| Your advice to speakers designers My 2 cents:Keep the impedance and phase angles reasonable. The last thing you want to do is make **any** amplifier work hard, as to do so makes more distortion and it will most likely be audible as harshness and loss of detail.As an example, many ... | |
| Impedance Question? Maybe this was mentioned and I missed it but is there a simple mathematical relationship between the value of the coupling capacitors and the output impedance or other variables are in play?There is- Zout+C, where C is the impedance of the cap ... | |
| Just retired and want to get back to vinyl listening Suggestions for cartridge choices are welcome. Considering .....Cartridge manufacturers really don't want to admit this, but the ability of the tonearm to properly track the cartridge is far more important than what cartridge! The Triplanar is one... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? ok, now I’m curious - where can I read about the advances in understanding human hearing & perception thereof (psych. not physiol.) since the 1960s?You gotta pound the heck out of google. Here's a fun one:https://pdfs.semanticscholar.org/2f0... | |
| Help with a new Tube headphone amp blowing fuses , just got my Yamamoto tube headphone amp back from the shop here in Houston and the diagnoses is that it has a bad transformer, that he could not get parts and that he would discard it for me and save me a trip.Red Flag!If the power transforme... | |
| Impedance Question? I’m curious to know what these issues are with direct-coupling are since I may go this path with the SLP-98.The Cary employs direct-coupling but not at its output- there it uses a conventional coupling capacitor.But to answer the question, direct-... | |
| Just retired and want to get back to vinyl listening curious as to why more TT/tonearms would not have balance outputs and equipment inputs for these in various equipment be the xlr balanced inputsThe idea of the cartridge being a balanced source was introduced to home audio in 1989 by Atma-Spher... | |
| PrimaLuna Dialogue Premium Preamplifier. DESTROYS SPEAKERS!! The OP said specifically it was DC and that he damaged his speaker, not his amp. << shrug >> Not a big deal. Right on both counts- but we sorted out pretty quickly that it wasn't DC- his amp blocks DC, so it had to be something else. | |
| Are future improvements in Amp/PreAmps slowing to a crawl? I said it before on this thread and I very much feel this is where the big improvements will be made:One area that is a problem for all amplifier designs is that most are designed to have specs that look good on paper and are not really designed... | |
| Impedance Question? Why would they not use a higher value capacitor if that improves the sound and provides more pairing options? Cost can't be the reason since the price differences is not much. There must be other reasons or design tradeoffs.You are correct. The... | |
| Just retired and want to get back to vinyl listening I do have a question -- if folks would be so kind -- about pro/cons on using the rca line inputs - outputs versus the balanced I/O on some of these equipment pieces -- I have no experience at all on the balance I/O - thoughts?There are several ... | |
| Loudspeakers have we really made that much progress since the 1930s? Your TAD drivers all based on early 1920s designs,the horn of the CAR is just a evolution of a 1940s design. OTL amplifier is from the 1950s sure you improved but you didn't create invent. OTLs: yes I invented my circuit myself. I didn't know ab... | |
| Loudspeakers have we really made that much progress since the 1930s? My speakers at home are made by Classic Audio Loudspeakers. I may have mentioned this on this thread a long time ago.They differ from vintage stuff in several ways. First, the midrange driver, which employs a 3" compression driver coupled to a mac... | |
| Are future improvements in Amp/PreAmps slowing to a crawl? I usually tell people that the room is 50% of the system. There's not a lot you can do with the very best system if the room sucks. Conversely a very modest system can do great things in a good room. If you had the perfect amplifying method - a pa... | |
| Impedance Question? jmcgrogan2 has the best answer +1Our tube preamps don't have an output coupling cap- so they can drive 600 ohms let along 10,000 ohms with ease. The output impedance is the same at 5Hz as it is at 1KHz or 30KHz.Generally speaking though, most tube... |
