O2 (ODAC is the dac i will be using anyways) or the atom but I know i'd be much happier listening through the CTH.

This amp will not harm a low impedance headphone like yours. It should make the bass more weighty and enhanced soundstage. There may be a slight tape-like hiss that is noticeable on low impedance headphones though, due to tube noise.

Thanks for your insight! If the hiss is all I should be worried about then I'm in. :) Edit: finally received the amp and you were correct. Fortunately there's barely any hiss even at complete silence. This amp sure is wonderful and it was well worth its price. It sounds awesome right out of the box, even without burn-in. It's nice to finally have a good setup again and rediscover my music :) Do note that the Meze Noir slipped past customs but the CTH was caught (probably the big box). I live in Hungary and after VAT (27% - highest on the globe i think) and customs charge I came to a total of 252$ which would be 272$ at the time I payed for the product (including shipping). HUF sure have gone down since then. I specifically asked them to base it on the date of purchase but they did not. The meze arrived in 5 days, the cth would have arrived in 6 if not for the extra week in customs. Hats off Drop.

I'll regret this if these go out of stock. The 6H23P-EB tube is amazing in this amp. Detail is off the charts without fatigue at all. Way way way better than the electro harmonix. Bass is a bit overemphasized, but to a tasteful degree. Treble is ever so slightly softened but still present, very easy listen.

I've heard that otl tube amps are good for high impedence headphones, such as 6xx or hd800, but less so far headphones that are low impedence, yet hard to drive, such as Fostex T50rp. Is that also the case for these hybrid amps? My current headphones are Sony XB1000, which are pretty hard to drive for being 32ohm, so I'm curious if this amp would be a good pairing. The main thing I want the amp to do is bring vocals slightly more forward, as they feel somewhat recessed with my current setup. Any advice would be appreciated!

Because hybrid amps use solid state to deliver the power with low output impedance it isn't picky about the headphones you use. Personally I prefer using an equalizer like APO with the peace pluggin to modify the sound signature. Using an equalizer you're in complete control of the modifications. Plus it's free. Using a tube you're kind of just stuck with whatever coloration it adds. It may fix/improve one thing but it can also wreck other things at the same time.
