Description

Hello,

I built this room over the last 4 months with my 70 year old father. It was really great bonding time. I will cherish the time spent doing this forever.  We are not carpenters and prior to this not even weekend warriors, nonetheless, we went for it.  My room material choices and "room within a room" were inspired from the studio builders on the Gearslutz Pro Audio Community.  

This is a partial room within a room. The walls are double wall construction, each 2" x 4" wall frame is insulated with Roxul Safe and Sound Insulation, there is a 6" air gap between the frames. The ceiling is not floating. I did not want to loose the height. The outer layers of the walls are 3/4" pine + 1/2" pine + 3/4" pine shiplap.  The ceiling is 3/4" pine + 1/2" pine + 3/4" southern heart pine planks.   

I am very settled with my equipment finally. However, I do plan to explore and add digital this year.

    • Doshi Audio Monoblock V3.0

    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!!!!

    • Schroder Tonearms The Reference SQ in Snakewood
    The Schroder is very natural sounding tonearm when dialed in.  Admittedly, it is a challenging set up to get the most out of it.  For a few reasons, it is capable of so much and the set up variables interact to a greater degree with one another than the other arms I have experienced. This is a blessing in the end, but it does makes set up take a few months with a new cartridge.
