| Phono Stage - The great analog tragedy Is this a "what is the best phono stage" thread or is it a debate on very vintage vs less vintage (because a 25 year old phono stage design does not fit the conventional notion of "new", not that there is anything wrong with that) vs really new? | |
| Are you operating in the correct SPL window for high-fidelity listening? To refer to a "volume pot" as an "attenuator" does not necessarily per se make it better. A rose by any other name, so to speak. Yes, some analog attenuators are better than others. Upgrading the attenuator is often a very effective way of making ... | |
| Are you operating in the correct SPL window for high-fidelity listening? The gap between 70 and 85 db SPL is huge, which speaks to my point that we have no agreed upon standard for measurement in the first place. So discussing in terms of SPL is meaningless. | |
| Are you operating in the correct SPL window for high-fidelity listening? First, the problem is how you measure SPLs. The measurement will vary greatly according to how you aim the sensing microphone and what type of speaker you are measuring. For example, planar (either electrostatic or electromagnetic) speakers are ... | |
| Turntable Setup Consultant What gives you the feeling that your TT or TTs is/are not properly set up? Did you do the original alignments yourself? With what tools? Thanks. I ask because I think one can obsess needlessly over what is inherently an imprecise procedure. | |
| Will a record weight harm the motor in a direct drive turntable? I own an AT618A that I purchased in Tokyo on one of our visits. (Sometimes I just buy stuff I don't really need only because I am there and it costs less.) It weighs 600g, or more than a pound. I use it only on my SP10 Mk3, which has a 21 lb plat... | |
| Will a record weight harm the motor in a direct drive turntable? Hope the responses take a load off your mind. Like someone else said, it’s not the motor but the bearing that might be negatively affected over time. And of course it depends on how much weight. I was surprised at some of the conservative response... | |
| Phono Stage - The great analog tragedy I have no dog in the fight, but some would argue that it takes some circuitry to make playback using a strain gauge conform to the RIAA pre-emphasis that is built into every LP during the production process. In other words, without some filtering... | |
| Phono Stage - The great analog tragedy Arnieco, your thesis is the opposite of Pani's. Any phono stage requires lots of gain, more than any other audio component, and a filter that conforms to the RIAA standard de-emphasis curve. Except for tubes, today's parts (discrete transistors,... | |
| Phono Stage - The great analog tragedy I think your experience must be limited, and I disagree with your premise. Not to say those vintage units were better than what we have now, but only to say you might be surprised at the similarities between old and new circuit designs. We simply ... | |
| Phono Stage - The great analog tragedy What Dover said. I can give you some "obvious" advantages of a full function preamplifier vs separate line and phono stages. Provided you allow for the luxury of an outboard PS for the full function preamp, I would argue that is the inherently su... | |
| Phono Stage - The great analog tragedy The fact that most audiophiles used a "full function" preamplifier back in the 60s, 70s, and even into the 80s, rather than a dedicated phono stage does not in my book mean that phono was taken for granted or given the short end of the stick. In f... | |
| Phono Stage - The great analog tragedy The reason "NFB" goes hand in hand with "active" gain in a phono stage is that by implementing NFB there is an inevitable loss of overall gain. (With NFB, some of the voltage output of the stage is reverted back to the input or some earlier stage ... | |
| Where's Mijo? Yes, he’s a dust cover down/ idler hater/ digital room corrector but fun to argue with. | |
| Phono Stage - The great analog tragedy Leben is free to invent jargon but a phono stage with NFB uses C and R to effect the NFB. Hence it’s still a “CR” phono stage. But now I see where you got your idea. Like Dover said, you can also implement RIAA using inductors, plus R and C. There... |
