Great product.
I bought the Rokctron Mainline to pair it momentarily with a Pod HD Pro in place, before a head Line 6 Spider Valve MKII (only used as a power amp), and then the legendary MESA BOOGIE 2.90 (too inconvenient, expensive and heavy management ). Assuming that it is virtually impossible to match the density of the sound of the MESA (and valves in general), I must say that the Mainline however, can defend really well. It has a very defined sound, precise and warm enough despite being a power amp transistor. Surely accomplices resonance and presence separate settings for 2-channel very responsive and going to act directly on low and high. E 'rather quiet and the cooling fan does not feel practically never. I use it in stereo 75w 8 ohm. It seems well built, I did not find inaccuracies or misalignments, the knobs of the potentiometers seem solid. The only real flaw is seen a tendency to be slightly dark, oriented to give precedence to low harmonics, partial problem with the pre controls can be corrected. Give my needs was definitely a good buy considering the price / weight / quality. It remains to be reliability and durability!

Slapchap is going to fascinate you
Sergi V., 28.11.2016
The only problem I can find is that at the time of assembly, the holes were not completely aligned for the anchorage to the rack, so it was somewhat expensive, for everything else;

Wiring and very easy use, it would not be necessary to look at the manual.

Sound of 10, totally respects the sound of what you want to amplify, and has potentiometers presence and resonance to adjust the brightness and general bass, in case you use any screen that you need or on either of these two qualities.

I'm currently using it in bridged mode with a 212 Boogie Table and I do not need to turn up the volume to much more than 1/4 to hear me both in rehearsals and concerts, so there is leftover power.

Totally recommended.
