| Question on PrimaLuna EVO 400 Amp: Fully Balanced (Differential), or No? If the amplifier employs AC filaments for the voltage amplifier tubes, a cathode/filament short in a tube could cause that. | |
| Cartridge Loading for a phono pre amp Raul's handwaving aside, I agree 100% with what JCarr has stated, quoted by Raul during his handwaving nonsense above. Loading does not affect the bandwidth of the cartridge, nor is that something I stated. Raul is employing a strawman argument (... | |
| Connecting monoblock tube amps to single subwoofer. Connecting to one speaker only ½ works for mono bass such as on LPs. Master tapes do not have mono bottom. @ieales At 80Hz, the waveform is 14 feet long. The ear cannot know a tone is there until the entire waveform has passed by it, and to ... | |
| Will I benefit from a subwoofer with 20Hz speakers? Sorry being so stubborn, but "eliminate" - no, "reduce" - yes. If you start from +/- 15 db shifts or more in the bass region, which most of us do (look at the measurement the op did), then I’d say there is no way a swarm setup will flatten that o... | |
| Cartridge Loading for a phono pre amp Always start with 47K to see if the preamp works with RFI at its input. If yes (the preamp is unperturbed by RFI), this will get you the best sonic performance. If it sounds better with lower resistance loads, then the preamp does not handle RFI w... | |
| Why do I need power management if I have a great power cord? Here is the latest video from Amir on power cords. This statement is false. Amirm is testing a particular cable- an Audioquest, not all power cords. It would be correct to say 'Here is the latest video from Amir on an Audiquest power cord'. Ho... | |
| Woofer pulsating with no volume , Oscillation issue? @tommypenngotti In that case you have the two most likely candidates: 1) a tube that is making mostly low frequency noise, which would result in irregular motion in the woofer 2) a regular motion is most likely a failed filter cap, even one that... | |
| Woofer pulsating with no volume , Oscillation issue? @tommypenngotti Did you swap the input cables left for right to see if the problem moves? | |
| Will I benefit from a subwoofer with 20Hz speakers? While the vendor's promotion online has been fair and honest the fan boys of this system are out of control. From reading their posts and their attacks of the ideas posted above it is clear to me the fan boys have never heard a well integrated s... | |
| I met this guy in a hotel room.... In the room I speak of was Fritz and his speakers. For under $4,000 he was selling really unique crossover designs with world class drivers. $4k for the parts he was using is basically a song, and to be put together in such lovely sounding speake... | |
| Changed subs from speaker level to XLR after many years. Wow! If your subs have RCA inputs (and not XLRs) Jensen Transformers makes a wonderful product that does the conversion from balanced to single-ended. Its the ISOMAX SUB-1XR (you'll need two for stereo, or else the SUB-2XR if receiving stereo signals i... | |
| Cartridge Loading for a phono pre amp @holmz Back EMF?? No. Any cartridge is a generator of power. When the load on any generator is reduced in resistance, more current can flow. This energy has to come from somewhere (otherwise a new branch of physics would be created...) and it co... | |
| Woofer pulsating with no volume , Oscillation issue? @tommypenngotti A low frequency oscillation as you see here can be caused by failing filter capacitors in the power supply. If this is the cause it will get worse- the condition is known as 'motorboating'. If this is what is going on, I'd have b... | |
| Will I benefit from a subwoofer with 20Hz speakers? What you say is true, however if you were use a low cutoff filter at 40Hz. With most music I doubt if you could hear the difference. A subsonic filter cuts in about 40 Hz and I could never tell the difference apart from stopping the excess movem... | |
| Cartridge Loading for a phono pre amp @judsauce The industry spec is 47K for all cartridges. When you load the cartridge at a lower resistance you are asking it to do more work (produce more power to drive that load). Even though its a tiny amount of power, it will make the cantilever... |
