Help connecting my AMPS to my ML Sequel II's


Hi folks,

So I have inherited my dad's old system however it's been unhooked for awhile so I really don't know where to start with it.  All I know is everything was working fine until my mother decided to unhook it all after my dad passed.

2 x Martin Logan Sequel II's
NAD 2240PE Power Envelop Amp
Acoustic Research A-03 Amp
Adcom GFP-555 Preamp
Adcom Ace-515 AC Enhancer

I also have a turntable, tape deck, cd player however I know those all plug into the Adcom Preamp.  The AC Enhancer is very start forward.

The A-03 had the Record Phono and Source set to Aux setting.  I can provide pics of the back of the AR A-03 and NAD if needed.  

So do the ML's plug into the NAD and then connect the NAD to the AR then to the Preamp???

So not where to go from here?! So what I thought might be a fun project to connect with my dad is appearing not so easy.  Anyone that can shed some light on all this???

Thank you in advance

Not the kind of amp for these speaker, all ML ESL's have a very hard load for amps, here what Stereophile said about them in their measurements. I'll add they are also 1ohm in the highs
while the overall graph suggests a rating of 4 ohms rather than 6. The speaker drops to 3 ohms at 440Hz and to a hair over 2 at 24kHz, from which I infer that puny amplifiers, current-wise, should best be avoided. (Music has considerable energy at 440Hz, though only the occasional high-level cymbal crash will cause copious globs of HF current to be drawn from the amplifier.) MartinLogan claims a phase angle of 45° or less across the range; this graph confirms that to be the case, but the speaker's ability to shut down the Krell

Do you still have all the cables? If there two pair of speaker cables, probably the Martin Logan was passive bi-amped.
