Well I am biased, although before deciding I home auditioned a dozen amps (inc a few all-in-ones) in the £3-8K range. I chose the excellent NAD Master Series M33. In fact I chose the earlier M32 over the other amps I tried, but upgraded when the M33 became available.Of course it’s subjective but maybe you could give some examples of these all-in-one wonders with streamer and phono.
I've had it for 3 years now and am well pleased with it. I don't use any analogue inputs so I can't comment on its phono abilities. The Stereophile review (written after my purchase) describes its features in detail. It was subsequently awarded Stereophile's Best Amplifier of the Year, Best Component of the Year and Editor's Choice of the Year. Not sure if any other product has ever picked up all 3.
It uses Purifi's Eigentakt amp module (built in house under license after tweaks by NAD, includes all the inputs and outputs you're likely to need and has Dirac Live available for those with complex speaker systems who can't get them properly set up without resorting to room correction DSP. I don't use it.
I also tried the Lyngdorf TDAI 3400 at a similar price. Sounded quite good but I preferred the NAD by a significant margin. It offers an excitement factor that I've rarely experienced elsewhere, but my speakers are a contributory factor too.
With a 10% dealer discount, a real bargain that I doubt can be matched for under £10K. I will try though (probably requiring a Hegel H390 or H590 and a Rose or similar streamer) as the outlay on my M33 is disproportionate to the investment in my speakers
