| Why 24/7 warm-up period on amps? Atmasphere - sorry for using word "waste", since filament makes it all work, and overstating losses. With my tendencies to exaggerate 50% error ain't bad at all. | |
| Why 24/7 warm-up period on amps? Paperw8 - Voltage ratio in electronics is, and always has been 20log(v2/v1). Pretty much anything other than power is always 20dB(k2/k1) including sound pressure, sound level etc. -3dB of voltage means 0.708 of a value. 12dB means ratio of 4, 20dB... | |
| Acoustic Zen Adagio Speakers? I was planning to buy Adagios but ended up with amazing Hyperion HPS-938:http://www.realhi-fi.com/pdf/HFNhyperion938.pdf | |
| Why 24/7 warm-up period on amps? "they may only be on for a few milliseconds per cycle" This current is not only huge but have very high rms to average ratio heating windings, while high frequency content heats up the core of transformer.This huge current spikes' amplitude and ti... | |
| Why 24/7 warm-up period on amps? dB=10log(P2/P1)=10log((U2^2/R)/(U1^2/R)=10log(U2^2/U1^2)=10log((U2/U1)*(U2/U1))=10log(U2/U1)+10log(U2/U1)=20log(U2/U1)Al, Dave, please leave some beer for me. | |
| When is digital going to get the soul of music? Mekong56 speaks death in his 666 post - be careful! | |
| All Amps Sound the Same.... To be more clear:Instead:"Using cables longer than 10ft exposes your amp to electromagnetic pickup of everything below 10MHz"should say:"Using cables shorter than 10ft protects your amp from electromagnetic pickup below 10MHz"My logic had better d... | |
| All Amps Sound the Same.... Frogman - nobody is talking about complete picture but rather about step in right direction. As for the wire and interference. Lets for a moment assume that we're talking about speaker cables. Interference, usually high frequency, can be capacitiv... | |
| All Amps Sound the Same.... Onhwy61 - I'm only saying to avoid products that measure too well for the price, because something has to give and often it is sound. Soulution monoblocks look very impressive but I'm more withing Rowland 625 range. I agree, that some kind of dyna... | |
| All Amps Sound the Same.... Onhwy61 - Rowland amps sound great because of Jeff Rowland and not any measurements. Atmasphere amps measure quite bad (THD=1%, DF=1) but sound great. I don't want to go into details why "feature massive use of negative feedback, outrageously good... | |
| All Amps Sound the Same.... "but if you want to electronically reproduce music, then the measurements should be the dominate method of understanding."Onhwy61 - In order to get pleasant sound from SS amplifier you need to elimnate TIM (transient intermodulation) distortion th... | |
| best wood for speaker cabinets ? oak,cherry, balti I found this article that makes extensive comparison between birch plywood and MDF: http://www.tnt-audio.com/clinica/cabinet_walls_e.htmlTo my surprise they found birch to be better. 11-ply Baltic Birch plywood might be good. | |
| Neutral Sounding Silver Cables? Acoustic Zen Absolute is silver with 1% copper in oversized foam Teflon tubes. Very neutral cable. I got 0.5m XLR for $600 used perhaps because of uncommon length. On the other hand 2x shorter cable is 2x better cable. | |
| If your whole system costs $40,000.... At this price point it is cheaper to house Symphony Orchestra in the living room - nothing beats real thing. | |
| best wood for speaker cabinets ? oak,cherry, balti There might be different reasons why manufacturers use birch. One of them is perception of quality - hardwood vs. MDF. People often choose kitchen cabinets with plywood shelves not knowing that MDF works much better (less sagging). The other reaso... |
