| transformers/output impedance To clarify a few points made immediately above:Negative feedback has only a minor effect on high frequency bandwidth. This is because HF bandwidth is a function of the risetime (or slew rate) of the circuit, which will not be affected by bandwidth... | |
| Is a tube phono better than ss? Salectric, a lot has to do with how 'fast' the preamp is. If you have poor slewing rates that won't go well with active EQ IMO. I also find almost any preamp with active EQ to be a little brighter (my guess is due to odd ordered harmonics but if s... | |
| Thiel death do we part . . . Seems like the early Stones LPs are quite nice if you can find originals. Not much for stereo mix though. | |
| Class D and Power Cables Bifwynne, That was on a 100-watt tube amplifier. The 2-volt drop is bigger on the secondary side of the power transformer(s). If you think about it, the heaters cool off a little, the B+ is a little lower, the power tubes are not conducting as har... | |
| Is a tube phono better than ss? Pops and ticks as an indicator of NF Ringing?Hadn't thought about that but would seem to make sense. Seen it. about 25 years ago a friend of mine and I both bought the same UHQR LP from a specialty store. For some reason his was noisy and mine was... | |
| Class D and Power Cables Hi Al, I'm sure external wiring has effects. But we don't get to change that stuff very often, so we also don't get to see how it affects things. The power cable OTOH is something that is easily experienced, and I have been able to correlate audib... | |
| Class D and Power Cables Yes, power cables make a difference, maybe even more so for class D.If you want to know the theory:In a conventional power supply (transformer, rectifier, filter capacitors), once the filter caps are charged the amplifier circuit only draws their ... | |
| What does "voiced" mean to you? In amps and preamps it pretty well means the designer does not know what hes doing. | |
| TriPlanar Tips Right! In addition, I just barely loosen it so I can put the arm back in position, and then move the rest to to the right position. Then I tighten the screw back down. | |
| Thiel death do we part . . . Like I put in my post- many bad recordings have artifacts in them (distortion, excess high frequencies) that seem to exacerbate the problems in poor playback equipment.As many people that work in the recording industry know, if you have really goo... | |
| Thiel death do we part . . . I often use poor recordings to let me know if I am on the wrong track. Sure- excellent recordings should sound amazing. Its the poor ones that tell me whether the system is editorializing or not.I regard a lot of the editorial as possibly being ar... | |
| Is a tube phono better than ss? There is more to it than just tube noise. A tube phono section can be built to operate with zero negative feedback and passive equalization. There is an advantage to this- less audible ticks and pops from the LP surface.This is not because of less... | |
| Brinkmann Bardo and Tri-Planar VII-U armrest issue Hi Doug, I had a conversation with him about this yesterday. He maintains that when the arm is sent out, that the mount is installed according to a jig so that it is correct.The problem is that quite often the arm board, which is supplied by the t... | |
| Brinkmann Bardo and Tri-Planar VII-U armrest issue Tri is very aware of it- it is he that told me where to look in the first place. Funny its not in the manual though. I'll mention that next time we talk. | |
| Brinkmann Bardo and Tri-Planar VII-U armrest issue ^^ good idea- and done. |
