My system at home consists of a Uniti CORE, 272, 300DR through SL cables into PMC Twentyfive.26 speakers. The original system took a little tweaking to get rid of sibilance and treble harshness; a 250DR was replaced by the 300 (a big difference) and the NACA cables exchanged for SL cables. That also smoothed out the reproduced sound noticeably.
I took the 272 into my dealer recently (a wonderful man – Harry, at Audio Genesis) for a firmware update, and whilst there had the pleasure of being able to hear an ND555 + NAC252 combination, with a NAP 300DR into NEAT Ultimatum XL10, and then A-B’d with my 272 and the 300.
From the 272 to changing the streamer only, there was an incremental improvement in all aspects of the sound (detail, soundstaging, presence), and then stepping up to include the 252 gave a further improvement.
The question is: was I blown over, superly impressed? Well, not really. Yes the improvements were nice, but IMO not worth the huge cost increase. The streamer alone cost more than my whole system. I left happy, knowing that there is still a superb system at home to be enjoyed and that the 272 is a seriously good piece of kit. Just for old time’s sake, I had a listen to my first NAIM system which I still have – a NAIT 5i, CD5 player and Spendor S5e speakers. Total cost of that: $5000. I then could really appreciate and was grateful for what the current system is capable of.
I read a lot about tweaks and upgrade-itis; not too much about satisfaction with what one already has, so I thought I would write in.
Just a little more. I had originally connected the CORE to the router by cheap cat5 ethernet cable, and then used wi-fi for the 272-router connection. Harry suggested I use direct connections (as NAIM recommend as well), so I obtained a Netgear 1000 switch box, and used cat5 cable to connect the CORE and the 272 to the box. Then – having read a little on the qualities of Ethernet cables - I swapped out the cat 5’s for some cat6c shielded which were also inexpensive. An amazing difference, especially with internet radio. I went further and used cat 7 (Chord C-stream) interconnects, and I have to say I didn’t like them. They seemed to make the reproduced music more “dense”, so out they went and back with the much cheaper cat6c shielded cables. Happy again, and that’s where I am staying. Cheers everyone.
