| Discontinued equipment that you wish were still here. What do you miss or think will miss? The FR MC201 was a really nice sounding cartridge! Favorably reviewed in IAR. Wish I still had It! | |
| Discontinued equipment that you wish were still here. What do you miss or think will miss? @grsz06: I have a GAS Thoebe preamp and a Quatre Gain Cell amp in my collection! Both worthy of resurrection! And I owned the FR MC201 in the long-ago past! | |
| Why do amps sound different? I have some SE amps: 2A3, 45, 6BG6. They do sound nice in use with my Heresy's! | |
| Why do amps sound different? @atmasphere Paul Klipsch opined that what the World needs is a good 5 watt amp! Along with his K-Horns, of course! I believe he favored the Brook 2A3 PP amps! | |
| Why do amps sound different? The speaker is THE overwhelming influence on SQ - NOT the amp, preamp, DAC, interconnect, speaker wire, fuse ... | |
| Why do amps sound different? Most electronics (amps, preamps, DACs) have been essentially sounding alike for the last 20+ years! Contrary to what the "golden ear" crowd claims! The marketplace dictates good sound and weeds out poor designs (except for some tube gear!). You wa... | |
| Why do amps sound different? @path73 John Otvos did that with his Waveform speaker. He used a custom-made three-way active x-over made by Bryston and three Bryston stereo amps (one per driver). No internal passive x-overs! Excellent SQ! And this was 30+ years ago! Now apparen... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Ohm's Law rules the amp/speaker interaction! And I agree with you that DF need not be excessively high to have adequate results! | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. I read a report by JA measuring a Prima Luna tube amp (some years ago). He found an output impedance of 8 ohms! This means a DF of 1 ohm or less! Combined with the typical varying impedance of most speakers this is way too high! How can supposedly... | |
| DAC's : The missing feature: Signal quality Even the first-generation CD players had jitter levels below 1 nanosecond! What they didn't have (in the first year or two) was full 16-bit capability. Typically 14-15 bits, due to DAC-chip (ladder-type) architecture. This only reduced noise-floor... | |
| DAC's : The missing feature: Signal quality Jitter below 1 nanosecond is inaudible and not a problem with any of today's CD players/DACs. Regardless of what the "golden ear" crowd claims! And asynchronous DACs (with their re-clocking of the input signal) eliminate jitter (uncertainty of the... | |
| Setting up 2 power amplifiers to setup at once help? Again, to passive bi-amp (bi-wire) each speaker needs two pairs of connectors (with jumpers) on the back. This allows separation of the internal x-over into low and mid-high frequencies. I doubt the RTi A7's have this! | |
| Setting up 2 power amplifiers to setup at once help? Want to hear a "different" sound from your speakers? Get a tube amp with high output impedance (over 1 ohm). Like a Prima Luna (output impedance of 8 ohms!). Or a single-end tube amp (low power and 3%+ distortion!). | |
| Setting up 2 power amplifiers to setup at once help? I doubt that you will be able to hear any qualitative difference between the sound of the Denon vs. the Yamaha. All modern electronics have been pretty much sonically equivalent for the past 20+ years or so! Regardless of what the "golden ear" cro... | |
| Setting up 2 power amplifiers to setup at once help? I have bi-amped two pairs of speakers successfully using an active crossover. Splitting the signal into bass and mid-high frequencies. One pair of speakers for bass, one pair for mids and highs.The active x-over allowed for gain adjustments for th... |
