It is certainly our aim to visit again - lovely countryside there. Combining it with 'proper' hifi makes it even more appealing.
    No worries. Just drop me a message.

    Hybrid design with super linear valve driver stage and MOSFET output stage. 90W rms into 8 ohms, will drive any speaker including maggies.

    1000 per pair.
    Have they gone back up to 90W?

    Life is too short to worry about the opinion of others.

    been playing with some firebottle kin in recent days

    used for a number of weeks with velleman valve pre which is a very modest pre but not bad at all . does not have the massive holographic soundstage of the modwright but then it cost about 72 times less . big bouncy muscular sounding , every big as good as the departed supernait 2 but that had better holographics . does not get too hot but those little valves can get knocked and lost one 2 days ago getting it back in the rack . fortunately thanks to a very efficient valve company billinton export valves i was up at running in less than 24 hours . impressive . this pre power was used with the very big sounding impulse ta`us

    then for a few days used with the tannoy eaton legacy , again big sound and extremely transparent with FM radio , this transparency gave rise to a very very slight hardness at times but very enjoyable . this was using a bel canto pre 3 ss pre amp
    so the msb [ costing about 14 times as much as the FB ] was smoother and better in holographics . that said we have previously tried the FB with the velleman with the eatons and that was very good so a better match i think than the ss pre

    one thing i noticed was that sometimes there was a slight pop when turning off one of the amps when used with eaton [ not the other ]

    i noticed in the instructions that it says the input is dirctly coupled so DC on the input should be avoided . i don`t quite know what this means and thinking of trying another pre amp which says

    "DC filament power helps to create an amplifier with low noise and exceptional sonic qualities. " this amp is based on a herron pre amp design i think

    and wondering if that means the amps are incompatible , perhaps someone technical can enlighten .

    now thanks to our very own jerry [ a big thanks ] i am using the FB with a schiit saga valve passive and that is smoother top end than the velleman and for the money is a cracker
