| Tonearm microphonics Tapping the tone arm while it as rest will say almost nothing about how it will sound when doing its job. It really is right next door to the address marked 'Red Herring' on Red Herring street. | |
| recommendations for amplifiers that don't emit tons of heat the biggest power consumer in a tube amp is usually the heaters for the cathodeThis statement is rarely true- I think the exception used in audio is the 6C33. For most power tubes - like a KT88- the heat made by the cathode is insignificant compar... | |
| Do any Audio Research tube amps run in class A? Short answer: no. | |
| Sonic qualities of SET output tubes? @inna Ralph, would you like to tell us about disadvantages of OTL amp design? 0.5% distortion at full power is quite an achievement.One thing is certain - more powerful SET amps done right are very expensive.We get that figure without using feedba... | |
| Upgrading amplifiera. We have an update with warranty reactivation policy. We also offer options- higher performance capacitors and resistors. We've had these options for decades, they are easy enough to hear. We prefer to do the work on the amps so that we know its do... | |
| Sonic qualities of SET output tubes? Ralph, besides Classic Audio, what would you recommend to use with your amps? Also, do you believe that short length Mogami RCA cables are just as good as XLR? I mean 2497 wire.If you keep the cables short you can do pretty well with single-ende... | |
| Sonic qualities of SET output tubes? I guess in the golden days of audio weren't most speakers 16 ohm to be more tube friendly in that respect.Of course!1 4 ohm load impedance speakers are easier to design/build.2 An assumption that the majority of buyers plan to use solid state amp... | |
| Bass distortion-Playing LP's only,,,,please help Secondly, most good preamps will pass DC which will of course create havoc with your woofers. This statement is entirely false. No preamp made passes DC!Regarding loading:If loading is affecting the sound, it suggests that the phono section is un... | |
| Has Anyone Heard the (fairly) New Technics Grand Class TT? This is my opinion of course but I would call the turntable 'excellent'. The arm really isn't bad either (much improved over the original SL1200 arm), but is bested by other tonearms, the Triplanar being one of them. I would place the stock arm ab... | |
| Sonic qualities of SET output tubes? What am I missing?Grannyring got it in one- well done!Apparently that this applies specifically to SETs and not to other kinds of amps. For example, despite being zero feedback (like SETs), our amps make a fraction of the distortion at full output... | |
| Price No Object Amps I'm still saving for Sanders monos' ! those will smoke any amp regardless of price. This statement is clearly false like many generalizations, especially in audio. | |
| recommendations for amplifiers that don't emit tons of heat Y'know, if you like the sound you are getting there is a much less expensive option, which is simply to have a vent installed to the outside that allows the heat to escape the room rather than warming it up. This can be done for a few hundred doll... | |
| Sonic qualities of SET output tubes? there is usually a lot of distortion in the recording already. How do you try to correct that? Or you simply live with it and do your best not to make it worse?There may or may not depending entirely on the recording.You certainly don't want to... | |
| Sonic qualities of SET output tubes? @blindjim , all the comments regarding speaker efficiency are spot on.And you are quite correct that different brands of power tubes are going to sound different. Once you settle on a particular power tube type, then you sort out which brand of th... | |
| Sonic qualities of SET output tubes? The difference between tubes themselves is not that profound. They are just tubes and they have very similar linearity and bandwidth. This is not true of output transformers! Here's the problem- the more power there is, the harder it is to get ba... |
