Why? What didn't you like?
A good point plus a two box amp does not necessarily have to take up more space than an integrated. My Dynavector combo are more physically compact than the hulking great JVC integrated I am using at the moment.If an amp is going to be two box then a pre/power with the phono stage built into the pre makes far more sense to my mind, and certainly opens the door to a lot more choice.

As you haven't specified a budget, or system context, or some idea of what is 'best'' for you, then this is just a bit of fun. The winner is;

Very difficult question since in the grand scheme of things we've all had limited exposure to the entire market - even dealers.
That said, from those I've heard and based on a mix of performance, style and value:
Cyrus 2 - a controversial choice perhaps but later ones had a die-caste chassis, lots of power, could drive just about anything and had a cracking on-board MC stage.
Musical Fidelity B200 - wins big on style but a nice sounding amplifier with none of the weirdness of the very toasty A1.
Naim NAC42/NAP110 - yes I know, I'm cheating it's a pre/power but you can place them side by side with the same footprint as a typical integrated. Plus they were designed to work together. Forget the Nait (good though it was) this has the original Naim sound in spades and looks 'right'.
Exposure X - Rare to see an integrated amp with a fully regulated power amplifier PSU. Controlled and tight.
Onix OA21 - (sorry I know that will touch some nerves) - the original was superb, great sound, classic simple looks and offered great value.
There are plenty more but most of those are older designs from the 70s...
maybe a Leben c600?
I’m actually really enjoying my Nait 5i, if we’re specifically talking sub £500 used integrated amps, it’s right up there. I’ve had an original red LED Nait, an Olive Nait 2 and a Nait 3r, all very good. To my ears, the Nait was a fun, peppy sounding little thing when you weren’t asking to much if it… the Nait 2 had more depth to it… the Nait 3r exchanged a little of that depth for a bit more punch and the ability to drive trickier speakers… and the Nait 5i does the best bits all of the above, but lacks a built in phono stage option, not sure why it doesn’t get more attention.Naim Nait 5i range are with passive pre, there may be others
As I alluded to above, if you’re spending £500-£600 or less, this is a pretty good list. I’d like to spend some time with a Sugden A21a.Naim Nait 1
