    Help me replace my Genelec 8341's for the sanity of my beloved wife

    Surprised here that there's little 'decorator' comment re: several photo's & A/V setups that fail to mention that "Big Black Rectangular Elephant in the Room". IMHO, that noxious bleak dark window is a far worse looking 'decorative object' than nearly any imaginable sound box (or panel) you may...

    Are "non-conventional" speaker designs worthwhile, or just gimmicks?

    Again, so very much is all about the room! I've had 2 pairs of Genelec 8050A's for years, and their controlled directivity and ported bass provided "minor complications" in four rooms in two homes. Just as my Spatial M-3T OB's have had placement restrictions in some different ways. But one...

    McIntosh Transformer causing noise in speakers while disconnected.

    Earlier on there was an OP mention of an "older" 80 years, or so, house. Weren't the 60Hz standards for phase (active Volts) and neutral ('ground -return') or whatever they called them pretty questionable? As in: "if it hums, reverse the power plug at the wall", or "turn the plug 180 degs" etc...

    New Purifi amplifiers coming

    The input 'buffer' OpAmp used with the Purifi module provides additional gain. Some amps, like the MarchAudio 462, have switchable 20 or 26 dB gain to optimise system gain performance. Though most 'non-exotic' DAC's, Pre's and Amps available nowadays will happily sing together with no fuss or...

    What is generally the best material for speaker cones with the least compromise and most benefits?

    Fan-boy here for using Be tweets & mids. IMHO, it's mostly about the impulse response showing nearly no ringing on the lagging edge transient. No stored - delayed energy. Just the electromagnetic to barometric. Some details here...

    Everything you ever wanted to know about Line Arrays ( but we’re afraid to ask)

    There was the quite popular Shure Bros "Vocal Master" (often: "Blaster") systems long before the Bose Arrays. And the the grey box columns of all those mid-range drivers could often be seen in many churches & small auditoriums. Musicians would put them up on chairs or tables in club-hotel...

    [Poll] What is your experience with the reliability of the Topping LA90D?

    Can't help noticing that there is no circle to tick for PROBLEM not being addressed to customers & ASR readers. And its' being solved, or not, from the Guangzhou design & manufacturing guys. Somewhat disappointed with the "limited" response from this (presumably?) 'Quality Brand". jp

    Topping LA90 Discrete Amplifier Review

    Wish I didn't have to write this: But my first Topping LA-90 Discrete ( Post #232) has done the dirty on me after just about 1 month. So, I noticed it's input select #1 light rapidly blinking with nothing playing from Roon-WiimPro-Metrum Amethyst and I went over to the reasonably clear...

    Everything you ever wanted to know about Line Arrays ( but we’re afraid to ask)

    A very good overview of a Line Source for near field (domestic) use is here: https://audioroundtable.com/misc/nflawp.pdf A slightly old, 2003 paper, though he's very good on the subjects of V and H directivity index and for power tapering with floor-ceiling bounce reduction which helps the...

    Topping LA90 Discrete Amplifier Review

    CORRECTION: My post here #232 re: supplied mains power cord is ( Amirm was right! So sorry! ) a twin flat 'figure 8' cheapo with USA blades at the other end. Topping also supplied two UK-Euro adapters for same. Found this out when I got my second LA-90 Discrete three days ago (ordered 17 Apr) -...

    Topping LA90 Discrete Amplifier Review

    My LA90 Discrete via "AliExpress, BrightAudio Store" ordered on 25 March and received in Auckland NZ on 4 Apr, was supplied with a USA type mains plug end lead with a THREE (not a "little twin, flat 8") socket plug into their outboard PS pins. NZ is 50Hz/220-230 Volts, as I fitted an Aus/NZ...

    SMSL DO300 DAC Review

    You're right about that! Big confusion as I've bought 2x SMSL D300 (only a 'D' w/300) that have the new ROHM dac chip in a similar box. More confusing? And to my ears - or imagination - or its' output implementation, they sound 'slightly' different OR 'better' than my ESS (2x March1Khadas, &...

    Topping LA90 Discrete?

    Took a punt & got my LA90 Discrete via BrightAudio Store to DHL Guangzhou, H-K, to Auckland doorstep in just 9 days. Nicely packed in sturdy oversized double boxing with lots of stiff foam etc. And all was "waterproofed" with completely total box wrapped in lots of plastic packaging tape. Nice...

    Advice wanted: Taking over an HiFi Store

    Here's an idea from the other side of the world: From:The HiFi Store NZ<[email protected]> The Linn importer/dealer and other "reasonable brands" (Rotel, Q-Sound, etc) is quitting retail after forty years at "good" locations around Auckland NZ. He's told me their customer base has been...

    Teeny tiny people playing teeny tiny instruments.

    Have you listened on a full (floor to ceiling) line source type transducer set-up? IMHO, they "scale" more realistically. Although multi-tracked & highly processed recordings on most systems make sonic "reality" into a confusing cluster-f**k.

    WADAX: R Harley trying to explain a $220k streamer and DAC price….

    It is an outright insult to EE's everywhere that an audio company claims to very expensively make digitally encoded music 'better' by 'fixing the bits'. Ivor Tiefenbaum's dictum that "If you haven't heard it - you don't have an opinion. Period." is an irrefutable truth in our mysterious Land of...

    On the fence ready to buy VTV 1ET400A Purifi or VTV NC502MP hypex...?

    Yes, subjective or not, there are audible differences in these class A/B and Purifi designs. I presented my Kinki MX-7 and March 452 to the Auckland Audiophile Society - about 25 'experienced' guys. We swapped to and fro into a Q Acoustics MTM 2x 7"+ tweeter config with a variety of CD's via my...
