I am running the Almarro A318B in my current setup, and having had a ton of other amps (SET, SS, Tube PP), this one really sings and really gets out of the way of the music as much or more than the others! While it was decent out of the box and certainly very usable, I felt that I got the best out of it by having it modded. I took the volume control and input selector out of the signal loop, and basically made it a standalone amp. I also replaced the stock caps with Jupiter Copper Foil caps. In my opinion, it now sounds at least 2x better than its price suggests. Couple that with power tubes that substantially cheaper than their other SET counterparts like the 300b, 845, etc. tubes, and you have a solid winner that you will be happy with for a long time.
