Another Alan Kimmell Giant Killer Design
Here is a link to a page in the ModWright site. This company has introduced its first built from scratch product, a tube line stage preamplifier. Alan helped out with the gain stage; the company previously comitted to use his design philosophy and went straight to the horse's mouth.
Alan's Mu Stage design ideas have raised tube amplification to a new level. The use of complex circuits and many super expensive components are no longer necessary to overcome design shortcomings, so the price of high end plunges to a new low. Note in the reviews:
The SWL 9.0SE ($2,200) earned the Blue Note best of 2005 Award, alongside the Wavac PR-T1 Line preamplifier ($30,000) and the Lamm Industries L2 Reference Preamplifer ($14,790), in the preamp category.
Also note that several reviewers issued the ultimate compliment; they purchased the review units!

My $995 Grommes PHI-26 amp sounds like ten times the price, at least. Highly recommended. Its component and build quality levels are equal to the design quality, superb, so you can't lose.
I wonder if Nelson Pass has read Alan's article. Alan covers using MOS-FET's instead of pentodes; his hybrid design (triode voltage gain stage to MOS-FET current amplification stage, see article http://www7.taosnet.com/f10/mustage.html) looks like a sensational idea.
