| Poor Fritz Hey Erik, Who is Fritz? What speakers does he make? | |
| Atma-Sphere MA-1 amps @twodolphins If you have older Sound Labs, prior to the 'toroidal 2' backplate, there are some simple modifications that can be done to improve their impedance and efficiency. This makes them sound better too! This involves removing a resistor in... | |
| Is static the culprit? If temperature is involved this problem can be caused by noisy transistors in the input section of the amp. I've seen this a good number of times. The capacitor failing didn't sound right to me as soon as I read it- if caps start to make noise, it... | |
| Woofer pumping possibly due to tube amp when playing vinyl ^^ +1 My phono section has bandwidth to 2Hz and no worries about woofer pumping- my system is flat to 20Hz and the woofers are calm unless there are bass notes. The KAB knocks out low frequencies and part of the reason it sounds different is not o... | |
| Tube amp bias adjustment advice @mmporsche The first step is to swap the interconnect cables left for right at the inputs to the amplifiers so that you can determine if the amps are at fault. It could be something upstream.If the problem stays put => amplifier problemIf the p... | |
| Cassis Grounding Solution There is a standard for balanced line connections. It is called AES48 (Audio Engineering Society file 48). You don't need at that grounding stuff; the shield is supposed to be tied to pin 1 of the XLR connection. If everything is in conformance, t... | |
| Pre Amp comparisons Your musical taste won't have anything to do with this. Amps and preamps have to be faithful to the signal, not the genre :) What makes it good for one genre will make it good for another.Do you want a balanced preamp or single-ended? | |
| Musical Fidelity Phono preamp loading 47K is the standard input impedance for a phono section, MM or LOMC. If this were mine I'd using a DVM and measure the resistance between the connections of the RCA jack and see what's there. I'd also use the DVM to see what the RCA plug thingys a... | |
| Guidance for choosing step down transformer for audio gear If you are using an isolation/Step down transformer, if the transformer is loaded past about 50% of its capacity it will begin to make significant distortion on its output.Its the 5th harmonic of the line frequency that becomes problematic- this h... | |
| Automatic Room Correction has won the Subwoofer Wars Sir, do you not understand my role here?? :-) I'm going with 'no' on that one...Seriously though the title doesn't seem to be what the thread is about. | |
| Are my standards too high? Folks, last time the OP did this, his entire thread was removed. That was a good thing. Since he is clearly trolling, all you have to do is report this activity to the moderators. The 'Report this' text appears at the bottom right of any post incl... | |
| Replacing Amp Caps The manufacturers names I have seen and assume there will be minor SQ differences between them?Not really. The total value will have a larger effect, and even that will only be audible at higher power levels. Also, they use 10/32 threads so your o... | |
| Vertical component placement? @unsound Yes. | |
| Vertical component placement? Very possibly! Most heatsinks are aligned assuming a certain orientation, since heat rises. Heatsinks can be found an any kind of audio equipment as they are used with regulators as well as of course power transistors. | |
| Automatic Room Correction has won the Subwoofer Wars I'm seeing the title of this thread as clickbait.Unless we are talking about DBAs vs oldschool, there are no 'subwoofer wars'.Now one thing I'm not seeing here so far but Duke did allude to it is the Total Room Energy which dominates the room soun... |
