HMMMMMM…Tubes. What amp you running?

I'm in the Budget-Fi realm, so there are no fancy toys here.

It's just a little Qinpu A3 hybrid with a pair of GE JAN 5670s drivers to a pair of Dayton bookshelf. It's all we really need in the shop for music.

At home I run a Little Dot MK IV with a pair of EI Yugoslavia 6HM5 drivers and 6H30Pi-EB outputs to either the beyerdynamic DT880 Pro's (250Ω) or German Maestro 8.300 D Pro's (300Ω) depending on my mood.

Sweet.

Use a Bryston BHA-1 with my office setup . DAC is the TEAC UD-501 with a PS Audio GCPH phono stage to compliment the Technics SL-1210 M5G. Crappy picture

LCDs and HD800s, the best of both worlds!

Ikea table legs for hangers?

Look at the freaking wobble of that platter! Ugh!! Wow and flutter would be through the roof. Neat looking but a novelty.

If cost is no object, look no further than the Clear Audio Statement. 800 lbs and roughly $200k US. Price includes a small crew to deliver and set up. White gloves are extra.

The McIntosh gear in that video is amazing as well.

Seriously! At 2000 watts per channel, 8000 watts peak, the hydro bill would also be impressive!

It depends on if the speed of the platter is affected or not. Can't tell visually and if that is the true audio, I can't detect anything. The wobble look of the platter could be the balance being off. Although I can't tell if it affects the audio or not.

Wow and Futter is measured at 0.17%. In comparison, the Technics is 0.01% and the 800lb behemoth Clear Audio Statement is 0.03%. 0.17% is not bad, but not great either – it is pushing the acceptable limits and what I would consider to be a tad high for a $2000 turntable.

But there is more to a turntable than speed accuracy. It needs to deal with all types of resonances and mitigate so that they do not turn into distortion. Platters are always fixed and spin on precision bearings. This eliminates movement across all planes, up, down, side to side. Any suspension that maybe employed to help eliminate resonance are engineered into the plinth. This allows both platter and tone arm to move in unison, as depicted in the Clear Audio video. The Mag-Lev is dealing with opposing forces – tonearm is fixed to the plinth and is forced to track a bouncing platter that is moving across multiple axis.

Novel idea and I applaud their ingenuity – but for $2 grand, you could definitely find something better and more flexible.

Back to your BlueTooth question, Willie. I bought a cheap, $10, dongle for this craptop a while ago so it's probably a few versions behind in BT connectivity. It works fine with my cheapie BT headset and crapolla hearing, tinitus does "wonders" for hearing. While those higher end ones might be fnd for younger folks with good hearing and audiophiles, I don't think you'd notice a heck of a lot of appreciable difference if your ears as as bad as mine.

I would reach out to sabastianbach – he was in the works of developing a Bluetooth atomizer. Don’t know how that is working for him, but perhaps he could incorporate audio functionalities into that as well. Who does not want a singing, wireless vape!

Let's see, instead of mw/sqm we're talking W/M. I'm sure the FDA would approve that when people worry about cell phone RF emissions and high voltage power line radiation. Interesting concept that would leave the person trying to vape with it getting cooked like last night's chicken in the microwave.

Doesn't that fall under the FCC jurisdiction?

high voltage power line radiation

I was called in on a habitat for humanity house where people were getting shocked from touching the guttering downspouts. Usually this is a nail or screw that penetrated a wire. Not in this case, I even had the utility company disconnect the secondary at the transformer after I had shut off the main breaker without resolving the problem. The metal gutter went completely around the house so was in effect a single winding coil isolated from ground. It was coupling with the 345kv lines that ran through the back yard like a transformer secondary. Got an engineer involved at that point. All guttering, soffit, and facia were replaced with vinyl, I grounded the duct work, garage door rails, and numerous other metal items that the engineer had me ground. I don't wear a tinfoil hat about such things, but I certainly wouldn't live there after personally experiencing what was going on. Interesting thought however would be to have giant ring of wire loops in the backyard hooked to a voltage regulator.

There are stories about people using coils under high voltage transmission lines to "steal" power. It could probably be done but would get tricky depending on the load on the lines at any given time. I can say that I have taken an eight foot fluorescent bulb out, stuck one end into the ground under a 250KV transmission line, at night, and the bulb lit up, full brightness.

I have a similar problem here but it's RF related. There's a 25KW commercial, AM, broadcaster about two or three miles away, as the crow flies. I had to put bypass caps on all of the X10 switches to keep the pilot lamps off when the switch is off. The RF has even been enough to make LED floodlights pulse fire as their caps get charged from the RF field. Stray power, like that, can be a problem. Everything metal in substations is grounded to protect the people working there from induced voltages like that.

I received my Fuchai Squonker 213's today. No TCR setting just ss316, ss317, Ti and Ni. I made it work,what a tiny bottle.
Edit: Watched a couple of reviews where the reviewer tried to take it to 150 watts and it would spit out "Low Battery" and drop to 95 watts. With a Samsung 30T and 20S I was able to fire it at 150 watts. I would like to have measured voltage off the atty posts but didn't, maybe another time.
