| Looking for more detail in a speaker Pi*r^2calculate 1, then 2, then subtract.Now you have the volume of air moved. Of course there are myriad other factors from magnet efficiency to rigidity to.....But if all you're asking about is diameter, there you go. | |
| High end stereo preamps? Worth it? @sokogear-@itsjustme - no - I was talking about going straight from a phono stage to a power amp. Not clear what you are saying "no" to. Precisely what i was talking about. RIAA --> Power amp is "no preamp". No matter just a bit confused. | |
| High end stereo preamps? Worth it? Is anyone aware of these types of components, and have you heard them, and are any available at a more reasonable price level? Funny, if you are asking about an integrated amp, with a direct plug-in RIAA option, it's my current design project. (... | |
| High end stereo preamps? Worth it? Ah the "great preamp vs no preamp" question.So how can anything be better than zero distortion? Its tough, but possible in one of three ways. 1. It adds a euphonic distortion that you like.. nothing wrong with this, its what a Piano's sounding bo... | |
| High end stereo preamps? Worth it? Worth is a subjective question. Relative worth may be easier to deal with. I always ask the question "if i have $1000 to spend, where do i get the biggest benefit". That depends, basically, on where the biggest problems are. And its exactly why ... | |
| Amplifier warm up Actually, i agree with both the OP and N80.Yes! solid state warms up, and over a 30-60 minute period the majority occurs. Many solid (state) reasons.That said, everything sounds better after a glass of wine, or with stable blood sugar or whatever.... | |
| Can someone tell me what wrong you already swapped tubes. You swapped the entire amps! | |
| Can someone tell me what wrong If every test is as you say, I'm baffled. The ONLY answer is that a) its the amps and b) they both changed at the same time. And suddenly.This is very unlikely.Speakers don't generate hiss.Passive components don't generate (meaningful) hiss.You r... | |
| Amp repair cost — is this right? It's the ones that go off on a tangent with esoteric replacement parts that make me pause. Yes, missed the point of re-capping 'lytics whcih are without doubt already bypassed with poly-something film :-) | |
| Amp repair cost — is this right? Building my own I am free to use polypropylene power supply capacitors instead which have an unlimited shelf life and do not wear out. For the 1kV power supply to my final stage of SET amplification I use polypropylene capacitors rated at 2400 ... | |
| Amp repair cost — is this right? In Australia a "reputable repair shop" charges $115-$130aud per hr that $80-$90usd. Like I said it would take a tech that "cares" about a day to do this properly heat soaked and biased back up. And then there’s the "quality" parts 16 x large po... | |
| Amp repair cost — is this right? @teo_audio:$100 to take it apart, remove the PCB, remove all the caps, buy new ones, put them in, pre-test, re-assemble, final test?If so I will hire you as a tech tomorrow :-)G | |
| Amp repair cost — is this right? I speak with some knowledge since i’ve designed many commercial amps, and recently re-capped, mostly as a favor, a dozen or so ~30 year old units that i know the owners of and were sold under my own label(s). Its a total PITA.Just an aside, i rece... | |

| Speakers Nominal Power handling/Amplifier Since much has already been said, i’ll keep this brief.First, Millercarbon hits the technical highlights. The exponential power relationship with volume is the primary reason though, why power ratings are overblown. This is because of the necessar... |
