Why the facination with integrated amps?


I don’t get it. Is it the manufacturers spotting a trend with the tail wagging the dog or does a significant market segment truly prefer the idea of an integrated?
Pros;
Less space
One less set of IC’s
In theory-one less chassis/case to pay for
Shorter signal paths possible
Can combine transformer/cap function
Cons;
Power supply interference/spuriae
Reduced Flexibility-can’t switch amp or preamp as easily or go to monoblocs
Less resonance control
Long history of lesser performance per measurements and long-term subjective listening
Less resale value if it turns out to be a fad
Less liklihood of an extremely high performing active preamp

I freely admit I am a skeptic. The industry-like so many others-looks for new market niches to move product. 
FWIW, the only integrateds I myself would care to audition would be from Esoteric and Luxman who have a long history of designing no-compromise (low-compromise) high-end integrateds.

My system configuration is:

·       T+A PV3000HV Integrated

·       T+A MP3000HV Multi Source Player

·       Bryston BDP-3 Digital Music Player w/ Samsung 860 PRO 2TB 2.5 Inch SATA III Internal SSD

·       Music Hall MMF-9.1 Turntable (with the Goldring Eroica LX cartridge)

·       Legacy Audio Focus SE Loudspeakers (bi-wired)

I have two short (20’) dedicated 30 amp 10 gauge service lines (US made Southwire Romex - 😊) from the panel for this system. The integrated amp is plugged directly into the wall and the other components going to a Furman PST-8D Digital Power Station, the MP3000HV two powers cables - one for the digital side and one for the analog side, I spit between each of the PST-8D isolated banks.

Surge protection:

·       Leviton 20/240-Volt 200 Amp Outdoor Rated Meter Socket Surge Arrester

·       Eaton CHSPT2ULTRA Breaker box surge protection

I am pretty light vinyl user so I went a bit middle of the road with a turntable. The BDP-3 is connected to the MP3000HV via AES/EBU – I think sound quality is a bit better than going USB.


AES/EBU better than USB?  Really?  AES/EBU is just SPDIF on a balanced physical layer, with all the synchronous issues (clock is least common denominator) rather than USB whcih allows, no, demands re-clocking - its asynchronous. Actually its not re-clocking, its clocking, period. That means your DAC determines the timing, and timing + voltage (DAC'd output) = slope = frequency = music, to over-simplify.  So that's almost astonishing, unless your digital source has God;s own clock.
You hear what you hear, and you may be right in this instance, but i'd be asking myself "why?" and "what's wrong with the other interface?"

When "Hi-FI" gained popularity at the dawn of the "50's, the affordable amps were Integrated - Bell, Brook, Bogen,Grommes, etc.  No frills. Then Mac, H.H.Scott, Marantz, Fisher, Quad brought increasing levels of
sophistication and fidelity - at a cost. Nowadays, many of us don't feel
the need for flexibility options the Separates offered. Us old-timers
remember choices for distinct recording curves: AES, Decca, RCA
(RIAA), LP, 78", etc. along with and the introduction of a "loudness" control - these and several other control options, along with demonstratively better audio are what set Separates on their elevatedstatus back then.
That's apparently changing, and perhaps for the better, for the reasons others have mentioned.  For my part. I enjoy the flexibility and audio offered by my fully-rehabbed MC 34 and M 2570 (End of the G.Gow era and his sound at Mac).
Maybe I'm simply too old and can't hear anything better!

But, hey - it's all about what YOU think you hear, isn't it?

Had a MC 6100 integrated amp 40 years ago none since then.If you love integrated amp jump on one asap!!
