Hi Ron.
I have had several Mastersound amps and they are very good. I have not heard this amp though. But for their asking price Mastersound sound excellent. They are stable and reliable as well.
But 4 845 tubes will for sure heat the room they are in, but I suspect that you have a nice sized room so it should not be a problem.

Dear JP, Thank you for responding.
Have you ever compared your Mastersound amp to an Absolare amp?
Hi again.
The Absolare is of course better, as it should be. Absolare makes 85 watts monoblocks as well, if that is enough power for your system. But they are costly . I have heard Kondo Kagura with my speakers, but the Absolare integrated is not far behind these super costly amplifiers in terms of sound quality.
I have also tried the Mastersound E 845 integrated. Although not up there with my Absolare it is not night/ day difference between these two. So Mastersound makes very good amps, there is no doubt. More refinement is of course possible, but then you must be willing to spend much more. The best Mastersound amp might be their Dueundici, a 11 watt pure set integrated wonderamp. Of course not for your system .

I have a small single driver speaker system that the Dueundici might be perfect for...can you tell me more about what you have heard from it? I can get one pretty cheap...
For sure in Class A2 and not all in Class A1 (where around 50 watts is about the limit.) Unless these are monoblocks with 4 per channel but it looks like a stereo amp as there are what appears to be two output transformers. What little measurements I have seen from Mastersound suggests that their output iron is too small. This was also true for the early Ayon amps, which were made by Mastersound, as we have compared an early Ayon 32B amp to a KR VA350i and it was really wanting in the bass clarity and punch department. My Crossfire was a whole other animal with huge output iron for a 30 watt amp. The weight of this Mastersound is not enough, IMO, to have serious enough iron for the amount of DC current that has to flow through the output iron to those big 845s. An amp like that should probably have at least 15-20kg output trannies with a total amp weight nearing 70-80kg. NAT monos would be in the 40+Kg each range for similar power. Kronzilla monos are nearly 50kg each. AC monos are 100kg each just by way of comparison.

Dear Brad, I believe the PF100 is a mono amp -- four 845s per channel. Each mono amp is 110 pounds, which seems about right to me including big iron transformers. My double-decker 750s weigh in at 120 pounds each.
KR Audio 845s in this PF100 amp might improve its sound quality?
So does Aries Cerat make something which is Class A and not push-pull and which outputs 100 watts or more into 6 ohms?
JP, did you listen to the Kondo Kagura with standard tubes, cables and fuses? I am wondering because the Kagura should be better than the Absolare in many important aspects.
Or what I did not hear. The Dueundici is totally transparent, a small wonder of an amp. Buy it!
