Linear Tube Audio- Micro Z-OTL Preamplifier - Upgrades Mk2 to MK-3

Hello to all,I would like to clear the Air  , when I found out that there was  a major upgrade to the MK-3 Version  preamp being I just ordered this the end of December I was a bit upset..the owner Mark called me personally and explained the whole layout which is a Huge upgrade and these new Ceramic circuit boards are 8x as much $$ monies as the previous ones , dynamic swings will be night and day better with a 80k uf capacitor upgrade giving you well over 100k Uf for dynamic swings, and soundstage and greater image depth.

being 67 years old with partial disabilities and on a limited income I over reacted , the pricing is pretty fair when you realize they have to gut  the whole interior  and all the New ceramic boards location changes , far more allotted space for all this capacitance upgrades , with a newer better soft start  to go even easier on you $$ costly Vintage tubes. 

  • the Rays tube upgrade is excellent BTW. Mark literally called me Personally  for I was at the tail end of the Mk2 order.  He  is old school like myself and his integrity is first and foremost . I totally didnot understand the complexities  of the Massive upgrade. There are over 10 upgrades ahead of me. The week after next I am sending my MK-2 Micro Z- OTL in for the transformation , I will use my trusty  Isotek Run in cd for the breakin  24 -7 for a week .  I now own 3 precision pieces of electronics from them. These guys are one of only a handful who put their reputation first and foremost.  I will give you a honest  review of my upgrade findings .Enjoy your music 🎶 Fellow Audiophiles.

I totally agree LTA like dealing with Nelson Pass in the past they take pride in their work and go the extra mile to try to please their customers l Agree the 30% off is very fair and they pay for shipping and insurances .

I am very much looking forwards to hearing the upgrades ,mainly now one big Ceramic board and a small ceramic sister board there are a bunch of upgrades .

pits already a great sounding preamplifier ,I got the Lundahl input transformer upgrade , the Rays 12AU7 is a very good tube nice detailed and rich sounding 

and a 1 year warranty which is great,for the smaller 12au7  I invested in NOS Telefunken Medical grade red tip tubes which are a great complement adds even more detail. And I upgraded all 3 fuses  not too much $$ but adds more transparency Hifi tuning 20 mm. supreme Silver gold fuses .the Isoacoustics Bronze footers are a very good upgrade for feet at under $200.
