The Doshi V3.0 is the amp that lured me out of a decade of SET amps. Most of my SET decade was spent with an Audio Note Jinro.
The Doshi 3.0 amps with KT150 tubes are very special, IMO. While looking for speakers and electronics for my new larger listening room, I listened to these amps with Wilson, Magico, Quads 2912, Harbeth 40.2. Each speaker sounded very different from one another. The Doshi amps did their job showcasing each speakers character.
The Magico and Doshi combo was linear from top to bottom, with super tight bass. I did not think a tube amp was capable of such tight linear bass.
The Wilson Alexx and Doshi combo, is exceptional, the bass is clean, extended and very natural. The midrange is textural and the highs are wonderful. This combo is super dynamic as well and portrays scale like few other speakers. The Alexx/Doshi combo is the most balanced speaker combination I have ever heard from top to bottom, it is darn near perfect. It checks all the audiophile boxes. However, I was not shopping for speakers at the Alexx's price point. But that combo sealed the deal for me, related to Doshi Electronics.
The Doshi amps with the Harbeth 40.2 is also exceptional. It does not check every box like the Alexx/Doshi, but this combo connects with my heart. I have a really natural midrange, male and female vocals are to die for. My treble performance is sweet yet extended. My bass performance is not perfect and is where the 40.2 strays from neutral. My bass is a touch fat compared to the Magico and the Wilson speakers.
I am not trying to review speakers, I am trying convey that the Doshi 3.0 amp is capable of warmth, neutrality, dynamics, scale, control, energy and nuance - just pure music. The Doshi 3.0 is a “straight wire with gain”. They are as good as it gets to my ears!!!!

Thank you for the compliment about my room and gear. I viewed your room as well, I am a fan of your choices.
The Doshi Jhor amps with EL34 tubes are very nice, great midrange as you would expect in an EL34 tube amp. Nice bass and treble, though it does not have ultimate bass control or frequency extension. The EL34 tube has character that is always present whereas the KT150 tube does not editorialize. If one does not want editorializing than the KT150 tube is superior.
I think the Doshi 3.0 amps with KT150 tubes amp are exceptional and capable of ultimate tonality, control and transparency. They are more refined and sonically complete then the best SET amps that I have owned. I know that seems impossible, but it is true.
