| 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... | |
| Why do I need power management if I have a great power cord? To atmasphere: I’m puzzled by your comment that this Nelson Pass quoted 48 Amps is “how much current is present when the power supply of the amp is shorted. It’s available to the output section in the form of charged capacitance. This is used to ... | |
| Looking for warm tube preamp (should pair well with Pass power amp), budget $6000 The 6H30 is a frame grid triode, and like all frame grid triodes (such as 6DJ8s) is prone to oscillation at some very high frequencies unless care is taken in the design. This opens them up to microphonics associated with the parasitics. Its a nic... | |
| Will I benefit from a subwoofer with 20Hz speakers? There is very little musical content in that octave 20-40Hz and in my experience having too much bass becomes annoying after a while. @bishop148 The point is not more bass! The point is to get the bass right. If the bass is deficient, the ear ... | |
| Will I benefit from a subwoofer with 20Hz speakers? @dmilev73 My main speakers are flat to 20Hz. But at the listening chair I have a cancellation, so no bass at that location, while nearly everywhere else in the room the bass is fine. So I added a pair of Swarm subs. One is to my left, immediately... | |
| Digital amplifier fans, NAD C298 Purifi Eigentakt I wish Audiogon and other audio forums would have a subcategory of amplifiers dedicated to class D. There may well be reasons they do not break it down to that level, but trying to find information specific to D-amps requires a lot of winnowing d... | |
| Why do I need power management if I have a great power cord? Would love to see your system, or know what’s in it. Do you use power management in anyway? I don’t (but have a number of customers that do). My preamp employs heavy power supply regulation, which helps out immensely, and my amps employ over 35... | |
| Looking for warm tube preamp (should pair well with Pass power amp), budget $6000 If your amp has a balanced input, I think you'll find that it will sound better if the preamp is balanced also. If you go with balanced, there is a standard for balanced operation (and there's no standard for single-ended, FWIW...). This standard ... | |
| Why do I need power management if I have a great power cord? I've read that link several times in the past. BTW, I like your amps! The quote came from Nelson Pass. @piaudiol I've seen advertising, but not the actual quote (which IME is something very different!). Do you have a link? But tell me, ca... | |
| How much do voltage regulator tubes affect performance? I'm using General Electric vintage ones right now and it sounds good to me. Just wondering if their are "premium" voltage regulator OD3 or Od3a tubes available. Or if it even matters that much. It shouldn't make any difference at all unless t... |
