| The Arm/Cartridge Matching Myth But not one single Peer-Reviewed Scientific White Paper demonstrating the relationship between Resonant Frequency and SOUND...🤯This statement is false and blatantly so. If the mechanical resonance ('Resonant Frequency' per above) is too high, the ... | |
| Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil I forgot to add that IMO part of the issue with bypass caps has to do with the size of the coupling cap you are bypassing. Generally speaking I've not liked what larger coupling caps do as they impose more coloration. But in some cases they have t... | |
| Tannoy Speaker Owners I’ve read that Class D amps have a deeper bass than tubes. With the speaker rolling off at 33 Hz, this is no worries. Our tube amps go full power to 2Hz and on the right speaker play better bass than most solid state amps. Its all about matching t... | |
| When do the new Atmasphere Class D come out? @gdnrbob We've got a UV-1 in the shop right now that a customer sent; a friend of his that borrowed it said it was humming. We can't get it to do it; I think the problem is either cables or its very near a power transformer of some sort.Regarding... | |
| Kiebert 300B 100 watt amplifier Those power ratings are before the IHF stepped in during the early 1970s to standardize power ratings, by creating the 'RMS power' rating.By that method of measurement the amplifier at the first link will make about 50 watts. That circuit could st... | |
| What creates the effortlessness in sound reproduction? I'm sorry for my ignorance but I am not sure I understand this correctly. Do you mean that in an experiment of several systems which are playing at 100dB, some system will be louder than the rest? @quanghuy147Â No. Some systems will **sound** l... | |
| Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil Experience and try for yourself.  This is the only way to know for you . @grannyring A lot of people are of this opinion. I've just found that the more transparent the system is, the more you hear that paralleled caps don't have the desired effe... | |
| What creates the effortlessness in sound reproduction? This is all about distortion.If higher ordered harmonics not part of the music are present, the ear will sense them as brightness and harshness. If there are room reflections that are occurring at less than about 10mS or so, the ear will sense the... | |
| Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil Could someone explain why adding a 0.01uF capacitor in parallel/bypass with a 2.2uF capacitor improves sound quality? @kalali  It doesn't! Any capacitor has a certain 'speed' defined by a combination of its dielectric constant and series resista... | |
| How much will you pay for an exotic cartridge.... A manufacturer that bypasses his distributors in a given country will not have any distributors in that country for long! So it is in their interest if they are in the game for the long run to make sure their product isn’t being gray marketed by o... | |
| Cartridge loading When you say, RFI, are you talking radio frequency interference, or in general, electro-magnetic interference (EMI)?@antinn Thanks for your comments!RFI, not EMI. The RFI is caused by the tank circuit created by the cartridge inductance and tone a... | |
| Full feature preamp $1500 ^^ the SP8 will need complete refurbishment. | |
| Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil With tube gear where the input impedance is typically 100K or more, a 0.68uf coupling cap is fine.The smaller value you can get away with, the better the cap itself will sound (and no need for a bypass). That is why we have a direct-coupled output... | |
| Cartridge loading @intactaudio That is what the 47K input standard is supposed to be for- a slight amount of damping. I don't see in the text you quoted how the cartridge was set up- was it driving a very high impedance as a control or 47K?@antinn The interesting ... | |
| Considering going back to Solid State Heat really isn't a thing with tube preamps. They make a little heat but its not significant- if that is really a problem you have much bigger fish to fry! Reliability is another thing, but IME you can leave a tube preamp on for some pretty long t... |
