| 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... | |
| CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS Do they benefit from power conditioners and power cords? Its able to reject a fair amount of AC power line problems. A nice power cord if helpful if you push the amp hard. Its only going to draw serious power when its making power (true of all ... | |
| Let me end the Premp/Amplifier sound debate ... I thought "a straight wire with gain" is unachievable currently but would be the most desirable scenario for ultimately the best possible sound. It isn't. An amplifier often has to behave as a voltage source, since most speakers are meant to b... | |
| Why do I need power management if I have a great power cord? A Class A PASS XS300 monoblock will dump 48A on demand. You need two of these. See where this is going? @piaudiol This seems really unlikely!! Giving the amp the benefit of the doubt, and assuming it can double power into 2 Ohms, it would... | |
| CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS do they need break-in? And if so, then how much? It appears that they do from the feedback we've been getting. Apparently 100 hours or so. | |
| Why do I need power management if I have a great power cord? @atmasphere do you have experience with your amps benefiting from using the two example of power conditioning units that you mentioned? Yes. @atmasphere great discussion of these two power conditioners. I wonder 2 things: 1. How much load... | |
| Why do I need power management if I have a great power cord? I guess, what I wonder, is if some “power conditioning” devices still may add value. If passive devices, it can, and will be marginal. I’m going to research more into the 240 V option that makes sense. Does anybody else know anything about t... |
