I know this'll pee off the purists, but the MK1 Leema Pulse should be looked at as a future classic within it's price bracket.
I'm not sure what other integrated had a switchable phono stage. A few of the more brands now has a switchable ; has 4 x line level inputs, some brands has those; outputs for either a sub or power amp. Some brands can boast that; automatic volume setting for when you switch from one source to another, so you don't damage your speakers. No idea what other brand offers that. Collectively I've not come across any other integrated.
For the best bit: The sound. I've always had the belief, right or wrong, these new one amp does it all, incl. built-in Dacs can be detrimental to the sound. This is why: if you have a 3k all-in-one, in simplistic terms, the 3 grand has to be split between perhaps a Dac, streamer power and preamp and some have a phono stage. In addition modern amps cater for a whole manner of digital inputs/outputs.
By contrast, the Pulse is pure analogue, no Dac, no streamer.... that £1200 new prices covers power/pre section, phono stage and auto volume level and that's pretty much it. Even though it's quite old it still gives modern sub-2k integrateds a good run for its money.
In 2008, for the above reasons, it was a game changer around £1-2k price bracket.
It will never be looked at as classic and believe because so few have heard one. It is the Alfa Romeo of the hi-fi world: lots of plaudits but rarely do people actually put their hands in their pockets.
In a weird way I kinda like the niche-like aspect.
