| Concerningly loud pops in vinyl playback Tubes in the ARC Ref 6 going bad. Maybe PSU tubes? But it really seems to be instigated by a volume level on the Ref 6 going above 40. @mulveling If this only happens when the volume is turned up then the turntable and phono section are off the... | |
| Atma-Sphere Class D… Amazing @fredag 100W with 8Ω, 200 with 4Ω. Current limit protection will kick in with lower impedance loads- as long as not to full power the amp will double its output power, but will reach its protection limit at about 250 Watts. | |
| Discuss The Viv Lab Rigid Arm Exactly, and that has been my point in this thread. To make real progress, we need to correlate measurements with what we hear. @cleeds Its been my experience that's what you do to sort out what's going on. That is what led me to increasing ri... | |
| Discuss The Viv Lab Rigid Arm I understand the mathematic fundamentals behind digital audio, for example (Fourier, Shannon/Nyquist), yet intuitively it still seems impossible to me. Like any technology digital had an uphill path to follow. For example jitter was a thing kno... | |
| Speakers for Atma Sphere M60 mk3 @fredag Your room is a bit on the larger side. If I were you I'd be wanting to see if an audition could be arranged. | |
| Speakers for Atma Sphere M60 mk3 @fredag How much power are you running right now? | |
| Speakers for Atma Sphere M60 mk3 @fredag For the M-60s I would use speakers that are at least 8 Ohms and 91 or higher efficiency. With any amplifier, tube or solid state, its beneficial for the speaker to be easier to driver rather than harder; this will always result in less di... | |
| Discuss The Viv Lab Rigid Arm With diffusion panels directly behind the speaker is it possible to shorten that 5 foot distance by a small amount? @neonknight No. But if the speakers are closer than the 5 feet having something absorptive might help with the harshness that w... | |
| Discuss The Viv Lab Rigid Arm What about the phase anomalies you and I happily live with, caused by dipole speakers where the rear radiation is 180 degrees out of phase with the front? @lewm @mijostyn The reason any speaker with rear firing information should be at least 5 ... | |
| Speakers for Atma Sphere M60 mk3 The problem is that many can fix the amps but they do not have access to parts from Harman. Now: can I buy parts from YOU, IF needed? Living in the frozen north is a pain....specially without music ;) @fredag I get that- we live in the frozen ... | |
| Speakers for Atma Sphere M60 mk3 @fredag Somehow we've managed to keep our products alive in Europe :) We've been exporting to Europe for the last 33 years. They about built to last and also to be easily serviced. | |
| Discuss The Viv Lab Rigid Arm Thinking you are going to have a setup that won't mistrack is akin to planning on getting into the ring and not getting hit. You expect trouble when designed analog equipment! It is for that reason- vibration (whether from the LP, airborne or o... | |
| Discuss The Viv Lab Rigid Arm WRT cutting level and mistracking, it seems there is not a good definition of what mistracking actually is. My take is any movement in a direction not cut on the record is mistracking which means it is constant occurrence from numerous causes. ... | |
| Speakers for Atma Sphere M60 mk3 The SF is a 4 Ohm load, rated 91 dB Sensitivity. To convert to Efficiency, which is a more useful spec for tube amplifiers, you have to subtract 3dB on account of the fact that Sensitivity is a voltage measurement, while Efficiency is power. 2.83 ... | |
| Discuss The Viv Lab Rigid Arm The problem with the ’mechanical engineering’ view is when you define a "goal" or a "standard" then it can easily be seen if that goal is met and an unassailable judgement made. No consideration is given to the absolute magnitude or the underlyin... |
