Gear: Berlin R Mk-II + Audio Tekne Tube Integrated



Hi, David:


Yesterday I hosted a small gathering of local audiophiles and, last night, I received the comment, below, from one of the guys who attended:


"Thou art the host with the most; the mostest, baddest, outrageousest audio system I done ever laid ears on.
And that ain’t the half of it....

Thank you for the opportunity to witness the splendor. I’m honored to have been able to spend an afternoon in audio bliss; not once ever hearing ANY deficiency AND hearing the most complete absence of “electronica” in my 60 year pursuit of live music at home. Everything was RIGHT and righteous.

January 23, 2020, a day that shall live in glory, stands as the high-water mark of my 6-decade quest for the truth, the audio truth, and nothing but the audio truth.”  Wow!!


Last week I finally broke down (after 16 years) and re-tubed my Audio Tekne amp per Imai-san’s instructions.  Namely, I removed the Sophia mesh plate 300B’s and 274A’s and replaced them with high-quality 300B’s and NOS Sylvania 5Z3’s (2 rectifier tubes).  I also replaced the preamp tubes with NOS Telefunken 6463’s (2) and 5687’s (2). Basically, I returned the amp to the way Audio Tekne intended the amp to perform.


The improvement in the sound of the amp is beyond my ability to describe, but the comments, above, are a hint.  The guy who wrote those words, and about four others who attended, are now scouring the web for Audio Tekne equipment and Viking speakers.


If you are looking for a reason why I am hesitant to move forward with L’Instrument, you have to look no further than the absolutely unbelievable sound of my current system.  The general comment yesterday was “don’t change a thing!”


The Berlin’s, driven by 8-watts of Audio Tekne power, produce the most dynamic, dramatic, and realistic sound I, and others, have ever heard.  And, we are talking about seasoned, well-healed, audiophiles who can pretty much afford what it takes to achieve sonic nirvana.  


If anyone in New England is interested in listening to Viking speakers, one session at chez Bob will convince anyone to move forward.  And, the extremely high w.a.f. is icing on the cake.


Absolutely unbelievable!
