I have owned many different tube amps along the way
including those from Cary, VTL, Welborne Labs, and Conrad Johnson among others. What attracted me to 3-Dimension audio was the opportunity to own
no-compromise custom amplifiers designed to extract the absolute best
performance from MY system. After discussing my application with Alex, I decided on a combination of 300B SETs for the midrange and upper frequencies and 300B push-pull triodes for the bass – for me, the best of both worlds. I really appreciated being able to speak directly with the designer-builder and REALLY liked bypassing the usual outrageous mark-ups and mumbo-jumbo that used to drive me crazy - when Alex builds you an amp you can see and hear that you are getting exactly what you paid for!

I have owned the 300B "simple" for about a year, with
Sophia Mesh Plate 300B's, NOS Mullard GZ34 rectifier tubes, silver wire
throughout, Black Gate Capacitors, transformers especially selected for
my 16ohm Ocellia Tilia loudspeakers, and separate power supply.
It is impossible to imagine owning anything else, even though I can
afford it. I asked for the musicality of tubes with the bandwidth of
transistors, and I got it! I am grateful for the amp, and for the time spent
listening to music without having to even consider thinking about being
critical. After 30 years as an audiophile, it is a great relief to just enjoy music!
Thank you,

Did I enjoy the sound when I first time turn on Alex’s amplifier on? Yes! Was I surprised that my audio system finally sounds like it supposed to? No! Even if I would not have a chance to audition Alex’s masterpieces before I ask him to make amp for me, I would be sure in the final result. We started with analyzing of all components of my original system and then decided on what amplifier design shall work best. Do they ask you about your audio components when you shop around? Not often. Should they? Even basic knowledge in circuit operation tells you that you have to consider all part of a circuit as a whole. During the time my amp was built I asked all possible questions and we discussed all issues I was worried about. I new that I am going to get what I want and not just another “black box” with glowing tube on the top and with price tag on the bottom.
