Phonic MAX2500 Stereo Power Amplifier

No longer available at zZounds
500W at 8 ohms stereo.

Phonic's MAX 2500 power amplifier provides 750 watts of power at 4 ohms -- ideal for medium- to large-sized venues, clubs, churches, etc. Phonic entry level power amplifiers maintain a solid performance at an affordable price. The MAX series amplifiers provide a range of different power options and features, and are rich in added features. Input to the MAX 2500 amp is achieved via 'combo' connectors that accept both XLR and 1/4 in. jacks, and output can be achieved through either Speakon connectors or traditional binding posts. MAX 2500 features ground switches, user-defeatable clip limiters, selectable high pass filters, and the option to choose between stereo, parallel and bridged operating modes, making the MAX series amplifiers ideal for real world, large scale applications.

I would buy the XP5000 over this one.
Sound
I have a P{honic 2500Max. It is a good amp, loads of power, it has blown just about any speaker I hook up to it with clean power, and handled any kind of crazy load with ease. I rate an 8 because the power switch stopps working occassionally, I have soldered the connections that were just press fit, but it still does this occasionally. I have to tap the switch area a little bit to get it to switch off sometimes. It's not too bad. The input jacks also can get a little loose. I switched from 1/4" to XLR and that fixed the problem. So far it's been going for over 10 years now, still use it every day. I am going to buy a Sunfire reference amp to see if the sound quality is up to par.
Features
Make the switchgear and the input jacks more robust.
Ease of Use
Easy as it gets...
Quality
Something to be desired in the switchgear and jacks, other than that- it is a workhorse.
Value
Great value. Maybe the newer amps are better in the switches and input jacks.
Manufacturer Support
Never dealt with Phonic.
The Wow Factor
I would buy another one, no bad feelings about it, although I would probably buy a crown before I look at a phonic for the price.
