I have bought the 100se here for a year now. I chose it after listening to many amplifiers, cheaper and more expensive, with speakers that I knew quite well. It replaced a denon pma1500r. I never missed the absence of controls. It plays exceptionally well at very low volumes, which was very important to me and was the point where almost all the other amplifiers I heard in the store failed (around this price range). Its soundstage is not its strongest point, but it doesn't present a problem. The entire musical spectrum is crystal clear, balanced, and somewhat atmospheric but not overly colored. It has excellent resolution across the entire spectrum, and if I had to find something negative, it would be that it lacks the low-frequency extension of other amplifiers of similar price, but as it goes down, it goes down with detail, authenticity, and never becomes harsh. In my opinion, its price should not make you think that you have to match it with speakers of equivalent value. It can support much higher-end speakers than those suggested by its price. Personally, I drive a set of troels gravesen revelator 4r speakers, upgraded, and I couldn't be more satisfied. Finally, regarding the sound expression, I would like to say that George is exceptional in his work and he helped me a lot, patiently, in the selection. It is indicative that since buying the amplifier, I have trusted the sound expression again for: purchasing a phono stage, purchasing a turntable cartridge twice, purchasing stands for the speakers. And I am sure I will trust it again. Soon, in fact.
