| Does a turntable mat make any difference? It does. But the one you got probably doesn't do its job. A lot of mats are intended for DJ 'scratching'. For home hifi, the pad has two jobs: damp the platter from ringing and damp the vinyl from any resonance. If the platter pad is doing its j... | |
| Good Speakers for Rock and Roll Under 15K I don't think you are going to be in a room and picturing where the lead guitar is vs the bass guitar. @willgolf This suggests to me that you've not heard every rock recording out there. I run a studio; we pay attention to where we place instr... | |
| Harman Kardon A300 @ccogopher 'upstream from the power supply' means the AC power switch and power cord, so I'm thinking you meant something else. The power supply is shared by both channels. So I think the power supply is OK. Since you have a schematic, check the... | |
| Eliminated my preamp with amazing results @arhgef There are plenty of switches that can do the job. | |
| 2a3 ? SETs have a limitation of the greater the power, the less bandwidth is obtained from the output transformer. 7 Watts (300b) is a practical upper limit to what can be considered 'hifi' bandwidth. The 2A3, being good for about 4 Watts, allows the de... | |
| Good Speakers for Rock and Roll Under 15K @gregjacob Its actually a myth that a speaker can be good for one genre of music (rock) and not another. If your speakers aren't good for rock, then they are likely weak with jazz and classical too. Put another way, no-one has ever figured out a w... | |
| Best Vintage tube amp / preamp manufacturer @koh_i_noor If you like the old ARC stuff (like the SP-3) then if you can find an H/K Citation 1 and have it refurbished you're in for a pleasant surprise. The weak bit about the Citation was its connectors (which were the only game out there at t... | |
| Harman Kardon A300 @ccogopher Before you go to a tech you might compare the working channel against the bad one. I hope you have a schematic!! Have you been able to sort out if the weak channel is in the power amp section? Or does it occur further upstream? Do th... | |
| XLR to RCA conversion the specific model he recommended isn’t available. That’s why I posted. He recommended the Jensen PI-2XR. @hifinut51 I know someone that bought that exact ISOMAX unit only 2 weeks ago. Did you talk to anyone at Jensen? | |
| Using PA Speakers In A Home "Audiophile" Application! @ditusa Its worth noting that my drivers use a beryllium diaphragm (as you probably already surmised); the driver is also modified to run a field coil. As far as I'm concerned, JBL knows what they are doing with their horn structures- I've seen no... | |
| Analogue clipping from digital sources but phono stages have additional gain just for them. It's true that you almost don't need any gain for CD's, but tape decks and tuners were often near that, no? @erik_squires No. quite often a tuner or phono section will make 1Volt. A cassett... | |
| Analogue clipping from digital sources Also, Ralph is right for an AMP, 2V might be overload but preamps have been 100% aware of the CD standard since then and are built for it, so I disagree. @erik_squires FWIW the high output digital problem is one of the issues that any preamp ma... | |
| Using PA Speakers In A Home "Audiophile" Application! @ditusa Its similar to this one. The horn was installed in 1998 FWIW. | |
| Eliminated my preamp with amazing results The other issue I'm struggling with is why are manufacturers adding all this gain? The DAC adds gain then goes to the preamp that has more gain and now you can't get the volume knob up over 9 o'clock. I don't see any reason that streaming music n... | |
| Using PA Speakers In A Home "Audiophile" Application! That’s not much of a basis for qualified comparison here. Which JBL’s are those, and how are they (or the Altec’s) representative of a whole segment of speakers? Look, I believe we’ve been here before, but there’s nothing to support the narrativ... |
