Hybrid Headphone Amp

The SMSL T1 combines two discrete, independent components into one unit: a DAC on the bottom and a hybrid tube amp on the top. Along with USB PCM support for up to 32 bit/384 kHz, it provides DSD playback support up to 22.6 MHz. The front panel features a headphone output and a large volume control that rotates with smooth, satisfying motion, while the back panel houses a huge variety of inputs and outputs. Along with coaxial, optical, USB, and RCA inputs, you’ll find a DAC out (RCA) and a pre-out for use from your amp to your speakers. One Headfonia reviewer says, "A low price, good sound quality, versatility, a rollable tube. It's really hard to go wrong with this one."

Most (if not all) stock tubes have some hiss, according to my readings and my experience (a friend of mine also bough a DV, and his had it too). My stock driver tube lost almost every hiss just by burn in, I read somewhere on the internet a easy way to do so: with the amp cooled down, unplug everything and wait for a few minutes remove power tube plug power and nothing else (no RCA input, no headphones, just power) turn on the amp let the driver tube burn for some hours (some people leave their DV on for days like that, I turned it on every 8h or so and let it cool for the rest of the day because don't wanna risk starting a fire on a empty office). turn off the amp unplug power and wait for a few minutes insert power tube plug everything back turn on wait for a minute or so, and try to listen if there's any hiss (mine went ALMOST silent after a week of 6-8h daily burn in) However, DV stock hiss it's not terrible, just barely noticeable on the HD6XX/HD650 and only with no background sound at all. And it's just a low frequency tone that doesn't bothers me nearly as much as those white-ish noise hisses that some cheap solid state amps have (or try to avoid with, again, cheap cutoff circuits that sometimes won't trigger and you can easily tell whether it's on or off... super annoying). As you can see, I'm pretty sensitive to background hiss as well, and I can tell you the DV hiss isn't too annoying for me. And it noticeable improved after burning in the driver tube, so no big deal.
