lynnm Posted September 17, 2004 Share Posted September 17, 2004 I use an Antique Sound Lab Aq1003DT ( PP EL34 outputs upgraded to EH6CA7's) with my 1982 Khorns. The Sovtek EL34s sounded fine to say the least but the EH 6CSA7s took the sound to the next level. Quote Link to comment Share on other sites More sharing options...
Parrot Posted September 17, 2004 Share Posted September 17, 2004 I don't know you figure the "only 4 times as loud" calculation. But even *if* that were the case, doesn't it seem like 4 times as loud would be considerably louder? Quote Link to comment Share on other sites More sharing options...
wheelman Posted September 17, 2004 Share Posted September 17, 2004 I need a big fat warm 6l6 power tube sound with extended high and bottom end. I heard alot of tube guitar amps and that is the best for what I like. El34 is nice for a rolled off treble and a tight bottom without going too deep with a punchy mid. El84 is way to thin for me high end all the way. I know guitar tube amp tone pretty good and its got to carry on to stereo equipment. Am I close? Because that is right on the money with guitar amps.

NOSValves Posted September 18, 2004 Share Posted September 18, 2004 Nope sorry guitar amps are a completely different world although some of the character can be carried over to Hi Fi. Guitar amps are built to over drive a tube hence distortion ! HI FI is all about limiting distortion. Craig Quote Link to comment Share on other sites More sharing options...

For example, the difference between 30 watts and 300 watts is only TWICE as loud at the ear (in electical watts here) that is 10x the electrical current*voltage used at 30 watts. How loud does one need to go - that is, when does it become overkill? In my case, it depends on the source material. For serious stereo listening, 1 watt is absolutely PLENTY. For irritating the neighbors or for HT, the 300 watts is better. But technically, it is only TWICE as loud as 30 watts. That's the point.

That would be 0.3W to 3W to 30W to 300W (note the word "TO" three times). It is also 10 increments of 3 if you figure it that doubling the power (ie: 150W to 300W) gives a 3db difference... as it has 10 steps of double the power between 0.3W and 300W (10 x 3db = 30db) Even though the rule of thumb of 10db is twice as loud is well accepted, I find it somewhat of a relative thing. A difference of 10db is very noticeable, and many mute buttons only cut the volume by 20db, as a reference. Kinda like saying your coffee is "twice" as sweet as mine even though I have ½ a sugar and you have two sugars. One is definitely sweeter than the other, but how much sweeter is relative. OTH, those who argue about the differences between 110W and 90W is entirely trivial. Rob Quote Link to comment Share on other sites More sharing options...
D-MAN Posted September 20, 2004 Share Posted September 20, 2004 Ok, Ok, you caught me! It's .3 watts not 1 watt, sheesh! You guys! My meters are marked in increments of 3's (being an Mc300)... I was just rounding up for the 1 watt... So, I SHOULD know better than to argue with less than perfect numbers - or I'll get called on the carpet -probably as it should be...

D-MAN Posted September 20, 2004 Share Posted September 20, 2004 Rob, the "twice as loud" increase in decibels is +3db, not 10. The power equation is a 10 fold increase per +3db. DM Quote Link to comment Share on other sites More sharing options...

You guys! ---------------- It's THREE (3) steps like you originally posted as well as the 0.3W first value. I also think we are referring to the same (relative) rules of thumb using different adjectives: Double the input power (10 to 20watts) = 3db increase in output = a noticeable change in volume Ten times input power (10 to 100watts) = 10db increase in output = a doubling in perceived volume BTW, I find that even a 1 @ 3db change noticeable, but not as obvious as 3db. Just keeping you honest... Rob PS: a mute button will give the following Hundred times less input power (100 to 1watts) = 20db DEcrease in output = muting the volume Quote Link to comment Share on other sites More sharing options...
