·BTW, I have the rebuild book, "tu.be or not tu.be" and will nun off a copy at cost.
Nice. I also have a pair of open-back headphones. Mine are Sennheisers. What are yours? HMV?
These were open funnels to mimick the higher noise floor some mental illness produces in people and demonstrating how difficult it is to focus with so much noise in your head.
Highly recommended exhibition in the MoS in Cambridge.
Some Bose, mostly for long flights. Used in great shape. Case and adapter, I finding them indispensable for long flights. The proverbial night and day difference.
First pair bought after a flight from Chicago to Shanghai .. Lots of regulars were getting fed cocktails well before take off. By mid flight they were out of control. I had no down time up coming so I was NOT HAPPY. As soon as I got home, I bought em. Wore em out, bought another, wore them out and am on my third pair. Agree, they are mission critical for a frequent flyer.
Question for you folks... I’m not a techie sort of person so I don’t have a lot of understanding about how hi-fi actually works so maybe someone here can explain this thing that has long perplexed me.
Why do hi-fi components require different volume levels on my pre-amp volume knob? My CD plays at a much lower level than my turntable, and my streamer requires an even further twist of the knob. Why is this?
Thanks for enlightening me.
Depends on the output of each device and the specifications of the preamp in treating those signals. The output level of the various sources in your system; turntable, CD player, streamer are all different so the final output from the preamp will all be different, too for the same position of the volume knob. A turntable is a special item, the output of a moving magnet cartridge is usually in the 3 to 5 mV range (tiny!) so the phono stage in the preamp has to handle this and amplify it before sending it to the power amp. The lower the output of the cartridge the more you will have to turn the volume to achieve a given level of sound. Sounds like you have a cartridge that is higher on the voltage scale, hence you get a higher volume.
Does the streamer (I assume it's a streamer/ DAC) have an internal volume setting? Many can be directly connected to an amp, so they have internal volume control. When a preamp is in the chain the internal volume setting should be set to max/ 100%. CD players and DACs typically output around 2 volts (that is the standard) if single-ended outputs are used, so there should not be much difference between the CD player and streamer.
