Excellent review HR-
earlier this year I did spend some time w/ this integrated amp and its matching cd player. Excellent sound, very pleasing. Simple set-up that does not require any critical skills. Disclaimer:
I am a separates guy.

I have heard though not had the privilege to own a Naim product.

I'd be interested in some comparison between the Naim Nait 5si and the recently reviewed Arcam FMJ A19.

This would be a good intra-UK integrated amp comparison, especially in view of the price of the Arcam FMJ A19, at almost 1/2 the price of the Naim.

And, for good measure, I'd really like to know of the compatibility of the Naim, or Arcam, with the Dynaudio Excite X14 or Focus 160 that have made the pages of Stereophile recently (the 160 as a come-back recommended component, and the Excite X14 as a new product).

Nice Review, thanks!
Would be interested in more comparison between these two, as I consider one of them to pair with the LS50.

I auditioned the LS50 with Arcam A19, Roksan Kandy K2 and Naim Nait 5si. Same room, same condition (Marantz HD DAC 1 as a source, music was alt rock, indie pop).

Naim>Roksan>Arcam.
Arcam is notably the weakest amp here, while Roksan with it's great control, sound stage and power still doesn't sound so clean and lacks the fineness of Naim.

I have this amp I must say that the amp is absolutely excellent! If someone have it or he is considering to buy, one should get it paired with Naim Nac A5 speaker cable (at least 3,5m long as manufacturer recommends). It will substantialy improve already excellent sound - almost unbelievable difference.
