Yes, it's an nice and informative article. Having a look at the specs of the 3 Square Audio Speakers tells me they have first order crossover but a sensitivity of only 85db. It's nice they're showing a NVA amp on one picture of their site but didn't you rant about the 87db of PMC?
So maybe it's not only the sensitivity making a speaker suitable for NVA. My mother's PMCs sound superb with AP20.

From the article: "Note that high sensitivity (above 90db) is not essential (unless you want to play at higher than average volumes with our lower powered amplifiers) - ease of drive is far more important."

I enjoy speakers with very high sensitivity (95db plus) but that is a case of personal preference rather than electrical compatibility. Tomasz has demonstrated to me that ease of drive is far more important for NVA. Of course, if you can have both, then great. It would be a pretty large speaker, though, and not everyone can (or wants to) accommodate.

iirc my complaint about PMC was the very complex 4th order crossover.

So I have to apologize for not reading the article attentive enough.

Currently have my arcam 2s playing. Have to say they sound the best I've heard since I have owned them, with this ap30 .
Have no idea of what kind of crossovers they have or even sensitivity. Amp seems happy though.
All wadding removed and rear port :evil: stuffed with straws(1998/9).

If I've got the right model...

8 element crossover, which is not overly complex, 8ohm nominal impedance, not dropping below 6.5 ohms. Look a sympathetic enough match.

His comments concur with my thoughts and what I would simply describe as faithfullness to the source, ie not adding or taking away. This has been my experience with the numerous upgrades and additions I made to the digital path this year, all of noticable benefit. Not forgetting parting with big bucks for the Mscaler in 2019 which took the music to a different level., prior to the P50SA/A80 and Cube 1s replacing 3s upgrades. With regard to his comments on vocals I found that TSCS (LS7) made the most difference. I think he is right in saying that NVA is for those who prefer to plug in and play rather than tinker about with different makes of components. To me the music is what it is all about and, although there have been changes to the digital path, it is NVA all the way from the DAC. I found his comments about listening for extended periods very timely. I had never played so much music in the four weeks prior to this one being alone in the house at the same time as the Covid restrictions. At no time was there the slightest hint of fatigue and albums I had not played in years took on a different more enjoyable prespective.

Rabski is of course mistaken when he describes the past as having limited options.

Great review by Rabski (I believe he's had some stick on here in the past) and his thoughts would be seconded by most NVA users. Hope this review can change some folks' ideas about NVA hifi.
