Ok, so I've had the PM7001 KI Sig up and running non-stop for about 18hours now.
In comparison with the PM66SE KI Sig these are my observations:
This amp really opens up the Rogers LS55 speakers. The extra depth in detail on almost everything I heard was like the difference between night and day. It just feels like everything it driven with more controlled power
For once the older and lesser PM66 feels muddy and unclear.
Those beautiful shrill vocals from Nanci Griffith's live recordings really got the hairs on my head tingling.
Rainbows Difficult to Cure was presented in greater detail and the speedy fingers of Richie Blackmore were heard with much more purpose.
The guitars of Tesla were made to swagger in confidence
Every Royal Philharmonic Tchaikovsky piece was sublime and every instrument could be heard in unison yet singled out at will.
To see how well this amp was sonically and dynamically engineered I changed the bi-wire back to normal and the deficit was immediately noticeable.
I've decided that unless I can get hold of some seriously top class and much more expensive speakers, there's little point changing the speaker setup.
I hooked up a borrowed Arcam 192 CDP for good measure and this has now come high on my list for the next upgrade.
If the PM7001 KI Sig felt like I'd just spent £2000 on upgrades, the Arcam 192 felt like another £500 (despite it's c. £900 price tag)
The CD6000 Original SE was a good player, but this piece of kit seriously limits my setup.
The Rogers will be spared for another day.
I can do nothing but recommend this PM7001 KI Sig amp to anyone looking for a superb heart to their system. It doesn't miss a beat.
I never thought an amp could breath this much life back into what I already thought was a superb setup.
Well I've never been that keen on Arcam players tbh, but there are a couple of bargains out there right now as the Divas have been replaced by FMJs. But at any given price point I like the Cambridge 640 v2, the Rotel RCD-06, the old Rega Planet (haven't heard the Apollo), Primare, blah blah. And the second-hand market opens up some fabulous near-high end options for good money.........
