Title: MiniWatt Amplifiers
Post by: MasterBlaster on August 20, 2011, 04:15:50 PM
Has anyone ever tried tube amps made by MiniWatt?
They seem to have been getting attention from a number of audio critics including Stereophile, and Tone Audio.
I may pick one up out of curiosity...

I've looked at the N3 many times.  Last time I was interested, research revealed there was some controversy about who could sell the units.  Maybe that has gone away.

Bought this Ming Da amp instead for a few more dollars.

Looks cool!
  What speakers are you going to use with it?  3.5 watts, they better be efficient.

I have no clue.  I do not have much experience with flea watt amps.  I have a Kenwood 18 w.p.c. tube receiver.  It sounds good with the pair of DCM speakers I have.  They hit 97db with 1 watt!! And they sound pretty darn good.
  I would look into some of the vintage Klipsch speakers.  They do well with little power.  I am sure that some other members can recommend some speakers.  I know someone on here was using flea watt amps, but the name escapes me at the moment. (to many prescription narcotics has my brain in a daze) Hey, that may be a great user name..  Braindaze.  :o :o :o

Those huge Altecs OCCD had at the old shop last time I was there would mate up good with a low power tube amp.  My Klipsch KLF-20s sound good with a EL84 tubes amp I have that put out 5-6 watts.

The driver tubes on these amps are hum prone though......something to watch out for if you go with this one.
