| 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... | |
| Using PA Speakers In A Home "Audiophile" Application! Modern pro drivers (and even ones decades old) are extremely well designed, and used within their design parameters - not least actively - will yield no effective problems with breakup modes. @phusis I've run into breakups in older designs (like... | |
| Using PA Speakers In A Home "Audiophile" Application! @deep_333 You will need a low noise amp for that and also one that has low gain, otherwise the noise floor of the amp won't be much help. The Benchmark, while excellent, as over 30dB which means you'll notice noise from your front end. Our class ... | |
| Using PA Speakers In A Home "Audiophile" Application! @deep_333 My concern would be breakups in the drivers, which cause distortion and harshness. PA stuff mostly does not care about that sort of thing since sound pressure is the main goal. But its a big deal with home audio speakers, where such thin... | |
| surprising comparison of tube preamps So is your point leading to any reason to believe that integrated units have an advantage? Any, or would they need to be fully balanced from input to output? @akgwhiz To the first, perhaps; integrated amps do have the advantage that a passive... |
