    Hilarious

    I just cant help laughing when I read this. I’m getting a lot of vinyl from a family member and she took a pic of this one very old gramophone disc. Seems the sales copy of the Hifi industry hasn’t changed one iota since the beginning.

    Audirvana Studio upsampling

    Audirvana 3.5.50 clunked out on Tidal streaming again for me this week. Cant play Tidal beyond the “High” setting. As pissed off as I am about it, I just want to listen to music. So I sprang for a Year subscription of Studio. I gave Studio a quick try on the trial period when it first came out...

    Plankie amp hum

    I’m using a Geco Emma plankie amp to drive a pair of subwoofers. I’ve had this amp connected to a Wadia DAC before, over RCA driving a pair of small monitors, and it was quiet. Since I’ve connected it to the subs, I’ve got a barely tolerable hum over the subs. Its audible from the listener...

    Inferior quality from China

    This is a first for me. I bought some cheap twin flex for messing about in the garage from a local hardware. Today I vacuumed out my workshop, and I always pass a magnetic pickup through the dust collector in case I vacuumed up a tool or something valuable. Big surprise, I pick up a piece if...

    Big thanks to @ghostinthemachine Dewaudio Dewald

    I purchased that ATC amplifier thats been floating around here for a number of years from Chingy a month or so ago. I knew the amp quite well in a previous owners system, and I’d always liked it. Unfortunately, the amp started tripping a DC offset fault about two weeks after I got it. A heavy...

    Need help with a little circuit

    Im having trouble figuring out what the problem is with this little board. It is a board that shorts the outputs when off, of a valve preamp. Probably to protect against on/off transients. 16v AC comes from a secondary winding on the transformer. Its rectified, regulated to 12v and smoothed...

    Modern HiFi quote by Art Dudley, Stereophile

    I just saw this quote from Art Dudley on a members signature: "Modern hi-fi is little more than a way of getting electricity to pretend that it's music." Art Dudley, Stereophile That statement is of course absolutely correct, but what brings about my post, is that it can be construed in...

    Help with sealed box subwoofer build

    I bought the AE woofers from Stu. I want to offload LF duties from my mains to a pair of subs I plan to build with those drivers. I have the ability to cross over at 70/100/140hz with 6/12/18db slopes via a Bryston 10B. I have basically got everything in hand to start building, as soon as I...

    Cables, electrons, power- think again

    I don?t pretend to grasp what?s happening. But it seems we MUST reimagine exactly what the cable does: https://youtu.be/bHIhgxav9LY

    Question about Geco Audio Emma

    I got a Geco Audio Emma amplifier to play around with. The amp board states 100w. I imagine that rating is for an 8ohm load. I want to use it to drive two 4 ohm subwoofers until I can find a dedicated amplifier for the subs. One channel per sub. The sub drivers are very power hungry- rated for...

    Amplifier input shunted by capacitor

    I?ve been wanting to ask this for the longest time. The specification for my ML 23.5 states that the input impedance  is 50k Ohm shunted by 1.5nF. If I?m not mistaken, there is a small capacitor in parallel with the inputs. My question is, what does that capacitance do?

    Anyone seen or heard from @Tom

    I?ve never met or interacted with Tom, but from his posts here since I joined I could tell he is a caring individual and seemed to be falling on hard times. Still, he had time for others. I noticed he hasn?t been online since March. Does anyone have a means of contacting him?

    REW room plot- how bad is it?

    I borrowed a Umik-1 from someone a few weeks ago. I played around with it a little and managed to get an averaged curve for my room at the listening position. I have no idea what I?m doing. My question is: how bad is my room?
