| ARC LS25 mkII adjustment Actually preamp tubes, in many cases, should be adjusted. However, biasing preamp tubes is not a simple task and it requires changing resisters. I believe the differences we hear when rolling tubes can often be how the tube is affected by the curr... | |
| down firing or front firing sub? Down firing is better for music because it blends more seamlessly with the main speakers. Forward firing is better for HT. | |
| speakers for a smaller listening room Bob_reynolds, You are playing with words and it all means the same thing. A speaker with 3 woofers is not the same as a speaker with only 1 woofer. There is a great deal of difference regarding the air those two speakers would move or try to move ... | |
| ARC VS60 bias Your AC voltage is higher than the voltage at the Audio Research facility. Lower the bias to 60ma as recommended. This is not something you do by ear. | |
| speakers for a smaller listening room Bob_reynolds, I disagree with this statement."The size of your speakers in your new room only means that you won't have to drive them as hard to get the same SPL." One of the main problems Zak42 mentioned is "lumpy" bass, an indication the room is... | |
| Is this clipping? Overdriving the amp = clipping. Overdriving the speakers is something else. Either way you stand a chance of damaging drivers. Many audiophiles believe their tweeters are not in danger with tube amplifiers because they clip so graciously. This not... | |
| speakers for a smaller listening room Your speakers are just too big for a small (11'x12') room. I doubt that room treatment will cure the problems.Stand mounted speakers have the best chance of sounding good in your room. There is a wide variety of speakers to choose from such as PSB... | |
| Warming-Up Amps w/o Inputs or Speakers Attached I agree with Herman. It is the output tubes that are in danger and running a tube amplifier without a load is a bad idea. Why not use an 8 ohm resistor in the place of speakers? | |
| Can I ground my preamp? "Did that in my system. Didn't solve the problem."Was it a ground loop problem? | |
| Can I ground my preamp? If you are having a ground loop problem you can drop the ground on your amps and leave the rest alone. You don't have to ground any components. | |
| Warming-Up Amps w/o Inputs or Speakers Attached I don't know about all of the solid state amplifiers out there, but I do know VTL and it is not recommended with your amps. | |
| Can I ground my preamp? Does your CD player have a ground? | |
| Extending an existing speaker wire This is not recommended. You obviously need a longer set of speaker cables or move your second set of speakers closer together. | |
| In need of Audio Research preamp recommendation Eee3, PLease explain "LS-25 which is a dynamic preamp". | |
| Martin Logan CLS setup I'm not sure that the CLS-1 is more demanding than the CLSII.Minimum recommended power for the CLSII is 80 watts and the minimum impedance is 1 ohm. |
