| Technics SL-1200 vs. Scoutmaster So, before I drop a bunch of cash on a new arm, what would I notice going to a 1200? I've heard they're not quite as inky black quiet as the VPI, and not quite as much low-end. Any truth to that? @mezz955 If you're talking about the Technics ... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 If you install that update I mentioned about a separate cathode resistor and cathode bypass capacitor for each channel, the cathode resistor value is 190 Ohms. I recommend a 5 Watt part so it will run cool. The bypass cap is then 50uf. Th... | |
| Phono Cartridge IMD Measurements, Observations and a Question Left unexplaind is why I can't alter the IMD very much. @kevemaher The platter pad is a variable common to both arms and cartridges. When the platter pad is doing its job properly, if the volume is all the way down and with your head close t... | |
| Class A\B or D for summer months (vs Class A) You can't beat.a class A for room heating during the winter! @fatdaddy2 Here in Minnesota even a class A high powered triode amp has no dent on the room temperature... | |
| Class A\B or D for summer months (vs Class A) @tbac23 I listen to a class D amp year round. I'd put it up against any Pass Labs amp with no worries. It replaced a set of class A tube monoblocks and I've not had any reason to look back. But you might also consider that if your amp makes heat ... | |
| Phono Cartridge IMD Measurements, Observations and a Question @kevemaher You might get a little device called an inverse RIAA filter to put at the output of your CD player. If you can reduce the level properly, you could test the phono section too. The one at the link provides some attenuation. | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 I'd go with a set of JJ EL84s before Sovteks or for that matter any Russian made version. Have the tubes been tested? If any are bad all bets are off. If you have level controls on your speakers it might be a good idea to run pink noise... | |
| Need a modern Class A monoblock, preferably half or compact chassis Do you have any future plans to show your Class D amps paired up with speakers a bit larger and more demanding than Fritz' little gems? @decooney We showed with the Caladan open baffle speakers at AXPONA last year. We're not sure what the next ... | |
| Pass....Accuphase....or...... @southofdallas Where do you live? Our class D isn't the only you might consider, FWIW. | |
| I'm new to Step Up Transformers In fact many people do not know that proper loading is usually done from a selector switch on the phonostage in which the switch run through a series of resistors. Someone looking to have there preamp get the proper load for their cartridge is a ... | |
| Pass XP-17 and Hana ML loading question Same here. I've had the cartridge several years and really can't complain. Its effortless with everything I throw at it. | |
| Pass....Accuphase....or...... If I understand it correctly: the Accuphase class-A is a push-pull amp, the same as PASS LABS. Do they leave class-A at some level? How much class-A power does the A-48 deliver before drifting into AB? @southofdallas This isn't a concern. If a ... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @bruce19 There's a kind of ceramic cap called an 'NP0' (for Negative Positive Zero) which can sound surprisingly good. They are available with leads and in the value you need, are about the size of a small bead. By ceramic cap standards they are e... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @bruce19 You could install a coupling capacitor between the source (perhaps a preamp) and the SET, with a value calculated to have a -3dB point at the desired crossover frequency. Frequency in Hz = 1,000,000/Capacitance in uF times Resistance on... | |
| Phono Cartridge IMD Measurements, Observations and a Question @kevemaher You’ve not ruled out RFI sensitivity on the part of the Musical Surroundings preamp, which you don’t seem to mention in your list just above. RFI issues can produce quite a lot of IMD. By 'stuff upstream' I meant the arm mounts, arms, ... |
