The best tube poweramp. . What do you think about ? even the tube sockets are gold over solid copper ,most are cheap brass.Gold plated tube sockets are unreliable- gold is very soft as metals go; when tubes are inserted and then removed gold is scraped from the contacts of the socket. In time, the ... | |
why are built-in turntable rca cords so short? Phono cables need to be low capacitance. 20pf/foot is a good value; certainly no more than 33pf/foot. By the time you have a meter you'll have 100pf or so; this can have a big effect on how a high output cartridge performs! That's why phono cables... | |
I’m also worried about how much of the harmonics in the music is LOST by the amp? Can also be lost in the type of amp used, when phase shift happens to the 2nd 3rd 4th harmonic structure of the fundamental, mids and highs notes above in this case Class-D >1khz. As can be seen (red trace) there is 75 degrees!!!!!!! of phas... | |
Class D amps that are superior to all or most? I said To those who want to understand, why it’s better to turn off your amps, here it is simply as possible.(as they like to be drained and recharged otherwise a false permanent "empty floor" happens and your electrolytic power supply caps won’... | |
Amplification: what are the biggest advances of the last 40 years? Some audiophile friends and sales people are of the opinion that "older amplifiers are outdated' and therefore cannot compete with the better new high end ampsIs it true that the best newer amps always sound better than the best older units? No... | |
How to isolate turntable from footstep shake or vibration it sounds more like damping rather than isolation although it probably isolates at certain frequencies. If you want to have some fun put the stylus down on a stationary record and hook your phono stage to an oscilloscope. Then play a sine wave ... | |
Amplification: what are the biggest advances of the last 40 years? During a recent visit at my local dealer, I inquired as to why the new amplifier we were listening to was so expensive?@bobbydd High end audio isn't about price, its about intention. It is true that better parts are more expensive than parts of l... | |
Class D amps seem poised to take over. Then what? Just look at their independently measured 2ohm wattage figures (if you can find them) then compare to their 4ohm wattage figure, and see if the 2ohm even tries to come close to doubling the 4 ohm wattage figure, and post it up **** **** and if ... | |
What about the other way around? Assuming the reverse is true that wattage output will be halved as resistance doubles, would a pair of 15 ohm Rogers LS3/5As (82.5dB/W/M) be too much of a load for a 50 wpc Forte 1A?With ~25 wpc, should I be concerned about clipping?You're corre... | |
How to isolate turntable from footstep shake or vibration isomerically isolated? Does that mean rubber feet? No. Beneath my platform for my turntable I have some pads made of isolation damping materials- I don't recall the material (its certainly not rubber!). A different number of the pads are used depe... | |
SOUNDLAB ULTIMATE 545 While technically true, high powered Solid state amps Like the JC1 do just fine to 105 dB (as high as I have gone) for several reasons. The JC1s due to a programming error I made absolutely fried the high frequency brilliance control and I mean... | |
Amplification: what are the biggest advances of the last 40 years? From the perspective of an amplifier designer, these are the biggest improvements I've been aware of. OTLs became a lot more reliable- as reliable as any other tube amp. OTLs offer transparency like no other tube amp.Class D amps have been refined... | |

SOUNDLAB ULTIMATE 545 Duke is correct about Atma-Sphere but as a rule they work much better with solid state amps. The problem for most tube amps is the extremely low impedance at high frequencies. This requires a LOT of current. Big solid state amps with over built ou... | |
Is D for Dry? Class D... Ralph, don’t skew things around "to seem" to suit your next product. I did not say "won’t handle", I said will not get "the best" out of the Alexia’s bass because of it loading.We have the Alexia’s here in front of us and know what they like to g... |
