That sound is right for me.

@runwell    I didn't say he is selling anything.   I just said I didn't understand your post, and I still don't.

You say "which pre and power could have that high in the market?".  What do you mean?

And I'm not sure it's helpful to evaluate amplifiers listening on headphones to someone else's system recorded and published on YouTube.

Buy a Shindo preamp and amp. Then a pair of Altec Valencia's. This is what esteemed Stereophile reviewer the late Art Dudley used at home. Along with a Linn Sondek and Garrard 301 turntables. He was an analog guy!

And if you need to add an active tube crossover for the Valencia's then get an old Audio Research tube crossover and another Shindo amp for the Altec 811 horns. Me, I'd just use the stock Altec speaker crossover.

I had a pair of Valencia's for awhile. Traded them for a pair of Madrid's.

I have several time listening Altec speakers at site and felt extra  well each time. These are all old equipments and some one can handle it if there is small problem, and I am not sure I can handle it.

In another topic, we are discussing when is the best time to make the best hifi device. And some professional guys said it is now.  So I am wondering if I can buy the current model  with such good sound?

 Thanks very much @jasonbourne52 ​​​​​​, we are  in the  almost same position to understand the sound.

I just can't handle old equipments by myself.
