| 300b lovers With use of RC cathode bias won't have such issue but we need to watch out when using fixed bias. @kmtang When setting the bias for any fixed bias amplifier, its good practice to check the bias after an hour of operation. IOW all power tubes re... | |
| It's a Long-shot: Meridian G02 conversion to balanced tape out @jji666 If you use the tape outputs in this manner, you will want to know that they won’t drive the inputs of a studio tape machine such as a Studer or Otari. Inputs like most studio machines use are ’+4dBm’ which is 1.23V into 600 Ohms- the main ... | |
| SUT help From answers to my original questions, it seems like finding a SUT with 1:10 and 1:20 options might be best since it sounds like there's been success with both and either should work with various configurations on my phono pre-amp. @mmcgill829 ... | |
| Need a modern Class A monoblock, preferably half or compact chassis atmasphere, name or show me a link for three to consider, I am not against the technology but so far none really seem worthy to pursue. I did contact one mfg. recently on their brand new product... no response @sayas If you want something that... | |
| Need a modern Class A monoblock, preferably half or compact chassis @sayas Why do you want class A? If its for sound quality, there are class D amps now that are every bit the equal of class A. | |
| New expensive power cord for amp and no change in sound? Not buying it. The voltage drop across a few feet of power cable can't be more than a volt. This is insignificant compared to the normal variability of the supply fluctuations between 114 and 126 VAC. @noromance I've measured over 2 Volts, but ... | |
| Could Class D really be that good? @asctim I can't seem to convince that guy that what he's saying about me is wrong. 🙄 @ricevs This is not a discovery. Those that have listened, have known this since audio reproduction and measureing equipment were invented. Most things that mak... | |
| Solid state amp vs tube amps @marquis4099 The differences you usually hear have to do with how tubes and traditional class A or AB solid state amps make distortion. Quite literally the 'sonic signature' of any amp is its 'distortion signature'. I used the word 'traditional'... | |
| Could Class D really be that good? You just stated above that any modern op amp has no sound (will not change the sound). @ricevs The above statement is false. Here is what I actually said: Not to put too fine a point on it, but when you can change an opamp (if its modern, ... | |
| New expensive power cord for amp and no change in sound? @roxy1927 The reason you can hear changes with power cords has to do with the AC line Voltage drop across the cord. More expensive cables tend to have less Voltage drop. But how much this affects various bits of equipment is a different matter. S... | |
| Could Class D really be that good? Wow, you just stated that all modern op amps are perfect. Uh, no, I didn't. This sort of comment on your part is known as a Strawman; its a logical fallacy and false by definition. | |
| Could Class D really be that good? People all over the world have changed those op amps and get different sound.....You, however claim that in a low gain circuit that all op amps have no sound. You are again a minority of one here.....thousands of audiophiles and manufacturers wou... | |
| Could Class D really be that good? NAD’s Director of Technology, Greg Stidsen, had this to say: “Like all amplifier classes, there are advantages and disadvantages to class-D. What is attractive about class-D is its relative efficiency and freedom from the vagaries of parts quali... | |
| Decware Sarah 300B Amp? @tksteingraber Sure! The Dynaco ST35 is a very nice circuit design. The amp at the link is new and a kit. But Dynaco made this amp decades ago and so vintage units can be found; if properly refurbished they'll give any SET a run for the money. Dy... | |
| Decware Sarah 300B Amp? @bluethinker Why do you want an SET? There are Push-pull class A amps that are just as musical and involving, if not more so. Almost any of them would have wider bandwidth at either end of the spectrum. |
