Phonic Max250 or Behringer A500 for speakers 93db??

Brit01 · 28th July 2008, 02:47 PM

Still can't make my mind up on which power amp to buy.

1) Phonic Max250 - 60 watts x 2 at 8 ohms (will be buying 2 amps to upgrade with X-over at a later date).

2) Behringer A500 - 160 watts x 2 at 8 ohms (2 again amps again)

As my Kipsch F-1 are so sensitive maybe I get away with the Phonic amps and save myself 180 USD.

Time is ticking as my local store os offering 25% off with my bank visa on Tuesday!!

I have no idea re the Phonic, but all else being equal, more power is not a bad thing.

My forthcoming speakers are more sensitive than yours, and I am specifying more power than this to get the clean peak levels I desire on occasion.

Don't forget the active xover.

Hi there Brett,

Can´t find 1 single review on the phonic.
Kinda strange as I understand this company has been around for some time.

I like the slim design on the phonic but concerned about the power output. Hard to imagine there is a power transformer inside considering how slim it is.

Not surprised re lack of reviews as this doesn't fit easily into typical phile or pro audio usage.

Go with the B.

Sorry zeonrider. Not sure what you mean by MAR1.

Have you heard the H class phonic 250? What do you base your conclusion on?

Thanks very much

Ok I found out that the phonic 250 is not toroidal but it is class H whereas the Behringer is toroidal but class AB.

Can class H have an advantage over the AB for a small amp??

Why on Earth would anyone build a 60 watt class H amp, unless they wanted a long run time off batteries?

Unless it's like the old Proton amps that only used the upper rails to get +6dB headroom instead of the usual 1.5-2dB.

Could you elaborate on your comment?

Sorry for my ignorance. I am just learning about the different classes of amps and tranformers. A newbie with a lot to learn.

Would this 60 watt (8 ohm) amp not perform well? What would be the consequences or typical use of this type of amp??

Cheers
