Portaphile MICRO on Headfonia’s Wayback Wednesday

I hadn’t been on Headfonia for a few months and decided to check out what was new on there today and realized  that they featured the Portaphile MICRO on a wayback Wednesday back in May 2017.   It’s crazy to think the MICRO was first reviewed by Headfonia in 2014.   I can’t believe it’s […]

Portaphile NOK “Nude OverKill” Update

Thank you everyone for your patience in allowing me to get the amplifiers designed, built and shipped out within the planned time frame.  I am currently expecting to ship during January 2017.  I am still machining the cases and as I had anticipated early on, that is my bottle neck in producing the NOK.  The […]

First Listen: NOK aka Nude OverKill

Portaphile NOK aka Nude OverKill RCA Inputs

I have been getting so much interest to include RCA inputs on the final NOK that I’ve decided to make it standard on the final version.  The NOK will have both a 1/8″ mini jack for both input and output and RCA input jacks to allow easier connection to the Chord Hugo via RCA’s.   […]

Portaphile NOK “Nude OverKill”

Here’s a teaser pic of the inside of the upcoming NOK.  This test board is still missing the gain switch and Vishay Z-Foil “Naked” resistors in the two step attenuator.  Abosolute resolution is probably the best way I would describe the sound this amplifier is capable of reproducing.   The Z Foils are able to […]

Portaphile NOK aka “Nude Overkill”

I thought it’d be a good time to release a bit more information on the Portaphile NOK.  The Portaphile NOK will be based on the three channel amplifier architecture found on the 627 line of amplifiers.   It will have three OPA627BM followed by six LME49600 buffers, two per channel.  The OPA627BM is the higher performance […]
