    Buckeye Purifi Eigentakt 1ET9040BA monoblock power amplifier Stereophile Measurements

    When is it necessary to use these amps over the 6525? I have B&W CM10S2s with 90db sensitivity and 3.1ohm minimum impedance (6 nominal). Would I notice any difference?

    JDS Synapse & Neutron V1 USB Isolators Review

    I had a basic amp (Pioneer A400) that once picked up transmissions from a fire engine across the street. Always found that very strange.

    JDS Synapse & Neutron V1 USB Isolators Review

    Thanks Amir. I'm intrigued. All devices could have potential grounding issues but most people don't suffer. Is this a problem that can be defined? For example, I have no issues using a PC connected to a DAC via USB and connected to an amp via RCA.

    JDS Synapse & Neutron V1 USB Isolators Review

    Amir was able to respond in a professional way, as I would expect of him. He didn't take offence to my mild ribbing. Perhaps you should learn from him.

    JDS Synapse & Neutron V1 USB Isolators Review

    Ok, so are you now saying Amir that USB filters do something useful, this would seem to be opposite of your previous views. In an audio context, does it make the device sound better? In any other context, does it improve data quality? If neither, what's the point? Will you soon be working for PS...

    Example Speaker Measurements: Klipsch RP-600M/Neumann KH 150 (video)

    @amirm, could the drop here be an attempt at the BBC dip? I know this has been debunked somewhat but it was in the same frequency range. Also, does the crossover filtering affect the phase, in other words, should there be some nonlinearity to the response?

    Hypex Nilai500DIY Amplifier Review

    And I would agree. But as I said in my original post, I could tell the difference and despite watching with my eyes closed so I couldn't be influenced by the 3 guys in the room, every thought I had matched what they were saying. Every one.

    Hypex Nilai500DIY Amplifier Review

    I'd be interested in your opinion when the OEM version comes out, initial impression is that it's a step forward. We shall have to see.

    Hypex Nilai500DIY Amplifier Review

    I disagree. Whilst it would be quite impossible to ascertain subtle detail, tonal differences would come through. There was a noticeable difference in tone between the amps. Denying that is like saying opus can't pass more than one frequency.

    Yep, hence trialling it properly.

    Hypex Nilai500DIY Amplifier Review

    I do hate repeating myself, I am aware that a compressed opus audio stream is not good enough for a true comparison. However, if you can be bothered to watch the video you will be able to tell a difference (if your system is as revealing as mine). Read by comments on the post with the video.

    Not following too well buz. The difference was huge on the vid, I would therefore consider buying one after hearing it properly.

    I'm gonna order the stereo one I reckon. Would like to hear it in real life first though.

    There's a vid on YouTube and the Hypex site. Looks easy.

    Hypex Nilai500DIY Amplifier Review

    What's the effect of higher distortion at high frequencies? Is the amp likely to get harsher at high volume?

    I used to do the same thing, just a mispositioning of the a I guess

    https://www.youtube.com/live/NdZFAWe1Nxo?feature=share This was a fascinating test. I know, I know, I was listening to a YouTube video through my own system so what could I really tell. Well, every thought I had during the review matched what the guys in the room were saying so the differences...

    Rotel RB-1070 Amplifier Review

    This was a treat Amir, I own the RMB-1075 5 channel version as well as the RB-1080 200 watt version for the mains. Great performance for a 20 year old. That power on spike has tripped my electrics on occasion. Always found my 10 series kit to get a bit harsh at high volume, any idea why?

    Octave Music Don Grusin High Resolution Music Analysis (Video)

    Hey Amir, great work as always, couple of questions. 1) I suppose Octave would make the point that not having filters involved would improve the audio quality, any logic to that? 2) We always talk of the extra over 22KHz but isn't the real point of high res to give finer gradations in the audio...
