| Good Entry-Level DAC We just got in a Topping E30, which apparently replaced the D-30. It measures well and sounds better- smoother and more 3D than the D30; Already we've seen it topple a $4000 DAC... I've no doubt that it would help out an entry level NAD. I've neve... | |
| Is there a Solid State amp that can satisfy a SET guy? The posts caught my attention as I am in the middle of choosing a 211 or 845 amp. You’ve allayed the concerns the posts raised.@atmasphere Can you comment as well? Thanks.@david_ten The bigger the SET, the more issues you have with bandwidth. So... | |
| phono/preamp analog front end Here's something to keep in mind. Loading of low output moving coil cartridges is not for the cartridge- its for the preamp, but only if the preamp has problems with RFI. Cartridges generate RFI because they have inductance, which is in parallel w... | |
| Best tube preamplifier for under $15k @haabitat Get a balanced tube preamp for your amp. If you get one that supports the balanced line standard then you will have a fair amount of immunity to the sound of the interconnect cables. FWIW most balanced line products in high end audio don... | |
| The Carver Amp Challenge and the 21st Century and it's Failure Not moot, contradictory, and kind of goes with some of the subtle things I've heard with cables, that the sound of an amp is much more affected by the impedance changes in a cable than we have thought up until now. Sorry, this should have been i... | |
| The Carver Amp Challenge and the 21st Century and it's Failure I guess I don't understand this comment.Distortion is why tube amps sound warm and smooth (some lower harmonics and not so much higher orders) while transistor amps sound brighter and harder (not much lower orders but what higher orders exist are ... | |
| The Carver Amp Challenge and the 21st Century and it's Failure Using the complex impedance of the speaker in between two amps is how it happened. Amp1 (+) =====> (+) Speaker (-) =====> (+) Amp2The goal being to null the voltage at the speaker terminals with music, which, as you allude to, could only h... | |
| The Carver Amp Challenge and the 21st Century and it's Failure And since distortion is one of the main things that we audiophiles hear as differences between amps, it would seem that the Carver approach is moot. | |
| The Carver Amp Challenge and the 21st Century and it's Failure One vast, gaping hole in Bob's idea way back then is the output impedance of the two amps involved in the test. If not identical, the one with the lower output impedance will dominate the results. And if its not obvious, another serious issue is s... | |
| Expanding questions about tubes in a preamp Getting rid of microphonic tubes is far more important than damping rings. They have a tiny effect by comparison. I would only use them if you already have decent tubes.Heat in tubes causes failure. The more damping rings and the like, the shorter... | |
| What Class D amps will drive a 2 ohm load You and Ralph are both just in product protection mode, it's so obviousActually, no. Again, I suggest you read the white papers of Bruno Putzeys and perhaps some of his interviews. Quite plainly, you have mistaken impressions about how class D amp... | |
| Really need some help finding a full range speaker I will add a third recommendation to look at the Audiokinesis Swarm subs; with them you will get good bass to 20Hz.The speaker you need to do 60Hz or so and up is then a fairly easy prospect as it does not need to be large! | |
| 2 different Bedini 150/150 Mk II Amps Are filter caps the same as power supply caps? Yes. It took a fair bit if disassembly to replace the larger caps. I suspect that varies from amp to amp though. | |
| Loudness - Why has the industry stopped producing amplifiers with this feature any longer? Yes, dusty, worn POTS and oxidized contacts on switches can be a problem. But that is why we have DeOxit ;-) DeOxit has a dicey reputation in this regard. Its not exactly the best medicine if you are dealing with a part that has the resistive ele... | |
| What Class D amps will drive a 2 ohm load The Mosfet output transistors themselves as well as the output filter, which both have not changed much since it’s inception. The GaN output transistors are maybe going to change that with optional far higher optional switching speed available, ... |
