My NorCal system is finally singing late 2016...very pleased. Had to progressively convert all my gear from 240v to 110v throughout last year. Then I got the new LDR pre-amp and finally had my Tom Evans Linear A (hybrid SE 2xquad EL84s) fully upgraded to Mk2 specs.

With a dedicated room and the space for it, my Bastanis open baffle speakers are just 
singing. These are the CHRYSTAL versions (violin lacquer applied) of this wonderful high efficiency (110db) speakers. Qualities of horn without the issues! Panels are ply from Finland.

I've always liked the transparency of TVC (Transformer Volume Control e.g. Music First) but missed the drive of a good active and I also wanted a remote! With my more efficient speakers, drive is no longer an issue, and with the LDR I found a affordable remote based option. Transparency, as expected is amazing!

Alan Maher power treatment means the sound is dead quiet with ever so 'real' nuances and tactility of live performance coming through.

Room still needs work, some dampening/diffusing here and there and my grounding needs to be upgraded. Need to experiment speaker placement more - it can sound a touch laid back at the moment.

    • Bastanis Speakers Mandala
    Top of the line CHRYSTAL versions (violin lacquer applied) of this wonderful open baffle, high efficiency (110db) speakers. Qualities of horn without the issues! Panels are ply from Finland!
    • Tom Evans Audio Design Linear A mk2
    Fully upgraded to MK2 status in summer 2016...including new boards and pure copper (not brass plated) speaker binding posts. Even more quiet and thus natural / dynamic than before!

    Linear A is a hybrid, single ended, Class A, ultra-linear stereo amp with 25WPC. Four EL84 tubes per side, in parallel, create a composite tube with characteristics almost identical to the legendary Japanese No.10 tube.
    • Tortuga Audio LDRx
    Remote controlled 'passive' LDR (light dependent resistor) pre-amp that lets everything through uncoloured. Very similar to a TVC sound wish, perhaps a tad more transparent but a tad more finicky when it comes to matching.
    • ModWright LLC Oppo 83SE
    Fully tricked out Oppo 83SE by Modwright including external power supply with rectifier (5R4GY) and tube output stage (6SN7).
    • Alan Maher Designs Various

    Superb - direct sound without any edge. Oyaide plugs, litz cables, Alan Maher power upgrades.

    These platforms help drop my noise floor without the downsides of using power conditioning ie. losing PRAT/being coloured.
