Which Harbeths?

Just to add on to the above excellent post by Arafiq. I understand the OP is disappointed with the hype surrounding the Harbeth and is not willing to try other amps. To reiterate, the Harbeth really come to their own with select amps as they sound horrible with the wrong amps. The SHL5 sounded like mud with the Audio Research LS-16mk2 / Plinius SA100 mk3 amp which I owned. Better results with Rega Elicit, Nait XS and couple more amps but still underwhelming and far from great. The LFD Zero LEIII transformed the speakers as the Harbeth sprung to life when driven by this little marvel. I eventually got something else as the LFD didn’t come with a remote and the build quality did not meet my expectations.

I owned the Mcintosh MC275 mk4 before and it sounded a little like mud to me with the overly warm syrupy sound. Although it may not be the model that the OP currently owns, I suspect it may be the bottleneck and culprit to the poor or dismal result. It is unfortunate that a different amp (or other Harbeth models) is not in consideration. For this reason it may not be appropriate to brush aside the Harbeth and regard it as an underwhelming or underperforming speaker if it’s not properly set up since it is not showing its true colors.

A point to note is the Harbeth does not provide the short term thrills in comparison to other more forward and brighter sounding speakers. The midrange and treble of the Harbeth are very natural and to me is superior to the Totem model 1 which I tried. I’m not sure how different is the Rainmaker though. When moving from the Harbeth, see if you would miss the more natural/neutral sound presentation of the Harbeth.

I’ve owned a few Harbeths including the C7,M30.1, P3ESR and the new P3ESR XD. The C7 was not my cup of tea. The P3ESR original model is the one that I always go back to ( I’ve owned 5 pairs). The shoe box size Harbeth disappear in my listening room like no other speaker that I have owned.
This guy likes them as much as I do!!

So feeling a bit stupid. I had only tried the Harbeths with them connected to the 4ohm taps on my McIntosh mc302. Swapped them to the 8ohm taps yesterday evening and a whole different speaker came to life. It’s different enough that I’m still taking it in, but almost a total 180. They went from borderline overly relaxed to almost a bit to energetic. The boogie factor is on a whole other level. The lack of clarity is more than gone. The bass is stronger and faster. They do seem almost a little aggressive even compared to the Totems.  Not per say bright but a little forward.  Part of this will be remedied when I swap out my dac. I’ve used a Musical Fidelity v90 dac for a while due to its smooth glare free sound. It recently went kaput, and I swapped in a Cambridge stream magic 6 to pull dac duties. The Cambridge is considerably bright and matter of fact. When I get the chance to replace it I think I’ll easily be able to tame the aggressiveness.  Overall they are very, very good now. I haven’t swapped back to the Totems yet to compare, but I have yet to be compelled to which was not the case before. I expect that the Totems will actually sound a little laid back in comparison now.  

I apologize for my criticisms, like I said feel a bit silly now. While they still might not be the best bang for your buck there price is very justified. My only supprise now is just how exciting and energetic they are now. Not sure how much of this is due to the XD update, but it’s overall very satisfying. My feet are moving and I’m singing along like a fool.  Which is what I’m in this hobby for. Again sorry for my inaccurate opinions. Still trying to understand how going from the 4ohm taps to the 8ohm taps did what it did to the extent that it did. I think I’m understanding that it increases the power to a 6ohm speaker compared to the 4ohm taps. This still doesn’t explain everything I’m hearing but some. Either way phew, what a difference. 

@yogiboy and @arafiq are good heads, well known participants, credible contributors here

i would just say here, that my experience is opposite from theirs, i prefer the compact 7 to the mon 30... it’s possible i hadn’t set up the mon 30s in their ideal setup (room and ancillaries) when i had a set, and likewise it might be that they did not either with their experience with the c7 - i have no doubt set up well, matched well in system and room, both can produce exemplary enthralling music

it just shows what one should expect in this hobby/pursuit, people have different tastes, experiences -- all worth sharing, no right or wrong

btw - both models are longstanding stalwarts in the harbeth line, both descendants of original bbc designs, both very good sellers, used and loved by many many all around the world

op

glad you found the right connection to your mac amp... and more glad that your enjoyment of the speakers has been taken up a notch

[please excuse my bad English]

I am, too, glad that you found the right connection to your Mc Intosh amp.

You mentioned the C7's are a bit forward now on the 8 Ohms output of the amplifier. A few points to try

1. you had removed the grilles => try to put them back. The grilles are part of the design loop, and John Atkinson did not removed them to measure the M30.2 Anniversary (which does not emphasize treble). The grilles off -> +1.5dB above 6KHz, IIRC.
2. Let them running in. A few weeks minimum is necessary. If the speakers are brand new, you can let them play at relatively low level when you are outside.
