  3. Yeah, it was pretty fucking amazing. I like all 3, but kd lang stole the biggest highlights with Helpless and Constant Craving. Different show, but very similar performances: The musicians were great, the banter between the self-proclaimed "Sister Wives" was lots of fun, and each performer got to show off a lot, with some great harmonies by 2 or all 3 at a time on many songs. Two encores, with the second starting off with Patti Smith's People Have The Power. A great great show, threatened early on by rain, but it cleared before they came on, and even had a nice rainbow as a prelude to their show. Great entertainment, well worth the see!

  5. Absolutely agree as a technical matter that being able to swing full voltage at 20 kHz is better than not being able to. The SRX Plus, for example, is not able to do so, and in fact, as I posted in that thread, actually measurably rolls off at lower frequencies as the output voltage increases (it's flat at 100 VRMS to over 20 kHz which is pretty loud, though). BTW, KG's calculation is actually a minimum estimate of the current required, because a stat headphone is not a capacitor - it makes NOISE, e.g. music, which means it has to consume ADDITIONAL current over what a capacitor requires. However, as Dr. Gilmore points out, the question is, how loudly do you listen and how much actual audio content is there at 20 kHz. There is actually some data on the latter point. A number of years ago, Peter Baxandall and Nelson Pass both measured slew rates in recorded music and both came to similar conclusions, namely that an amplifier capable of reproducing a 6 kHz sine wave (yes, 6 kHz, that is not a misprint) with low distortion is adequate for music signal, because of the natural roll-off of musical instruments. Note that this was equivalent to the fastest music signal they found, and that everything else they measured was SLOWER than that. More recently, Baxandall published that he had found a recorded music signal that required an amp to be capable of reproducing a 15 kHz sine wave with low distortion. That is significantly faster, and in fact is within striking distance of the 20 kHz signal at full output voltage requirement - however, it must be noted that this is a unique event, and for almost all music the lower requirement is adequate. Is it appropriate for a state of the art amplifier to aim for the more stringent requirement? Absolutely! Will the lower requirement suit the needs of most? Probably. Of course, extra headroom is always nice - but there is a cost. For Stereophile Class A, the cost is always worth it, almost by definition. For Stereophile Class B, the question is, how much can you cut back for as little sonic cost as possible. Finally, if you listen at lower levels, the requirements decrease accordingly. This is why spritzer suggested to Tyll that he listen to electrostatic headphone amps at high levels to differentiate between them - because this stresses the amp the most.

  6. Just needs a good DAC for 20mA and it's perfect for SR-009s.

  8. I posted this over there, will post here. if I had time I would find to do a way to do the graph that shows frequency response relative to output voltage, maybe in a few days if people don't get it so here is how this works Required Slew Rate = 2 x π x Frequency x Peak Voltage x K we can argue about K later, different people have different ideas about the value.The load is a capacitor and it takes a particular amount of current to charge/discharge the capacitor at a particular frequency and voltage. Lets reference the maximum peak to peak output voltage of the amplifier at 1khz as 0db. Now lets calculate what amount of current is needed to do 20khz at 0db at the same peak to peak voltage into one standard headphone load, 120pf Now lets figure out (and this part gets complicated) how much more current is needed to guarantee .01% thd at 20khz at 0db. taking into account the open loop gain. Its clear that some of my earlier amplifiers with output currents in the range of 5ma to 10ma cannot do full voltage swing at 20khz. But will do a full flat frequency response at less than full voltage swing. So the question is how loud do you listen and how much actual audio content is at 20khz relative to 1khz. It is my opinion that 20ma however is enough to do full voltage swing even with 500V power supplies. 2sc4686,2sc3675,2sc5466 etc, cannot do more than about 10ma before they eventually blow up. Even with lots of heatsinking. And ixta3n120 has so much output capacitance that even with impossible current numbers it could never get there from here. Cree C2m1000 however can run at at least 30ma at 500V power supplies, is ultra low output capacitance etc. So is the current flavor of the decade output device, till something better comes along. A couple of people think that the carbon is a bit bright at 20ma, and have turned their units down to 18ma. This is one way that the amplifier can be tuned. The performance of an el34 at 20ma begins to effect the lifetime of the tube. Significantly. emission labs 20B work fine at 20ma, but have a stupid price and questionable long term reliability. There is no free lunch.

  9. Still working with my non-birth year starter... I am baking two loaves - twice a week these days - and sharing at work. -- This is one I liked - and had good results. Oat Porridge AP - 600g 50% Whole - 300g 25% Oat - 300g 25% H20 - 950g 79% Salt - 29g Oat Porridge 600g Bake was @500 covered for 15 Minutes @500 uncovered for 10 (forgot to turn oven down) @450 for 5 @450 on oven rack for 25% They were heavy and big suckers.. But very nice and the bake was good. Crust was nice and crisp - crumb was moist (expected for porridge loaf), but not too sticky. There was a lovely sweetness on the palate - rest of the nuttiness and oatiness are light but nice. bread pics -

  10. The Blue Hawaii PS will work fine with the grounded grid. The requirements for the +/-15V supply are identical.

  11. Thanks -- after several hundred loaves now - I am starting to get the hang of it, getting to know how to read the dough during the fermentation, how it 'feels', how it looks, how it reacts. Every loaf I make is an experiment - different methodology - different mix - always learning ... hope to continue.. Cheers

  13. Yep. The SR-009s with the Carbon is my preference over the BHSE, the Carbon is right up there at just about DIYT2 level. From my listening tests the Golden Reference Low Voltage supplies have also pushed performance considerably, it’s exclusion from a build is something that may weigh in.

  14. Vice-presidential nominee Mike Pence's daughter casts no reflection. What could possibly go wrong? Members of Orlando's Shakespeare Theater are building "angel" costumes like these to block Westboro Baptist Church members at memorials for the Pulse shooting victims. What could possibly go wrong? What could possibly go wrong? Leningrad, 1971. Milky Way and French Alps, Chamonix. Doors in Venice. 3AM in Finland. Ice Lakes, Colorado. Sunset Over the Matterhorn Summer 2015. Autumn in the Adirondacks.

  18. So I revised a method that I put aside for a while. Stambler method. http://stamblersbread.com/about.html The starter had been in my fridge for months - not being used or touched. Took it out on Saturday - refreshed it - it seemed to come to life - So yesterday I fed it again and turned it into a couple loaves. And wow I really liked the results. simple 70% All Purpose - 30% Whole Wheat - 75% Hydration. Made pretty (and tasty) loaves this morning.
