Edwards Audio IA1-R Integrated Amplifier

IA2-REdwards Audio IA1-R Mk2 Integrated Amplifier


Essentially this is a Remote controlable version of our Apprentice IA1 but has an improved power supply based around a 200VA custom wound transformer and has DC blocking on its AC input. It has a back lit GREEN LED Acrylic front panel display with a 9mm thick custom machined frame with 40mm dia turned aluminium control knobs which are finished in a black anodised bead blasted finish.


It makes an ideal partner with our SP1 bookshelf loudspeakers and TT1 turntable when plugged directly into the OPTIONAL internal custom designed RIAA MM input board. This makes for a very well balanced and musical system who’s performance belies it’s modest price tag.
