    Bookshelf Speaker Shootout

    BW limited pink noise can create level differences between speakers based on the usable BW of each speaker. For example a speaker with a lot of bass will play louder with real program material then the speaker with less bass if you calibrated with BW limited pink noise b/c the bassier speaker...

    Bookshelf Speaker Shootout

    Alex; OK your room looks a lot livelier just from the images shown. Typically its best to treat the first ceiling or floor reflections rather than treating the sidewalls. Sidewall early reflections are beneficial to increasing spaciousness but the floor ones not so much. Again how did you...

    Bass Management Basics - Settings Made Simple

    The 80Hz Xover has nothing to do with not being able to hear bass below 20Hz. That's a different subject. That said, 80Hz is a good pt b/c its about 1/2 octave below the frequencies where the ear can localize.

    Bass Management Basics - Settings Made Simple

    1/2 oct was meant as a guideline for the usable BW of the speaker, not the -3dB pt. I will see if I can clear up that text a bit.

    Spyro Gyra: The Deep End (2004) CD Review

    A lot of people have asked me "how come you've never done a Spyro Gyra CD Review?" to which I responded: "good question!". Since they are probably one of my all-time favorite modern jazz/fusion groups, I've decided to do FOUR Spyro Gyra CD reviews over the next several months: one for each...

    Bookshelf Speaker Shootout

    Alex; Great effort on this and it's much appreciated! I do have a few comments/observations: 1. You room seems pretty lively with the wood flooring, high ceilings, and windows, etc. Ever think about getting a thick padded throw rug to help absorb the first reflection point? This would likely...

    Question about DACs is it a big difference between a 24 and a 32bits?

    You purchased all good equipment. If you're not satisfied with the sound it most likely is NOT a function of poor DAC performance. You either need to work on speaker/seating positioning, or room acoustics, or both. If your room has hardwood/tile flooring and you have lots of glass in that...

    iBasso DX90 Portable Digital Audio Player Review

    The iBasso DX90 has generally been well-regarded as an excellent choice amongst the audiophile community as a mid-tier digital audio player (DAP). Incorporating a touch-screen, and high reference DAC the device makes hi-fidelity sound a portable option for the masses. However, with rival Chinese...

    Speaker break in

    Not only that but the small differences of a driver "broken in" vs "unbroken in" are mostly swamped out once loaded into an enclosed system. See: http://www.audioholics.com/loudspeaker-design/speaker-break-in-fact-or-fiction Danny Richie is a talented loudspeaker engineer, but some of his...

    Question about DACs is it a big difference between a 24 and a 32bits?

    32 bits is a myth. Johnson Noise (aka. thermal noise) inherent in analog electronics limits your noise floor to about 20-21 bits. So anything beyond that is digital masturbation. What is more important is the quality of the reconstruction filter, the board layouts, and proper implementation so...

    OPPO PM-3 Closed Back Headphone Review

    The PM-3 is Oppo’s third time around designing a planar-magnetic, closed back headphone after its highly acclaimed PM-1 and PM-2. But the PM-3 stands apart from its higher-end forefathers in a few key ways. The PM-1 and PM-2 are essentially the same design, both high-end luxury open-backed...

    Yamaha RX-Z9 BASS MANAGEMENT

    Not possible to hear vocals at 80Hz with a 24dB/oct LPF. 40Hz is too low and a waste of the sub. I'd stick between 60-80Hz if I were you.

    Yamaha RX-Z9 BASS MANAGEMENT

    I'm not 100% sure if the Z9 will truncate LFE. Some AVR's had a fixed 120Hz setting for that so unless I was able to test it with my AP, I couldn't tell you. It's been a long time since I reviewed that unit. LFE is only relevant in a discrete 5.1 Dolby/DTS movie. There is no LFE for 2CH...
