Integrated amp: Component weight

Maybe I missed it, but which Harbeth's?

Lot's of opinions about amps that will sound great with your Harbeth's, without knowing the model, or perhaps an assumption you have a version of the 40's given the stated power requirement of 200-300 wpc.

OP

200-300 wpc, 40lbs, SS, not Class D

Mono-blocks will divide the gross weight, but, it’s a near impossible ask.

That is why I said: sell those speakers (the source of the extra weight needed), get efficient speakers (which get moved once) and need much less power (smaller/lighter/less heat/less cost/more placement options).

that's why I called it a 'lifetime solution'. we get older, back/knees/shoulders fall apart.

Efficient enough, you could then try tubes. Mono-blocks probably to reduce weight.

You can get nearly everything you desire in a set of stacking separates

the naim nac 272 has a fantastic dac streamer headphone amp numerous analog and digital inputs.

combined with the high current naim nap250 it is 80 watts but very high current an drives Harbeths beautifully Naim’s punchy dynamic sound makes the Harbeths come alive.

and considering these pieces are separates the weight of each piece is manageable

and with  the newer naim 200 series dealers have this combo on sale for a liot less them what newer 200 series sells for.

@cundare2 - I'm in the same camp; bad back and can't lift heavy equipment up steps.

Not everyone's cup of tea, but I'm driving 86 dB sensitivity Bryston Mini T's with my McIntosh MA5300 integrated amp.  Here are some specs:

38 pounds unboxed.

Preamp out and Power Amp in jacks / home theater passthrough

6 analog inputs including MM phono and 1 pair of XLR balanced inputs

Class AB amplifier design

Built in "DA1" DAC with 6 digital inputs that can be upgraded/swapped out to McIntosh's DA2 since the onboard DAC is a module.

Headphone impedance is listed as 100 to 600 ohms.

$6,000 sticker, but you can buy them for less at dealers in person.

McIntosh MA5300

A drawback based on your requirements is that it's 160 watts at 4 ohms.

The Marantz PM 10S1 would fit your requirements. It weighs about 42 pounds And has 200 watts into 8ohms and 400 into 4ohms.  S/N ratio is 106db on lone has MC/MM phono stage, dua mono design, toroidal transformer, 5 RCA audio inputs plus 2 balanced XLR inputs. Can also be bi-amped. It’s also fully balanced. 
The price is about $5,000 

I do not have one, but saw one being used as a reference amp in a Magnolia hifi store and. It was easily able to power everthing from Magnaplans to big  B & W’s without breaking up. It is also a class AB amp. I wish you well in your search for the proper “power to weight” ratio as I recently purchased a 65 pound MICHI X3 to power my B&W 702 S2 Signatures with ease. A great tank of an integrated amp but to me a class A, AB unit should have sufficient heft t

Hegel H390 should fit the bill perfectly. Does all you want to do with the exception of HPs  isn’t TOO heavy and hits the power needs with no issue.

@soix: Thanks for a coherent respone. I need to handle:

- 3 or 4 analog sources

- drive 20ohm headphones (with or without an external HP amp

- drive an active or passive sub

- provide an HT-bypass input, preferably balanced

- deliver SQ in a class with Hegel, Ayre, etc., models in the same price range. A step above the HiFi Rose / Musical Fidelity MSx realm

@elliottbnewcombjr Uh, I have no idea what you’re talking about. I asked a completely different question -- are you in the right conversation?

Re: Coda, I have a lot of respect for the old Continuum product line, but it doesn’t look like the CSIB is a contender here, for more than one of the reasons already mentioned. Too bad, b/c it’s a nice box for the money.

+1 for the Coda CSiB ... but it weighs in at around 55 pounds

lifetime solution: sell those speakers, find some efficient ones to love.

Musical Fidelity M6si integrated amp

220 wpc, about 35 pounds and sounds wonderful on my PMC speakers. Class AB and should sound terrific with your Harbeth speakers. Its design is dual mono. I was so impressed with their sound quality, I purchased 2 of them.

See Upscale audio review of this amp link below

”Internally, the M6si is configured as 2 independent monobloc power amps with a separate pre amp. It is, in fact, a pre amp with 2 monobloc power amps that just happen to share the same casework.

The M6si has 220wpc. It has very low distortion, outstanding noise ratio and extremely flat frequency response. Its inputs are phono (MM/MC), 4 line level, 1 balanced XLR and 1 USB ‘B’ up to 24bit 96kHz asynchronous.

The M6 combination of high power, high current and extraordinary stability means that it can drive any loudspeaker with ease.”

If weight was not an issue I would suggest the Coda CSIB, It is class AB and can be biased to 3 different power outputs. 

So far, I've only found a few 15-35lb models that meet this initial filter, from sellers like Ayre, Devialet, & Bryston, and, surprisingly, even ARC.  However, there are connectivity & functionality issues that make these otherwise-terrific options a poor fit.

It’d be helpful to know what those connectivity and functionality issues are.
