Van Alstine Ultra EC Preamplifier Preamplifiers

Van Alstine Ultra EC Preamplifier Preamplifiers 


We started with our basic patented design ideas that have worked so well, and provided even better power supply isolation between tube and mos-fet section with a much higher capability MOSFET buffer/driver circuit, all running Class A, and came out with simply astonishing results; the new Ultra EC preamplifier.

The Ultra EC preamp tells us that simpler is best if you can make it work to perfection, and we have. Our famous patented Fet Valve transimpedance gain cell just loves the high current drive of the 6N1P line tube and the much higher current gain of our power MOSFET design in the loop isolator circuit. The circuit simply comes alive with pure musicality, dynamic range, transient attacks, and range extension we had not thought possible.

Not stopping there, we designed a new headphone driver circuit to match the performance of the line stage. Now you don’t even need a power amp or speakers to hear music as never before, just high quality headphones.
