| How to isolate turntable from footstep shake or vibration His point being too many people put off doing until they can figure out how to do it perfectly.Perfectionism is procrastination and absolutely nothing else. | |
| Class D amps seem poised to take over. Then what? ...yes, but is Class D stable into 2 ohms?Yes, depending what most meanings of the word 'stable' are. Yes, a class D will not go into oscillation when presented with a 2 ohm load (instability can result in oscillation- so that's one meaning of the... | |
| Importance of the Preamp in a system Back to my original question, I’m kinda leaning towards the Freya/Sim Combo. I’m curious though if synergy is so important'Synergies' such as pairing a dark preamp with a bright sounding amp usually end in tears- upon seeing how many $$$$ went dow... | |
| Dynaudio Evidence Temptation and tube amps? If you look at the specs on this speaker you see its rated 90dB sensitivity with a 4 ohm impedance.Tubes do not double power as impedance is halved (if acting as a voltage source they will cut power in half as impedance is doubled).So efficiency i... | |
| Different amplifier class for different music genres? However, I also have 3 others,KRELL D-SonicCODAthat sound different with the same music. I wonder which one of those cheated?They probably sound different with different music too. Whatever coloration they have with one genre, it will be the same ... | |
| How to isolate turntable from footstep shake or vibration I have an oscilloscope program so when I get the table I'll have a look and see if there is any unusual distortion at various frequencies. You'll need an LP with test tones. I cut some low frequency stuff on my lathe; its easier to see when lower... | |
| Class D amps that are superior to all or most? I borrowed a friends class D with about 300 hours on it and didn't like it. Harsh is the best word. Try a different amp. Not all class D amps sound the same, just as not all solid state or tube amps sound the same. | |
| How to isolate turntable from footstep shake or vibration I have been using a Sota since 1981 and have had it on everything you can think of playing through ESLs. I have not found anything to be as important as using a dust cover during play attenuating airborne vibration by as much as 20 dB (not sure... | |
| Gain and linestage Nelson Pass says it well here. Nelson Pass,"We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more.Think of it this way: If you are running your volume control down around 9 o’clock, you are actual... | |
| The Intellectual People Podcast - Ethan Winer (RealTraps) I believe humans are insensitive to distortion until it reaches high levels especially in lower frequencies where we seem to tolerate a lot.The brightness of traditional solid state is caused by distortion- and not very much of it if you believe ... | |
| How to isolate turntable from footstep shake or vibration Sadly for those who love them as one of the best sounding small signal triodes ever built, the 6SN7 is one of the culprits for being especially microphonic.Actually @lewm IME the 6SL7 is the more problematic tube compared to a 6SN7. @mijostyn Just... | |
| FULL RANGE vs. SUBWOOFER+NO FULL RANGE You can make it work either way but its easier with a sub or subs (especially subs).In most rooms you run into a problem with standing waves if the room has regular dimensions. This can cause a loss of bass at the listening chair- or maybe (less c... | |
| How to isolate turntable from footstep shake or vibration ARC put tube "prophylactics" (damping rings?) on the tubes. I have no idea if this cuts "microphonics" :) of course it does! Warren Gehl of ARC came up with that material (he also designed the Sumiko Analog Survival Kit) and it is one of the best ... | |
| Class D for a Tube Lover @audiodwebe Another way of dealing with heat is to install vents in the ceiling and use ductwork to move the air out of the house. This is often less expensive than air conditioning to install; its certainly less expensive to operate and also make... | |
| Tube vs. Solid State Amplifiers certainly would like to own an Atmasphere valve amp. Understanding the options better would help in deciding which one. In the smaller amps there are three options- copper foil Teflon V-Caps for coupling capacitors in the amps, additional filter c... |
