What's your favorite boutique speaker maker Audiokinesis. Duke is a great guy (probably best-known for his Swarm subwoofers). His regular speakers have always been a good combination of performance batting far out of his price points. Easy to drive and good on making bass for the size of th... | |
Woofer pumping possibly due to tube amp when playing vinyl Thanks! Is this affected by the volume control? | |
Never Owned a Tube Amp and Want Advice Regarding the sibilance- that really shouldn't be showing up at all, even on a new speaker (it might be bright until it breaks in, but sibilance suggests something wrong). Does it do this on all sources? | |
Tube amp bias adjustment advice but I asked my GF and she said it sounds balanced when seated in the middle.Yikes! Do you notice any hearing loss in other situations? | |
Plinius noise with balanced cables It might be that Plinius is using an additional circuit to convert from balanced to single-ended. This is a common practice (not one I'm in love with...). If the opamp associated with the conversion has gone noisy, that would certainly explain wh... | |
Cassis Grounding Solution A customer of mine had Tara Labs cables. I'm familiar with them.Our preamp was the first balanced line preamp offered for home audio use. Put another way, we introduced balanced line operation to high end audio, way back in 1989. If you follow al... | |
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... |
