| Why are most High End Amps class A If anyone is interested there is a master class lecture by Douglas Self on audio amplifier design. His talk is interesting for its lengthy discussion of distortion mechanisms and the new Cambridge 840 XD design which he mentions briefly (a kind of... | |
| The Next Level Yep, those who escaped the merry-go-round know exactly how you feel, every day, day in day out, hour after hour. For those who haven't got there yet - keep trying- as this place does exist. | |
| Focal and Dr Who? Have you seen the Beolab 5? | |
| great sounding cds to audition new speakers Precisely, bring the music you like. When I audition speakers I intentionally bring some CDs that I like that are garbage to see how the speakers handle them. Definitely useful but I'd be careful selecting speakers that way. If the audio quality ... | |
| DIY balanced interconnects I second Kirkus about the dubious need for 600 ohm termination resitor over short distances. However, I agree with Ralph that if you want to go exceptionally long distances then 600 Ohm should get better results. Horses for Courses.What length doe... | |
| Speaker Technology over the last 10 years Active Speakers have become more popular (this design topology has a lot of advantages in terms of lower distortion, better accuracy and eliminating the interface crap shoot issues between finding the right amp to suit a given speaker). Speaker tr... | |
| You know you're an audiophile if-- Your are at a hot strip club with the boys and they are drunk, rowdy and ogling. Meanwhile you sit back and close your eyes simply enjoying the music. Later you remark - I think that was the original version of "The Stripper" recorded by David Ros... | |
| Why are most High End Amps class A tests show that underbias and overbias causes increase in distortion Agreed but I don't understand the point? Of course you have to match the bias precisely between both sides as otherwise you'll get loads of higher harmonic distortion. However y... | |
| What does microphonic tube sound like? Mofimadness,Good point. I stand corrected. The higher gain stages will make pre and pre-preamp microphonics more audible. However the bigger tubes are actually more susceptible to it.Most people like the microphonic sound. In David Gilmour's studi... | |
| Why are most High End Amps class A And you're correct in the assertion that increasing bias doesn't improve the problem, it just increases the signal level at which it occurs. But it does reduce the audibility of the problem. You now have distortion only when the output signal is ... | |
| What does microphonic tube sound like? I expect The Linndisk is overdriving the new preamp and this produces distortion - especially on a modern "loud" CD but less so on a CD made in the late 80's...The PS1 may simply have lower output and therefore it does not overdrive your new pre.M... | |
| Transport for DAC Benchmark do not recommend to use the Volume pot at less than 9 oclock as it may cause slight channel imbalances when used at extremes (same goes for any volume pot actually) - I think I read a comment on Headfi.org by Elias Gwinn about this very ... | |
| are all amps equal Kijanki,There is a lot of distortion in power supply transformers - AC power has all kinds of terrible harmonics to begin with and can often look more like a square wave than a sinusoid - but who cares - the idea is to prevent all this stuff from ... | |
| New to Classical Music - Album to try first?? Shostakovich Symphony No. 5 Agreed - the Lorin Mazel version with the CLeveland Orchestra is OTT! It may not be the moving interpretation but it sure is fun. | |
| Transport for DAC My power amp (Rowland 102) has only XLR inputs rated as 40k impedance. 9pF with 1600 ohms of output impedance makes fc=11MHz. It has to be something else. It has to be something else.I agree 100% - which is why I asked. It does not make sense unl... |
