new amp for Altec Valencias

[diamondsouled]

Perceived doubling is 10dB... at least that is what the experts say... personally I think it is another of those subjective things about audio...

The idea is that 1 dB is the smallest increase in wide band noise that an average listener can perceive... and 10 of these units (10dB) is perceived as "twice as loud". 3dB however is clearly audible but not really twice as loud sounding but is twice the power and 10dB is ten times the power. Therefore to reach a level that is perceived as being twice as loud, whatever that means, does indeed require ten times the watts.

Thanks for the explanation Widg. It is a pretty subjective thing as you point out though.

It is cold here by anyones definition though. It has warmed up to -49 F from a cold of -58 F this morning.

It is so cold out that my farts have a wind chill factor. It is 49 below but they smell like it's 70 below!

Save them for internal heating. If you dont blow the bottom out of your world you may blow the world out of your bottom.

Some of these small valve amsp tend to soft clip so they sound more powerful than they should.

I will go with 6 db more power to benefit from any useful headroom over 8 watts ie 32 watts.

how come noe one has suggested keeping the 8 wpc and biamping with an inexpensive external active 2 way and SS amp?

Hi!

Ive just sold my 8w 300B amp that I was using to drive a pair of valencias.

It clipped at loud volume.

Im thinking of going for an accuphase amp, and have the choice of going for something low power (like 20w p/ch - all class A), or higher power (like class A for 10w then another 150w class A/B).

Just wondered if anyone who has these speakers (or similar) could share their experiences on trying different amplifiers -

perhaps to suggest models that they thought were a good sonic match,

or to give advice on the amount of power these things really need to be powered properly.

NB
I dont really want valve amps again.

If there is any way possible, try a Sansui AU-9500 with your Valencias.
You will remember me.

As his post was almost 4 years ago, I'm sure he already got an amp. Wonder if he even still has the Valencias?

Others searching on the thread subject may benefit some day.

QFT. I just acquired a pair of Altec 848A and will power with a McIntosh MC2300. 300wpc. That oughta be about right.
