    Channel Separation?

    This all goes against intuition. Stereo signal separates right and left in a way that confuses us nd we think we hear real space. My xtc filter doesn’t want the two mixed up. So why is channel sepration enough at 50 or even less db? If we had zero would we not be listening to mono? I appreciate...

    Passive Preamps - Transformers

    This would be to use with a dac/xtc filter without a usable volume control. Sounds like I ll stick to active.

    Passive Preamps - Transformers

    I have listened to a couple of transformer based preamps to very good effect. No careful double blind listening yet. I was wondering if you could point me to any discussions, measurements and opinions that may have been posted here. Very big picture it seems that these won't beat the insane...

    Standards for Audio Electronics Measurements?

    What is the argument against multi tone and also assessing different signals against different loads? Or what is the argument that one tone at 1khz tells us everything? The way I read these measurements is: so far so good, when it comes to these measurements there is no problem. Αnd not: if...

    Topping LA90 Discrete Amplifier Review

    We are so fast at attacking everyone else that even blinks the wrong way on other sites that we should keep ourselves to a higher standard. I am not in anyway suggesting there is intention. Just that this is absolutely read as a comparison by reasonable non expert non regular readers, especially...

    Topping LA90 Discrete Amplifier Review

    These amps are definitely competing amps for people who can afford either, focus on measurements and who plan to bridge them. This comparison is misleading.

    Topping LA90 Discrete Amplifier Review

    Am I correct that the review compares the power measurements of LA90D in bridged mode vs the Benchmark in stereo (which specs at 480W at 6ohm)?

    Blue Jeans Cable Isolation Transformer Review

    They do explain what they mean, I believe they connect the shield in the receiving end and float it on the other side. Whether one thinks that makes any difference is up to the customer. On burn in time, got me there! Love the ATTENTION! Making sure they force the belief.

    The New King?

    Is it impressive? Or is it a marketing strategy focusing on one or two measurement characteristics and causing people who believe it matters to keep buying? If they believe in the meaning of measurements, shouldn’t they just say: none of this is audible, so we are fine with our previous model...

    Topping E70 Stereo DAC Review

    So what's the point in D90SE?

    Dan Clark Expanse Headphone Review

    I asked a simple question: Amir is mentioning “spatial qualities”. Which measurements are reliably predictive of those qualities? This is a glaring issue when two headphones seem to measure so similarly. And are made by the same guy. If you don’t know the answer just say “I don’t know’. No...

    Dan Clark Expanse Headphone Review

    I don't think I am. I am just saying that anytime anyone says they hear something different then the immediate reaction is to talk about level matching. its getting old. Secondly I am not talking about any given listener in any given room but in the same listeners in the same room with these...

    Dan Clark Expanse Headphone Review

    Yes I know that is the standard answer here. that the comparisons aren't level matched, that the listener isn't double blind etc etc. My surprise is noted because we just acknowledged here that one can't pinpoint where some of the sonic effects come from simply by measuring (or at least that is...

    Topping G5 Review (Portable DAC & HP Amp)

    I find lightning to be surpassed by a large margin by usb c, less robust physically and a pain to have to bring both lightning and usb c cables for even an apple only system. It is ridiculous. So much so that the European Union put an end to with law! Having said that, one is free to not use...

    Dan Clark Expanse Headphone Review

    The same speakers exhibit different imaging and space properties with different equipment prior to them. If there were measurements that one can point to then I would assess that based on how the equipment measures and not only what I hear.

    Dan Clark Expanse Headphone Review

    I think these guys have tried to explain measurements and how they affect what we hear: https://www.rtings.com/headphones/tests/sound-quality/imaging
