Amps for Sasha


Thinking of the Pass Lab X350.5 or X260.5 as they're about the same price. Heard the class A INT30 is also a good match. Any comments?

I would definetively take the stereophile measurements seriously ,i consider it a magazine with a more scientific aproach ,the rest is more screaming about whats the next best thing " or what is the bestëver" or "what is absolutely the best"
With a impedance drop to 2 ohm at 86 herz i would definetively take a stable amp with good currentdelivery at that impedance, to make sure you hair a drumsolo on high volume without strain when you want it
Loudspeakers designed under this paradigm are said to be 'voltage driven', as they expect the amplifier driving them will produce constant voltage despite the speaker's variable load impedance

Why should a certain speaker (expect to) be designed according to this paradigm , is that a design feature which they had in mind ,as its not a must for a crossover to function as far as i know ?
i personally try to design a speaker with the highest impedance in the crossover as possible just to avoid problems , but not by using artificial networks .
If the sasha is a very tube amp friendly load ,i dont know personally.
i do know of certain speakers that have certain networks to accomplish a artificial smooth/higher imp.

I see it more in the way that ,if a certain voltage level doesnt drop with a heavier load(lower speaker imp ) than it is automatically shown that that amp is capable of instant greater current delivery meaning better loudspeaker unit control (important for dynamic swings for example) .
What also plays a rol is i think the musical taste of somebody , big/loud dynamic music sucks up more current than a quiet jazz combo for example ( i think that i have not measured that)
Does it hurt to have a big powersupply /constant voltage/ power doubling amplifier to lets say 2 ohms, i think absolutely not .

I want add one more thing , a lot off loudspeakerunits that are used by manufacturers today (I know some improve/make there own) have increased efficiency due to their design and neodymium magnets drive for example , this will usually lift the overal efficiency of the speaker and with that also the need for high power /high current (transistor)amps .
And become more tube friendly
