I got one GX2600 and three SA2300 amps. Here's a threesome showing each type. That's a vintage Soundcraftsmen DX-4200 Preamp/EQ on top.
A Stack of Three

Left Front Panels
Impedance matching switches adorn the front. Evident is part of the massive heat sink and "wind tunnel" for cooling. The air exits the front.

Right Front Panel
Plenty of LED feedback is available. Volume attenuators for each channel and stereo/mono autobridging switches complete the front panel.

Rear Panel A
I had a hard time getting good shots of the rears, so I had to disconnect everything and kind of jack things around. Here the real differences between the GX2600 and SR2300s is apparent. The GX2600 has built in crossover circuitry, CD horn correction, and sensitivity dip switches. Both have balanced inputs, "no touch" speaker terminals, and dual thermostatically controlled fans.

Rear Panel B
Beside typical modular power cord ports, the main point of interest here is the power rating into 2, 4, or 8 Ohms. Now you can see who's the boss!

Sound tests
I ran one SR2300 through a ProCo switcher so I could drive three different sets of speakers in turn, using the FAP T1 and XP50 DVD player for input.
The speakers were the ol' trio: L250, XPL200, and L7 pairs. I chose one of the great Deep Purple tunes from Fireball, the well-recorded "No, No, No." off the digital remaster. This is a great mix of Blackmore's idiosyncratic guitar playing, Lord's Hammond organ, and Gillan's scorching vocals. Glover's bass is full and powerful. Paice's drums are smart, crisp, and punctuated.
For all three speakers, the Hafler created a strong, deep, wide soundstage. Placement was stable and precise. The sound was natural and open.
The L250 produced a big, powerful sound, with the bass and midbass being solid, powerful and convincing. The mids and highs were pretty good, but not as good as the other two speakers.
The XPL200 was mind blowing in the midrange and highs. The Ti domes were just incredible sounding. The cymbals were in the room. Gillan's vocals were in the room. The guitar screeched and the organ groaned--in the room. The bass was a bit less convincing.
The L7 was at peak form with the infusion of Hafler power. The cymbals were incredibly sharp, the midbass grunge on the guitar and the organ was powerful and convincing, the bass just as compelling as from the L250, with only the midrange falling behind as the L7's four-incher couldn't match the 09Ti from the XPL200.
These Hafler amps are powerful, clean, pro quality units that will drive just about anything. They provide an accurate soundstage and stable imaging with no apparent coloration. The fans might pose a problem to the sensitive of hearing, but I put the amps out of sight and sound, so I couldn't hear a thing. They make a super nice addition to my amplifier stable.
Out.
hey dome:
How did ( or do) the PS series compare to the other three speakers. I'll really like to know..
