| Best Analog for $10K I posted that way because the playback process in R2R does not develops so many distortions as the LP playback whole process and because in the tape was not recorded the RIAA eq. curve and low registers comes in stereo.@rauliruegas Just so you ... | |
| Coincident speakers 14 Ohms - What amplification to use when streaming Tidal. The 14 ohms impedance isn't problematic for any amp. It does not matter what source you use or what music you prefer. But you will need a bit of power since your music room is a bit bigger. So the SET idea is right out (and FWIW, most of the Coinc... | |
| Best Analog for $10K I'm refering with analog to LPs, I'm not talking of analog tapes.the LP has wider bandwidth, lower noise and lower distortion than tape. So this statement seems a bit conflicted.@imgoodwithtools My recommendation is also the Technics SL1200G. Th... | |
| Excellent article in Stereophile The sound that no doubt measured best. Of that I have no doubt. I've been maintaining for some time that harmonic distortion should be measured according to a weighting system that assigns a low number to lower ordered spectra and a much higher nu... | |
| What Class D amps will drive a 2 ohm load Can I make the same comment that higher impedance is receptive to noise, in the same context that lower impedance adds distortion.Probably not. The impedance of a 16 ohm loudspeaker will not affect noise floor at all. But many 16 ohm loudspeakers... | |
| What is wrong here.. on Audiogon? Your question was easily answered with concrete examples. The other thread you mentioned wasn't. So it got more response. | |
| Stylus-Drag..Fact or Fiction? Anyway, who do you send the masters to for pressing?@mijostyn I've found that if the mastering is done correctly most pressing plants can do a pretty good job. But QRP stands out as the best (their pressings have noise floors that easily rival Red... | |
| What Class D amps will drive a 2 ohm load It's also interesting that Stereophile didn't bother reporting specified power rating at 2ohms, but did mention THD rises into 2ohms at higher frequencies.This is true of all amplifiers; if high fidelity reproduction is your goal, lower impedanc... | |
| Time to buy a class D amp? Like some one said here they have one that goes to 1mhz in bandwidth!! this one will certainly over time cook or quickly the tweeters voice coils. I even leave them on most of the time as recommended. I don't think this is a good practice, as y... | |
| Exploring Preamp options for the Pass XA25 OK- I had to look that one up. With a 47K input impedance a large number of single-ended tube preamps will drive that with no worries. You already have some excellent suggestions in this thread. Do you need a phono section? | |
| Time to buy a class D amp? Read again from Texas Instruments, far more authoritative than you Ralph, and this is still with the output filter in place, but with it set too high, without it and you have a tweeter meltdown. From Texas Instruments:On output filters of Clas... | |
| Time to buy a class D amp? From Texas Instruments on output filters of Class-D amps that are set too high corner frequency. "A concern with the switching waveform being dissipated in the speaker is that it may cause damage to the speaker" This is what happened to my mates... | |
| Time to buy a class D amp? Go near one with a portable am radio tuned off station around 600khz (or whatever your switching frequency is) and see what you get out of the radio. If you look at their output on a oscilloscope they are more than just noisy as heck! And that ... | |
| Crackling and hiss - Preamp tubes not seated right? @jayctoy I don't see why not! | |
| Amps with meters ... We've had meters on our amps for the last 43 years. They were initially there to set up the power tubes (bias **and** DC Offset, since our amps have a direct-coupled vacuum tube output). This also allowed the user to test the individual tubes on t... |
