For the past month we have been shipping upgraded models of all our Insight and Fet Valve Ultra power amplifiers. The back labels on the newest versions will say "Insight+" or "Ultra+".
The upgrades are not earthshaking, but are obviously nicer overall musical improvements in all our solid state and hybrid power amps. You will quickly notice better bass definition and impact, a "sweeter" top end, and better transparency overall.
The upgrades are simply the result of more detailed engineering work here always trying to track down and eliminate whatever worse case issues might still exist. They consist of improvements on the audio circuit boards in all cases. It is not a "do it yourself" project.
We can install the upgrades in any existing Insight or Fet Valve Ultra power amplifiers. The upgrade price is $200 plus shipping, including parts and labor. We have kept this upgrade price as low as possible, thus it will not extend the warranty of your amplifier as we do with major upgrades. The upgrade cost is $300 for our three channel amps.
With these upgrades, our three amplifier designs; solid state, hybrid, and pure vacuum tube, are converging in sonic excellence. We think you will like the results.
All three will be on display at the upcoming AKFest the weekend of May 1st. See us in room 200 along with SalkSound.
Please call us at 651-330-9871 for details.
Best regards,
Frank Van Alstine
