    GRIMM Audio LS1c & SB1 DSP Speaker Review

    Sure, but I'm not convinced that wider is always better. The KH150's dispersion looks a bit smoother from 400 Hz up but especially above 1 kHz. I imagine it comes down to personal preference, but I'd rather have a higher ratio of direct to reflected sound as long as the off-axis response is...

    GRIMM Audio LS1c & SB1 DSP Speaker Review

    This is definitely a case of "I'd have to hear them" to get a sense of what they are about. By the numbers, The Neumann KH150 seems better in just about every objective way. https://www.audiosciencereview.com/forum/index.php?threads/neumann-kh-150-monitor-review.39922/ The most significant...

    Poll for Topping PA5 owners only please.

    I've had mine for over three years. Still going strong, but I had to replace the L50 headphone amp I bought at the same time.

    Understanding the state of the DSP market

    In almost a decade using Acourate, I've never encountered a need to build active crossovers. However, I am aware that Acourate can be used to do this. I guess I still don't care about timing beyond what's required to take a valid end-to-end impulse response using REW. ;)

    Understanding the state of the DSP market

    I think the part I'm missing is that I don't know what you mean by "step response verification measurement". Perhaps you can clarify. When I say that I "don't care about timing", I mean that I'm not attempting to use the impulse response start times to calculate delays or temporal offsets among...

    Understanding the state of the DSP market

    Perhaps I misunderstood your use case. All I'm doing is verifying the effect of room correction filters on the combined response of the loudspeakers (all drivers) and room at the listening position. It's not obvious to me that you can use the acoustic time alignment "chirp" to measure the time...

    Understanding the state of the DSP market

    Correct. The chirp is just to force REW to pause recording until after we've hit "Play" in Roon...plus normal FIR delays and speed of sound, etc. Otherwise, we don't care about the timing. In the past, I've had some luck hooking up Acourate Convolver with REW via ASIO to do the same...

    Understanding the state of the DSP market

    I have not tried Focus Fidelity yet (on my list of things to play with in 2025); however, like a number of folks here, I've been using Acourate for around a decade, most of that time via Roon's convolution engine. With Acourate, I experience the opposite effect. Not all recordings have an...

    Understanding the state of the DSP market

    I do exactly the same thing. Since DRC via DSP is very much a garbage-in/garbage-out operation, I feel this sort of verification is essential. It does not happen often, but sometimes the results are rather inconsistent with Acourate's predictions. Reasons vary, like using the wrong mic...

    Axpona 2025

    I poked my head into most (but not all) exhibits at AXPONA this past weekend. Here's a link to photos that I took along the way. https://photos.app.goo.gl/s34LZdzfoYVXz39z8 After I took a photo or two, if I liked what I was hearing, I sat down and listened for a while. My general observation...

    Topping L50 Review (Headphone Amp)

    Yes. Thankfully, the replacement i purchased works perfectly (so far...)

    Topping L50 Review (Headphone Amp)

    An update to my story: the replacement L50 that I ordered from Apos arrived today. The power adapter that shipped with it also measures 20.4V AC. I realize this is unloaded, but it still seems high. Besides that, it sounds terrific. Better than I remember, but perhaps I've just missed having...

    SMSL D-6s Balanced DAC Review

    Hmmm... difficult to say. At one point, I thought I was hearing more pronounced or engaging bass impact from the SMSL D-6s than my Gustard X16. But it may have been just the track I was playing, volume level differences, or what I ate for breakfast that day. Both DACs have ruler-flat frequency...

    Gustard X18 Review (Stereo DAC)

    I just tested, and I hear exactly the same thing in exactly the same place. Between -22 and -22 dB.

    SMSL D-6s Balanced DAC Review

    Congrats. I've had no significant issues with my D-6s, and after a year or so, it's still the DAC that I recommend most often to friends. I'm not a huge fan of the USB type C input, but it is what it is. My Google Pixel 7 Pro has a USB C jack that I've probably plugged and unplugged over 1,000...
