| Speakers 10 years old or older that can compete with todays best, Sound Lab ELS | |
| REF5SE tubes If you haven't, I'd suggest changing the 6550 if it is that old. If / when it goes it can take out other components in the PS. 3000 hours is the recommended time to replace, I believe, | |
| Any (new) Tube Testers that can be recommended? And the Amplitrex can test output tubes at realistic voltages (example 6550a tube at 250V, 450V or 500V vs 170V w/Hickok 539b, plus the Amplitrex can test 6H30 and KT-150 tubes. Also, Amplitrex can test at a "fixed" bias or "auto" bias...Matching... | |
| Where did the term "mono block" originate? Why isn't or when is a stereo amplifier a "stereo block"? | |
| Amplifier circuitry-4 ohm vs 8 ohm I have ARC amps from 1995, 2018 and 2023, and they all have 16, 8 and 4 ohm taps. My ELS speakers impedance curve indicates about 30 ohms at 20Hz and 3 ohms at 20kHz. The 16 ohm taps sound excellent. The 8 ohm taps do too, but with a different bal... | |
| Can’t buy output tubes anywhere except from manufacturers at high prices. FYI: B&H sells "Telefunken" tubes but they are not German made Telefunken tubes. | |
| Why are People Dumping their Audio Research Gear and What Does it Say about them? After turning on the REF6SE I have to decide whether to fire up the pair of VT-150 SEs (1995, GE6550s, Telefunken E88CCs) or the pair of REF160M MKIIs (2023 KT150s, 6H30s). Both designs have spectacular sound quality. Both very well built. For m... | |
| Acoustic Signature turntables Rumor has it the Levinson 5105 TT/Arm is an Acoustic Signature manufactured in Germany system. | |
| Can a Amp be "timeless" and compete with todays amps? I’ve tried the three options and 8 is the one (and only one) with both amps on the Soundlabs, also what Soundlabs states. Both amps sound excellent dynamically with a subtle tonal balance difference. 6550 vs KT150 and 1995 vs 2017 or so. | |
| Can a Amp be "timeless" and compete with todays amps? I was reading through this thread and decided to post here what I had posted not too long ago on the SoundLab Owners Forum: Audio Research VT-150SE mono amplifiers (1994) vs. Audio Research Reference 150SE stereo amplifier (2016). "I recently pu... | |
| A full range speaker? Musicians performing in a room, captured with a "stereo" microphone (Blumlein)...Playback: If you filter 35Hz and lower......you take away much of the "room" (the acoustical space) that the recording did capture and is capable of presenting back t... |
