  • for those of you with high efficiency speakers...the ampsandsound Mogwai

    Been trying out the ampsandsound Mogwai amp for the past couple of weeks. Single ended running a single 6550 per side for about 4 watts max into an 8 ohm speaker. Sold mostly as a headphone amp, but with speaker binding posts too. Not compatible with a passive linestage (not enough gain through the speaker terminals) so I've been using a Burson Conductor Virtuoso instead of my DIY passive. This is is proving to be a really sweet amp with my Tektons. I'll be writing it up in Positive Feedback at some point in the future.

        No shame in that, as my now late friend said, when he started selling Porsches instead of Ferraris. For people who aren't obsessed with this stuff, that's real money.

          don't confuse money with obsession. We all spend more than we should on this stuff!

            That's an interesting choice to use a pentode output tube for a SE amplifier. Any particular reason? Are they running the 6550 as a triode?

              Yes, but I don't think it is that uncommon. My Antique sound Labs amp runs a KT88 single ended for 5 watts, though it offers a triode/pentode switch and puts out 15 watts in pentode mode (which I feel sounds better with my primary speakers). The Almarro A205A is a single ended EL84 amp that sounds wonderful with about 3 or 4 watts output.

              Big benefit of these is cost. You don't have to spend crazy priced for exotic or vintage triode tubes. The last really nice pair of matched KT88s I bought were about $70/pair.
