    PE now sells more units from Visaton, including the European-loved B200. There is also a large buyout of FX-Audio gear...

    Later,

    Just a couple, there are more-

    I will likely have a pair of B200's on my porch sometime this coming year. They could make some really nice open baffle dipoles.

    Did you see the Visaton B100 and B80 also? Very nice looking specs on those too.

      The b200 is only a single driver and not a coaxial but can reach 18k? Wow.

      Just got an fx202a in to drive a pair of Pico for the nephew's Christmas. Hoping to get the Pico finished up early enough to run them and the fx202 through the paces. IIRC, the fx202a uses the tda7492pe chipset. It is supposed to have less distortion than the tpa3116 but the tpa3116 seems to have developed a following while some 'better' chips have not.

        I bought two of those little $9.99 TDA7492 amps to power my desk speakers at home & work. I figured I could use the cases for something else if they turned out to be junk - they are actually pretty decent. The only negative is the turn on thump. I went to buy more for other folks a few weeks later, but they were NLA.

          I was curious too, got one of the black ones, they sold out first. Pretty much similar to PE's now defunct little mini amp but with a toggle switch and power indicator light. Sounds pretty decent for being the size of a pack of cigarettes. Did your power supply come in a separate box too?

            Yeah - those power supplies were in boxes much bigger than the amps. I was wondering why the amps didn't just use some small binding posts - then you open the box and see how tiny these things actually are. It looks kind of funny sitting on top of my FX dac/headphone amp.

              This is just my $.02. Take it as that from an old fart with questionable hearing and tinnitus.

              Initial impression of the fx202a compared to the Dayton dta120 driving the Sadies (see pic) from Spotify and FLAC files through Foobar, both decoded with an Aune dac.

              The very top of the treble is there. Overall, the treble isn't really forward or harsh, in fact maybe it's just a bit softer but it remains full and present. The very top of the treble is also present. Hearing some faint 'clinks' stuff that was missed with the dta120. Brushes are just as full as before but softer and maybe hearing a bit more into the end of the brush stroke. Is the decay cleaner? Am I able to hear further into the recording? Harsh recordings still sound harsh.

              Mid is ok, nothing to complain about. In Natilie Merchant>Peppery Man everything is as it should be. Her voice sounds fine with the stage presented as it should be. At 1 minute into Peppery Man, there is a baritone? voice that emanates just a couple feet behind the right speaker with the dta120, with the fx202a it is positioned further behind the speaker being plastered solidly against the rear wall.

              Diana Krall>Peal Me A Grape: She is center stage standing solidly on the rear wall 5 feet behind the speakers with that big violin thing just to her right maybe a foot forward her position. The piano is even with the front of the speakers having a U shape where the middle of the piano register falls behind the front plane of the speakers. Both the dta120 and fx202a do this with the piano.

              Roger Waters>Amused To Death in QSound; Going to go out on a limb here and say this is probably one of the most sought after disks for demoing how well a pair of speakers can portray the soundscape. Music comes from everywhere but the speakers. The fx202a did a fine job here.

              Bass is there and tight, maybe a smidge looser than that of the dta120. After being surrounded by large heavy amplifiers for decades, it simply amazes me how darn clean and tight these tiny flea sized amplifiers are when it comes to bass.

              Without measuring, the dta120 sounds more powerful. Not a lot, but it does seem to go louder with more ease with a bit more slam. I doubt either of these amps come close to their rated power, but they make very good use of what power they do have.

              I like the fx202a. Although these small chip amps are not the most bestest amps ever, color me very impressed with how well they sound for so little $. Just my opinion, but I feel the advent of these tiny chip amps, not just these but the entire crop of them and further refinement, has advanced our affordable sonic pleasure significantly from where we were less than a decade ago.

              The Sadies are the two small two-ways using a FaitalPro 5fe120 and xt25tg30. The crossovers for them are the pile of inductors/caps/resistors/jumpers below them. You can barely make out the tiny dta120 and fx202a atop an Acurus a200x.

                Just be sure that you have that vise handy to keep your head from moving! Here's the B200's radiation pattern at 18000 Hz:

                  Meh, my all time favorite speaker is an Apogee planar. The window is oh so small but the view is beautiful.
