| System that sounds so real it is easy to mistaken it is not live the JC 1+ puts around 300 watts at 16 ohms and can handle even higher impedance with absolute aplomb. @rauliruegas That amplifier is designed to operate as a voltage source. The Sound Lab has an impedance peak of about 30 Ohms in the bass. Tha... | |
| System that sounds so real it is easy to mistaken it is not live Their output impedance is on the high side but I am not using them to make low bass so, that is not important. @mijostyn The Sound Lab has its highest impedances in the bass region. That is why solid state amps struggle to drive them- they ca... | |
| Phono stage options - balanced with XLR both input and output... Really - I hooked up a Burmester pre with balanced phono inputs back in 1985. I'd be interested in knowing more about that. To my understanding Burmester introduced their preamp later. | |
| Open Baffle Experience Open baffle designs are WRONG. They emit sound that is out of phase out the back end. If you can show me an open baffle design that can emit sound IN PHASE not OUT OF PHASE from the back end then I will happily throw my box speakers away and we c... | |
| When someone tells you it's a $40,000 amp, does it sound better? With great respect, since I'm well-aware of your expertise- is it possible to assign a monetary value to those attributes? Yes- and depends very much on who is doing the assigning 😉 | |
| 4 ohm tap vs 8 ohm tap After a few LP's I began to not hear the bass. So after you all confirmed that I would not damage anything, I switched back to the 4 ohm tao. The bass is back. The suspension of any loudspeaker takes a while to break in. You might try the 8 Ohm... | |
| Why do Tube Amps sound more romantic v SS amps tube amp sound changes almost every 50hr due to tube emissions degradation, bias-balance degradation., accelerated resistor/capacitor aging, etc This statement is incorrect. Tube amps in general are far more stable than that! With our amps its ... | |
| Why do Tube Amps sound more romantic v SS amps To understand the dichotomy in tube versus solid state one must start forty or more years ago. Back then virtually all solid state was lean, trebly, and hard sounding. Tube equipment was warm and rolled off the treble and was wooly in the bass. ... | |
| preamp & amp compatibility @cdtd The output impedance of the DAC is really what the question is. It should be no more than 1/10th that of the amp; so if SE then 2.2K max. Typically If there is an XLR output it should have no trouble driving an XLR input, but in high end au... | |
| Boutique caps in oil... reliable? I’m a little curious though, is oil-filled the same as oil impregnated? When I think of oil-filled, I think of big cans from the old days. AFAIK they are the same. Oil is used to reduce damage from arcing. | |
| How much does rear horn loading add to full range driver? What do you think about using good quality 'full range' driver as a midrange in 3-way speakers. What do you prefer for midrange in high sensitive speakers - 'full range' driver or compression driver with horn? @alexberger In case it wasn't obv... | |
| Advice on a tube tester I see tested and calibrated tube testers for $1500 on ebay but I think I can get by for a lot less. You probably can- and it will need servicing and calibration. You may well spend the same amount as a result. When testers like that were made ... | |
| Boutique caps in oil... reliable? We've sampled a number of oil filled caps over the years. I've not seen a type that didn't develop electrical leakage, although I'm sure they exist. Electrical leakage is where the cap takes on some of the properties of a resistor- a voltage can ... | |
| How much does rear horn loading add to full range driver? It's common ASR wisdom that "fullrange drivers are hot flaming garbage and you should be deeply embarassed to evoke them in any conversation". FWIW a friend of mine has been struggling with 'full range' drivers for the last 20 years. He keeps ... | |
| When someone tells you it's a $40,000 amp, does it sound better? Better: Smoother, more detailed, greater center image palpability. Wider bandwidth, particularly in the bass. Greater speed and so on. |
