I have always been curious to see the MastersounD PF100 mono-block amplifier in person because it is one of the very few Class A, parallel SET amplifiers achieving 120 watts output (four 845s). MastersounD recently upgraded the PF100 to the new Litz Edition, with improved capacitors and an upgraded transformer.

It is very large in person, and it looks like it is beautifully made!

Thanks for posting Ron. Any thoughts on the sound? MastersounD posted a short clip on Facebook that led me to believe they were getting fairly good sound at the show.

No, unfortunately. I was zipping along at that point, and the system was completely unfamiliar to me.

I was in contact with MastersounD about a year ago at which time they told me about their pending Litz upgrade version, and I was very excited simply to see in person the upgraded version of the amplifier. Visually, I like how massive the thing is, and I like seeing that row of four 845s!

And I like those three massive transformers, for which MastersounD is, I believe, highly regarded.
