Arcam alpha 7 to Naim 5 series (The demonstration)

Posted by: Geoff J on 31 March 2003

Firstly thanks to everyone who responded to my last post, I went for the demonstration on Saturday and thought I'd post the results.

I listened to the Nait 5 & CD5, Roksan Caspian CD & Amp, Cyrus CD7Q & Cyrus 8 amp. In the end I couldn't take my Mission 752 speakers but he set up the Mission 782. The speaker cable was not Naca5 (I'm not sure what it was).

I wasn't impressed with Cyrus so I forgot about that and went on to CD5/Nait 5 (which had been playing away before I got there) and Roksan Caspian's which were both impressive. In fact the Caspian's were a real surprise, I didn't think for a minute it would come close to Naim but in my view they did!! The Roksan sounded a little clearer than the Naim and timing seemed just a good. The Caspian's at only £1,250 seemed really good value .....if they weren't in the sale then they'd cost £1,900 which is obviously in a similar price bracket to the Nait5/CD5. In terms of build quality the CD5 was much better than the Roksan CD player ...the amplifiers both looked solid.

Out of interest I asked them to add a flatcap 2, once that was added it was all over for Roksan but then it's price goes up another £500+

I have 2 questions which I hope you can help with:
1. Does Naca 5 make a difference to such an extent that the Naim should have comfortably beat the Roksan?

2. (this may sound like a daft question, but I don't know the answer) My Mission 752 have 4 sockets on the back for bi-wiring, how do other people use Naca 5 on their non Naim speakers. Am I right in thinking Naim speakers only have 2 sockets at the back? Can Naim provide suitable jumper type connections?

Overall I'm really unsure what do, Naim has the build quality, good customer service and upgrade path but Roksan seems solidly built, excellent sound and is a bargain at the moment.

I'm going to hear the Linn & Rega this weekend but I'm quickly realising that choosing hifi isn't as easy as I'd thought (especially when it's your own hard earned cash) and I've got a headache weighing up the pro's and cons!!!

NACA 5 is regarded as part of the O/P stage on NAIM amps so yes it makes a difference. As for connecting NACA5 to two speaker posts the recomended solution is the "F" connector method. Basically two NAIM plugs one of which is connected below the other so that the speaker cable forms its own jumper. I don't know wether there is a picture somewhere but a search for NACA5 or even F connector on this site may yield some results as it has been mentioned a few times.
Hope this is of some help

Thanks Howard, I'll have a look.

Sounds easy to me.
If you like the Rocksan combination just as much as the Naim system, why spend more?

The only downside I can see is that once you're into the naim "hierarchy", there are plenty of routes for upgrading. Mixing in another manufacturer complicates matters no end.

So I'd suggest that if your considering further upgrades at a later date, go for the Naim gear, otherwise save your dosh.

Ref the Naca question. Yes it does make a difference. I tried several cables with my own Nait including QED silver anni bi-wire, Linn K20 and some expensive VDH stuff. Of none of the other cables were in the same league frankly, even the rather expensive VDH stuff.
