| Solid state to tube Have the speakers ever been recapped? If not, start there. 20 year old caps are well past their sell by date. Replace ALL with polypropylene or PTFE. Going to a dealer is a waste of time as they do not have your speakers, cables, room or the rest... | |
| To couple, or not to couple, that is the question NO! If the isolation stops the transmission, the stand can't 'ring' | |
| To couple, or not to couple, that is the question "Spica TC-50 on shot filled spiked stands and 4 Sorbothane pucks to stands." See above. RE: IsoAcoustics Frequency Response Testing at the National Research Council of Canada The graphs show the vibration in the stands. They don't show the ... | |
| To couple, or not to couple, that is the question It's complicated. ALL components on Sorbothane. IMO, and especially for bottle rockets, all components should be isolated. In an earlier life in previous concrete slab home, components were in one room and speakers on spikes in another. Many good... | |
| Question About Capacitor Upgrade in Tube Amp The elephant in the room that no one notices is Power Supply Impedance and Phase. It is perhaps the most important and neglected aspect of HiFi design. Capacitors have two frequency dependent properties, ESR and ESL, often ignored by engineers an... | |
| Question About Capacitor Upgrade in Tube Amp I can definitely hear a difference in the clarity of vocals and the separation of instruments between the X7 vs the X9 and X10. So let’s see how this upgrade works out once I get the parts. There’s a lot more going on than just the caps. Power,... | |
| Question About Capacitor Upgrade in Tube Amp It's more complicated than just hanging a film cap across B+. If you assume the designer knew what he was doing, had good ears and related equipment, you could make things a whole lot worse by making willy-nilly changes. Too often audiophools mak... | |
| PSA: Short Unused Speakers and Subs in the Listening Room The extra speakers myth was debunked in the 80's by the Boston Audion Society with none other than Linn's Ivor. Look it up. Multiple subs are for more even bass throughout the room not accurate bass at the LP. Read Toole's book. see ieLogica... | |
| Install A Dedicated AC Line at home Almost no home system requires more than 15A. A properly installed 15A can supply 20A continuously for about an hour. Other than class A, nothing draws anywhere near that much power. It’s a bad idea to run multiple circuits for a HiFi, doubly dum... | |
| Everything matter in the audio chain. Tests prove it! Yawn. 🙄 News, no. Perhaps in the 70's... See ieLogical CableSnakeOil for some of the reasons why. | |
| Help finding a subwoofer Today I threw out a Storm iii and a Stadium iii. If the drivers are still good AND you can retrieve, you can remove the amps, fabricate a filler [or just add external connectors] you can use a 2ch class D* and DSP to blow the doors off the REL ... | |
| Help finding a subwoofer how the input of a subwoofer is able to deal with signals from all amps in a high level input The sub high level input is high impedance, so only uses voltage and very little current from the power amp. Level control adjusts. A hundred-fold i... | |
| Help finding a subwoofer do you mind to elaborate on what you meant when you wrote preserving the damping factor at crossover frequency When using active crossovers - which entails removing the passive in a multiway speaker - the amplifier is connected directly to the ... | |
| Help finding a subwoofer I believe in not altering (DSP etc) the signal. It adds distortion. No it doesn't. CD digital output into a DSP offers the ability to exactly tailor the XO frequency and slope to match the drivers, something that is extremely difficult with pas... | |
| Help finding a subwoofer 'Full Range' speakers seldom are. My current speakers are 25Hz ±4dB in a typical room. Main woofer amps are 200w monoblock. Adding a 40Hz first order Butterworth effectively doubles the woofer 'music' power and transient response is much better. ... |
