The AMX tube amp is best used with high sensitivity speakers like the Fostex FE167E (94db).
EL34 AMX costs P12+++ when available.
The Fostex FE167E Bookshelf (BS60) costs P15,000. The floorstander version (Brines 1.1) P20,+++. A 3rd version is the Fostex Mini Voigt MV167 floorstander. See wiredstate.com for these offerings under wiredstate projects forum.
I haven't heard the 320 nor the AMX (not properly, because it was driving an 86db speaker when I heard it).
Currently I am using a Rotel RA931 Mk II P15,+++ and a Fostex BS60 bookshelf. I love the resolution, mids are great, but shy on sub bass. I am still hunting for a good sub.
www.pbase.com/bs60The 931 is often pitted against the 320 BEE in terms of price and performance.
For P15,000 (P11k DIY) , look into
www.wiredstate.com TB 2A3 tube amp project. I heard this with the Brines Fostex 1.1. Nice combo.
Tube vs SS, pansin ko, mas holographic ang tube and bass is more defined. But difference is only noticeable when rapidly switching between the two for comparison. After playing the SS you begin to forget what you are missing. Well I do anyway.
I would like to hear the AMX with the Fostex and see how it fares against the Wiredstate.com TB 2A3.
