Firstly cards on the table. I live in the sticks so auditioning kit is nigh impossible.
I've wound up with the M34i powered by a Rotel RA-1062, with a Squeezebox (FLAC) for source. I find that at background levels the sound is well balanced but as the volume increases, the mids seem to gain at a greater rate than the bass. By 9 o'clock on the Rotel, hard rock is almost unlistenable. I will cite Zep's "Whole Lotta Love" as an example. Everything kicks off nicely with the guitar riff & then the bass, followed by the vocals. Then the drums kick in & the first cymbal crash is (to me) over-emphasised. Then the power chords accompanying the chorus really grate like nails down a blackboard.
Another example is Floyd's "On The Run" from DSOTM. The hi-hat pattern that runs through that seems again over-emphasied to the point where it's dominating the whole track. Both of these examples are from FLACs ripped from the original red book CDs. I've conducted an A/B comparison between the CD & the FLAC & there's little if any difference. That seems to me to rule out a source problem.
I've also done a comparison between the M34i & M71i & the same kind of imbalance exists. So there's no fault on the drivers or crossovers.
I've had the M34i connected to a couple of Yamaha AV amps previously which exhibited similar but less defined symptoms. I put this down to short-comings in the AV amps which is why I bought the Rotel.
Finally I replaced the speaker cable, which was an eldery c.1.5mm with 4mm Van Damme HiFi Series. This made a surprising (to me) difference to the sound by evening out the bass between FLAC & MP3. The MP3 had a tendancy to boom but the apparent imbalance remains.
Last thing I did was download some AF test files which showed a couple of things. There seems to be a bass peak at around 69Hz & my elderly, battered ears can't hear anything over 12.5kHz. I couldn't discern any audile peaks in the mids but don't have an SPL meter. Obviously the wave pattern of a crashing cymbal is a whole lot more complex than than the perfectr sine wave of the test files.
Soooo - is it a characteristic of the Mission "sound" at volume (that is replicated with the M71i) that I'm not liking or something else?
Do I need a more laid back speaker? - a warmer amp? - both?
Environmental stuff:
My room is approx 4m x 6m with the speakers on the shorter wall.
They're approx 2m apart & 18cm from the rear wall, ports unbunged.
The room is carpeted (over concrete) with a couple of fabric sofas & large, glass patio doors.
The speakers ARE wired in phase.
