Although the model names have not changed, many new AVA products have received significant upgrades in recent months.
Both the Fet Valve CF and Transcendence 10 vacuum tube preampifiers have received new mother boards with improved split ground plane mother boards and detailed circuit improvements. They now sound even better and are quieter than ever.
The Fet Valve amplifiers have been redesigned from the ground up with new audio boards, new back plane decoupling boards, new raw power supply boards, new small signal power supply boards, improved regulated power supply references, and complete new wiring layouts. They are quiet, amazingly musical, and robust and fault tolerant. 300+ watts per channel for the 600R and 225 watts per channel for the 400R.
None of our products are old or have dated designs, we always keep with the leading edge of audio technology. Only the prices have stayed constant, not our engineering work.
