| Your journey with lower-watt tube amps -- Can a kit be good enough? Yes this Marantz 8B sounded more clear then McIntosh MC30. But despite Marantz bass wasn’t bad, MC30 bass was on the other league. It was also a big difference in complex music reproduction. 8B was good on very simple music but the sound became m... | |
| I'm new to Step Up Transformers @rmcfee SUTs require proper care and feeding if you want the best out of them. Transformers transform impedance. So the output impedance is a function of the turns ratio and the source impedance (the cartridge and cables). If the SUT is insuffic... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? Didn't have any particular issue with the amp, just blah, lack of transparency, resolution. This compared to two 845 SET amps I was running in that time frame. @sns The Merlins are not a good match for any SET unless you are using them in a sm... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @decooney , @hilde45 , One weakness of that amp is seen in the schematic. The 4 power tubes share a single resistor (bypassed by a capacitor) to set up the bias of the output tubes. There really should be a resistor and cap for each output tube p... | |
| Pass....Accuphase....or...... @southofdallas I've recorded stuff in the same halls I've played in. You get a sense of the hall and I wanted that in the recording. Each hall has a different sound to it so I describe that as the ambient signature. So yes, the ability to express ... | |
| Pass....Accuphase....or...... @southofdallas Thanks! I don't know that hall but I've played in a number of them here in Minnesota (bass in several orchestras so O'Shaughnessy, Orchestra Hall and the Ordway). I know what you're talking about but I'd never have thought to cal... | |
| Pass....Accuphase....or...... @southofdallas This is exactly why its a good idea to use speakers that are easy to drive. You don't have to sacrifice any resolution to have easy to drive speakers. Lower efficiency speakers tend to have something called 'thermal compression' whi... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 Nice! I'll be interested to hear your comments. I saw that amp on ebay as well and really had to think about buying it just so I could see how far I could push it. | |
| Pass....Accuphase....or...... It’s not so much high volume I’m after but dynamics. @southofdallas Proper ’dynamics’ should arise from the signal and nothing else. Quite often amps can generate higher ordered harmonics which the uses to sense sound pressure, so just as often... | |
| Would I be wasting my money to get a turntable? @audiotroy That is irrelevant. You still want to give it the best signal you can. | |
| Who positions their speakers straight ahead (zero tow in) and why. I can't immediately which ones, but there are speakers on the market with rising high frequencies, that are too bright when toed in, but sound great when toed out. @simonmoon With such speakers, to avoid side wall reflections which contribute ... | |
| Pass....Accuphase....or...... @southofdallas Something to consider: In most rooms if you need more than 100 Watts to make the speaker fly, the speaker is likely impractical. This is for the simple fact that, to make the speaker sound twice as loud you'll need 10x more power; i... | |
| Question about high current amps versus "not high current amps" @tomrk I offered a good metric earlier; whether or not the amp can double power from 4 to 2 Ohms. | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @sns To be clear, the Klipschorn rolls off sharply below 45 Hz. The older Klipschorns are not designed to be driven by an amplifier that has a low output impedance like an ST70. You'll know if your speakers are like this (the Klipschorn has been ... | |
| Would I be wasting my money to get a turntable? @fritzenheimer Master tapes from the 1950s, 1960s, 1970s and into the 80s have all degraded. Some are lost. So if you want to hear any recordings from this era and want to hear them at their best, you use a turntable and get LP pressings as origin... |
