Should Amps be plugged into a power conditioner? Current limiting starts at the power cord. Any time you have a glorified power strip, like so many so-called 'power conditioners' seen marketed to the high end audio community, the power cord it uses will have a voltage drop. We recommend to our ... | |
300b lovers @alexberger , @lynn_olson mentioned earlier: Ralph brings up a very good point about feedback: the underlying theory assumes a distortionless summing point. (The summing point is the comparator input between signal input and the sampled output.)... | |
Help with XLR ICs. does that translate to: if the equipment is truly balanced, then the XLR interconnects do not make a difference, but if the equipment isn't balanced but instead just has XLR but is really single-ended, then the XLR cables matter similarly to sing... | |
Help with XLR ICs. This is a serious question, not intended as a flame: can someone please explain to me, given the topology and function of balanced circuits, how any particular XLR cable composition can make a significant difference in sound, since whatever influ... | |
Are Bruce Moore "Companion" and MFA "Magus" similar products? MFA was prior to Bruce being on his own. Looks like the two are very similar in scope. | |
300b lovers In my next phonostage I want to make an external power supply with a separate filament transformer. But I haven't decided which RIAA schematics to use. There are basically two types of tube phonostages. In one type RIAA is implemented in feedback... | |
300b lovers Sounds like @atmasphere is early on their journey with a PP 300b. Certainly far enough along to demonstrate a prototype at a show, much as we did in Seattle last summer. We started prototyping with DHTs seriously about 20 years ago. Back in t... | |
Handling Heavy Amps @elliottbnewcombjr The FDA has approved a prosthetic meniscus replacement now so knee replacement doesn't have to be a thing. Thought you should know; I apologize if you already did. Good Luck with it! | |
Looking for 50-100 watts of Tube Power (give or take) for my JBL 4349s I’m open to the idea, but I use to run a Decware CSP2+ in front of an Odyssey Khartago, and I don’t remember this combo having the soundstaging of a good tube amp. @rischa There are now some solid state amps (class D even) that cast a sound sta... | |
How important is the efficiency of a speaker to you? Btw, I remember listened 4-5 times in the past the original Wilson Watt and this is a fantastic true monitor not high efficiency as a horn but measured 91db and this Watt has a problem for any amplifier ( tubes forbidden with ) at 1khz its impeda... | |
300b lovers Wow, is that the first Atma-Sphere with an output transformer? No, nor the first to be shown in public or sold. We make a small 5Watt/channel integrated amplifier that is suitable for desktop, bedroom, headphones or a main system if your speake... | |
Handling Heavy Amps My dilemma now is that while I really enjoyed this sound presentation it wasn’t significantly better to my ears than the Bryston that would justify twice the price So I will struggle with this decision If it was around $9 or $10k instead of $14... | |
Handling Heavy Amps @cundare2 If you don't mind some correction, the 3rd harmonic isn't 'nasty'. Musically its an octave and a 5th above the fundamental tone. Its well-known that it is innocuous such that this fact is often only mentioned in passing in engineering to... | |
300b lovers Ralph, I see you introduced a PP 300B amplifier at one of the recent hifi shows. How do you think it compares to your Class D amplifier, in subjective terms? The prototypes at the show sound very similar to our class D amps; the big difference ... | |
Handling Heavy Amps Technical papers that discuss Class D topology suggest that the distortion resulting from the topology’s dead-time constraints is similar in effect to what we used to call TIM or SID distortion in high-feedback, low slew-rate designs. @cundare2... |
