  1. You've just uncovered what few realize - the inherent bias in just about every professional and user review unless you know and account for the room's sonic signature which most don't. And probably the most important reason for subwoofers - to match the human ears' audible response curve.
  2. There is no linearity since we perceive different frequencies at different levels and at different levels the perceived loudness shifts. Check out the Equal Loudness curve. Nothing is easy :-) I use Sean Olive's listening curve as a good baseline to dial in low frequencies.
  3. Nice work. One of the reasons why server motherboards likely yield better sonics than what I'd call client motherboards is due to better quality components (resistors, capacitors and regulators in particular). In my day job I work with ODMs who design computers and in order to meet the higher server specs for constant uptime to manage critical data these components are much better quality than the 1-2 year longevity requirement for your run of the mill Acer, ASUS, Gigabyte etc. client motherboards. Then there are trace length and layout requirements that, for client MBs the ODMs will cut corne
  4. It depends on the magnitude and phase shifts of the impedance and also the delta of sensitivity. There is no generic multiplier.
  5. Correct. My point was WRT yamamoto2002's comment which omitted impedance. And impedance is rarely flat across the frequency spectrum and some driver / xover combinations with low impedance in a loudspeaker draw more current; P = V * I = more power required.
  6. It's not that simple. A loudspeaker's efficiency is a combined driver output value. However, all drivers and their related crossovers don't have the same impedance. As such, a lower impedance drive/crossover will require higher current for the same output level assuming the speaker is frequency flat.

    Aqua linQ

    Thanks for the info. I asked about buying Aqua's EtherCon cable and the Aqua dealer told me it wasn't yet available. Can I ask - which Ghent audio ethernet cable you bought?

    Aqua linQ

    Ethercon is a connector type used primarily in Pro audio. Ethernet cables and Ethercon - connector cables are wired the same. After experimenting with a few few very short CAT 8 cables and an Audioquest Cinnamon I liked the AQ best so far. However differences are fairly minimal IME. I may go to an AQ Vodka since I seem to like the AQ flavor, if you will.

    Aqua linQ

    IME with my LinQ I2S is better than BNC but not significantly, it's marginal and likely not much depending on the resolution capabilities of the system.
  10. View Classified SOTM SMS200 ultra Neo + Sonore Signature LPSU For sale in used but very good condition is this excellent combo. This combination comes awful close to the Aqua LinQ at less than 1/3 of the cost. A few details - The SOTM SMS 200 ultra Neo includes: - The power supply board cap upgraded with a better than SOTM - cap, an Audio Note capacitor yielding more meat on the bones + fuller and more controlled bass. - It also has the optional BNC clock input. - While the unit shows 12V as the input on the bottom of the unit the i

    For sale in used but very good condition is this excellent combo. This combination comes awful close to the Aqua LinQ at less than 1/3 of the cost. A few details - The SOTM SMS 200 ultra Neo includes: - The power supply board cap upgraded with a better than SOTM - cap, an Audio Note capacitor yielding more meat on the bones + fuller and more controlled bass. - It also has the optional BNC clock input. - While the unit shows 12V as the input on the bottom of the unit the input voltage was reset via internal dip switches and it is set to 7 volts to work perfectly with the signature LPSU. - The latest firmware as of 7/25/20. - Does not include a stock power supply - includes the original box - The Sonore Signature Linear Power supply: - Includes the Cardas DC3 output cable. - I do not have the original box, but rest assured it will be packed carefully for safe shipment. The neo ultra with clock input + the cap upgrade = $1550 MSRP, the Sonore Signature LPSU = $1400 MSRP, asking $1550 for the pair or $950 for the neo and $650 for the LPSU. Thanks for looking!! Price reduced - $1400 for the pair.

  12. Aqua Acoustic Quality LinQ Network Interface review - July 2020 For starters, this review is almost as much about the SOTM Neo (+ capacitor upgrade) streamer + the Sonore LPSU combo as it is about the LinQ, allow me to explain.As we have all experienced some level of quarantining and social distancing our systems and good music becomes even more important, especially if you’re an audiophile. And with that excuse in mind, I was eyeing the next digital input upgrade - either a music server or a streamer/renderer. Not long ago I had purchased a SOTM sMS-200ultra Neo streamer/
  13. I believe the wiring was inter - board connections and probably 20 awg, maybe thinner.
