Thanks Mike, I know Ian's question was aimed at the electronics but I just wanted to put things into prospective. OK Tron and electronics wise:
Exhibiting and being chosen to provide the electronics for Avantgarde Acoustic's room at the Frankfurt show for 5 years (1998 - 2002)
Exhibiting and being chosen to provide the electronics for
Cessaro and TW Acustic Room at the Munich High end show for 3 years (2012 - 2014)
Featuring in the top
Korean HiFi magazine and selling a 300B amplifier to the owner.
Having a lovely article written by Roland Kraft, Germanys top reviewer (Image HiFi) and often referred to as "Mr Tube" - article
here. The article was translated by Holger Fromme, the owner of Avantgarde Acoustic.
There are many others but I'll stick to these for brevity.
Equipment wise
Without doubt the one piece, well two pieces actually, of equipment which are my proudest achievements are both at completely opposite ends of the market. The
Convergence phono stage starting at £1000 is top as it's the cheapest product I make, therefore it had to meet much more stringent criteria. It had to be extremely good sound wise. It had to be easy to build. It had to be extremely low noise for a valve/tube phono stage and it had to be affordable, so many could experience some of the high end sound for significantly less money. It had to be built to extremely high standards, as well as to offer an upgrade path to make it sound even better. It was very challenging to meet all of this criteria, especially for the price.
The other is the
Nemesis Preamplifier and the
Nemesis Phono stage. Both these were built as cost no object designs and both are 2 box amplifiers. Having a free rein and a no compromise strategy was very liberating, as was the money exiting my wallet to build such devices. The phono stage for example has a power supply which weighs all up 35kgs. The other case which houses the audio circuit weighs 25kgs, so a total of 60Kgs (132 lbs or about 9.5 stone) all for just an MM phono stage! There is a lot of iron and copper in both chassis's, as in super high quality transformers. These also took the best part of 6 months to build...
