| Lowering Tube power amp output @tubelvr1 The more powerful you make a tube amp (unless its an OTL) the more limited its bandwidth becomes, due to the output transformer. What this means is that for the most part smaller tube amps sound better (except for OTLs where bigger ones... | |
| Looking for a preamp with XLR connections We've been doing balanced line preamps for home audio longer than anyone else. We did it because if you support the balanced line standard, you can get off of the interconnect cable game and not have to worry about their 'sound'. It didn't occur ... | |
| MoFi controversy I made the same mistake FWIW... | |
| Class D amplifier with TPA 3250 board As long as you don't push them too hard, it can be a bit surprising how good many of these little amps can actually sound. Of course then you start to wonder how good it can get... In our own work on class D amps (we have a design entirely our own... | |
| MoFi controversy @blisshifi I'm sure they work fine! As with all things, so much in digital depends on execution. I would not expect any greater dynamic range if you are dealing with sources that use compression to begin with. But you might have greater resolution. | |
| MoFi controversy Anyway, it seems like one of their advantages is process, apart from custom made Tim de Paravicini analog paths (probably preamps, amps and modifications to the lathe?). They are able to cut an acetate, have it plated and pressed and listen to it... | |
| MoFi controversy The rep also stated that they would even occasionally go to the trouble of ’baking’ the master to improve the transfer ( which at the time i thought as odd). @daveyf Baking the tape is done to chase water molecules out of the polyester tape bac... | |
| Class D amplifier with TPA 3250 board As far at the argument that an amp was tested and it was 10 percent distortion??? @timlub That came from the specs published by the manufacturer of the chips: TA2024 10% at full power (10W) TA2020 10% at full power (13W) TA2022 10% at full p... | |
| MoFi controversy Most lathes preview the a digital file which allows the lathe to cut within its safe parameters. All analog cuts that turn out great might be "minor miracles". I'm sure @atmasphere can explain the preview process better. The preview process i... | |
| MoFi controversy FWIW dept: I ran an LP mastering operation for about 10 years. LPs get mastered from digital source files all the time. The trick is to make sure that the file you're working with does not contain the DSP stuff that the digital release file does.... | |
| Anyone Know Where To Get The 4 Big Can Caps? @arianabonsai Mouser Electronics No-one makes 67,000uF anymore. 68,000 is the standard value and easy to find. The amp won’t have any problems with this. You may notice the new parts are smaller- that’s normal. Be careful to order the correct d... | |
| Why do hipsters prefer analog? Stuff's really hip man, super cool 😎 | |
| Good cassette player? Seems I want one with their discreet heads, but simple internals. The ones with three heads have a way of the record head failing. The head is rare and expensive (+$300). So if you are looking at such a machine, make sure it records on both cha... | |
| Paper cone drivers/natural materials The midrange of my loudspeakers uses a beryllium dome diaphragm and has no breakups in the audio passband. Beryllium is an element and thus natural. Paper is man-made so isn't :) Guitar speakers use paper because it breaks up in a certain fashion ... | |
| Phono stage options - balanced with XLR both input and output... I agree with lewm that cartridges are not inherently balanced (only 2 terminals) @hagtech A balanced source will not have a center tap. This is because a center tap will decrease the Common Mode Rejection Ratio (CMRR) on account of the fact tha... |
