That’s not a problem. Thanks for reposting.


The conventional wisdom would say that the speaker is a poor match for a low powered amplifier. If I needed more power, couldn’t I just add a second 6C33C as an additional stage after the first?

Since I have been pairing the speaker with a SET amp using a 300B driver tube I feel that even without an additional stage it may still be worth experimenting with this amplifier or other low powered amplifiers. I can say that the current amp has no problem outputting way more volume than I need in my room, nor does it account for any noticeable frequency response shifts. The details of a recording while maybe not displayed with the microscopic precision of a great headphone setup are there as well, not obfuscated greatly by inefficiency. I don’t have any way of testing but the speaker is supposed to present a relatively flat 10ohm load. The shortcomings seem to be that the speaker can sound overly polite and distant, and can struggle to keep up with complex musical passages. Peak to peak dynamics don’t begin to replicate real world live acoustic music, though the dynamic shadings of individual instruments help flesh out points of emphasis.

Higher powered solid state amplifiers don’t necessarily correct these problems which I would say are indicative of an incompatibility between amp and loudspeaker. More power also just seems to drain the performance of its subtlety and much of the emotion of whatever is playing. The problem with the setup as is has to do with the underlying musical intent or direction not always being clearly presented. It can be hit or miss even with the same recording played at different times. There are a lot of variables at play and certainly the listener plays the biggest part in the equation. I just feel that as a tool used to place you in that meditative state of being absorbed with a piece of music, it’s a pretty inconsistent device and too incompatible with differing recordings.

I would be interested to hear how the Melquiades amp presents musical content even facing the limitations of the speaker. The limitations I find which I assume are related to an imperfect match between speaker and amp are certainly distracting but they’re not deal breaking for me, at this point.
