Good day gents,
Thought I would share my musical adventures and reveal my findings after purchasing my current PMC Twenty5.23 speakers blind, driven by the mighty 272 partnered with the usual 250DR.
The PMCs are super revealing, extremely clean sounding, on the cooler side of neutral. A bit bright but things should improve once they play 24/7 for a while.
Not easy to drive, 8ohm / 86.5dB - I would say my 250DR would be the minimum these should be paired with.
They go deep (28Hz advertised) but due to limited volume, 28Hz sounds polite (but tuneful and fast) as expected. Plenty of base though, especially in a small room.
The finish quality is exquisite! They would feel at home in a Naim 500 series system.
They do excel in 2 areas: the stereo imaging is first class, they absolutely disappear to the point you don’t hear anything but the orchestra playing; secondly, they are ultra fast, stopping and restarting on a dime.
My first thoughts: very impressive but not exactly my kind of sound signature, perhaps too hi-fi for me. I love mellower speakers (Dynaudio springs to mind) even if they lack the stereo imaging or the insane level of transparency these PMC speakers exhibit.
Compared to my late Dynaudio Special 40, the PMC are way more transparent, significantly faster and image so much better. Compared to the PMCs, the Dyns are mellower and have more bass (albeit slower and a bit more bloated) however they come across as more balanced and are more forgiving in the way they present music. As a side note, the sound pressure on 50/100 volume (PMC connected) is about the same as 35/100 (with Dyns S40 connected).
My impression is PMC speakers would gel a bit better with a powerful valve amplifier however things could change significantly once the system has a chance to settle in (everything is burned in but today was a cold start after months in storage).
I should mention this is just a test run, making sure the speakers work. The final position would be in my very small carpeted home office (11 - 12 sqm), with better power cables and a Quadraspire.
Hope this helps.
