I just attached Duelund JDM copper foil bypass caps to the tweeter Sonicap and the effect is instant. The center vocal image became pinpoint, 3d, and real. She is right there.

Awesome! What does the current listening set-up for these look like?

This is the burn in setup. Just stacking them on servo subs is very suboptimal until I get the proper woofer stands. Using a 10 watt Pass Sony VFET amp, Benchmark DAC3L (has dual single ended outs for the sub amps and VFET), Raspberry Pi running Volumio.

You know, I have a lot of amps from best measuring on the planet to really good tube amps, but there is something magical about these Zenductor 2 amps when driving the Superminis.

But how do they M-E-A-S-U-U-U-R-R-E… ? ? ?     

Sorry… I’ve just been reading too many (other) forums and comments about such things lately… 😇

Well, speaking from experience. If someone who owns a Benchmark AHB2 swaps it for the Zenductors, they will want to jump off a building for spending $3500 on it and not $200 for a pair of 10 watt amps.

Those are real neato burrito.

Get a USB measurement mic from Dayton Audio and REW software for speaker measurements.

Use the mic calibration file in REW to correct for the mic frequency response.  Typically, the 0 deg calibration file is available for use.

Other mics like the Beyerdynamic MM-1 XLR phantom powered mic has both the 0 deg for quasi-anechoic and 90 deg for room measurement calibration files.

I have a Minidsp UMK1 mic and a stand. Haven’t used it with REW yet. But I am going to play around with it. Was going to play around with Audio Weaver and the NexusDSP also.

See now, this approach just seems far more reasonable (to me), find pieces, parts and set-ups that SOUND amazing, and THEN get some measurements to help understand why.

Well these measurements only tell you what the frequency response of the speaker is in your room. Doesn’t tell you anything about how an amp or parts sound through the speaker.

Speakers are opening up nicely after a day of nonstop playing so I decided to bring out the big guns. Boy this is nice.

Is that an L1? I can’t quite make out the faceplate lettering.

It’s an EL34 but wired as a straight amp and has Duelund coupling caps.

A while back I was messing around and got a pair of these TPA3116 class D modules off Amazon for $14. I 3D printed some cases. With good power supplies these things actually sound really good through the Superminis. They pretty much sound as good as any of the TPA3255 amps I have just less power, but that is not a factor with these speakers as they’re almost 94db efficient.

Sorry, sorry, sorry! 😅😂  I just thought this was really funny as a response (again) 😇 😎


Not to sidetrack at all, those cases look really nice, the clean aesthetic, which printer did/do you use?

It aint a purifi/hypex but still sounds good for cheap.

3D printers, Bambu Labs all the way, always. I have a P1S.
