I've seen it on websites, but have no firsthand experience. It's a really nice looking amp, especially in black and silver. Good Chi-fi is as good as any, and these guys appear to be in a higher quality bracket than the the typical $300-400 Chinese integrated amps. I'm curious myself about this one....
I looked at the guts of this thing on a website, and I like it. I'm a QC specialist in electronics by trade, this one ticks all my boxes. Quite a bit of open space means they thought about how to make it efficient, small simple circuit boards where needed, open scaffold soldering, neat presentation. I'm not easily impressed, but this looks like a quality piece. I think you can feel safe about what you are getting. Whether it fits you as an individual? Only you can answer that, but only if you give it a chance.
This thread is a few months old, but thought I'd chime in anyway in case there are still interested parties. I picked up an R8 on Amazon recently and I'm thrilled! My experience with tube amps includes several Separo models, (Pacific Creek) as well as a Cayin AT88. Prior to receiving the R8 I've been running a Vincent SV-237 driving a set of Apogee Centaur hybrids.
Once the R8 burned in sufficiently, (about 8 hrs play time) it opened up very nicely. The image and sound stage are fantastic, and the R8 seems to play above it's power specs having significant punch and dynamics for a 45wpc tube amp. I tried it with a set of Aperion Verus Grand II towers and although they also sound really good, I'm hooked on the imaging provided by the Apogee speakers.
I'm totally satisfied. At $1400 shipped, I feel like I got a stellar value. So much so, that I'm contemplating flipping my Vincent!
Do you know if the amp can be used as just a power amp?


As stated above, there is a preamp in, so separate pre should work fine. Also, I've been so pleased with the sound quality I've not given tube rolling a thought....yet.
One other distinct attribute that needs to be elaborated on just a bit: Punch. I eluded to the fact that this amp seems to punch above its rated specs in my initial post, and I'll add to this by saying the amp is a bit more forward in it's presentation than other tube amps that I've owned. I like concussive dynamics in my tunes, and the lack of this feature in previous tube amps is exactly what got me into hybrid amps, the Vincent SV-237 being the best I've heard. (Within my budget anyway) The R8 is totally satisfying in terms of forward presentation and punch...well above my expectations.
Have I mentioned that I like my R8?![]()
