Interesting conversation, but I apologize to Marc for going off topic.
Marc, you show discipline and drive with your move out of central London to the chapel and then with your persistence, er resilience, and leaning in toward Zu. You have been teased and given much grief and I suspect felt some pain along the way. This struggle for success is surely shaping your views and you are better for it.
Haha Peter...you've noticed Lol.
The move out of here wasn't so much brave as trying a new adventure w the "missus", and in almost every respect it's been a success. From an audiophile POV it has given me room acoustics I was sorely lacking back in London.
Ironically horns like Bill's would probably have worked better in my London apartment, but that situation will never come to pass.
There had been times I'd been seriously tempted by Zu alternatives. After hearing the Cessaro Liszts horns in 2014 (but I really couldn't stretch to £70k), Graz Apogee Duettas (but I wasn't prepared to go megaWatts SS), a dalliance w AG Duos horns (but reservations on their ABS horns signature remained a major doubt).
And then the long term experiment of opening up my Zu sound so I maintained what appealed to me on day one while addressing those restrictions that were inhibiting on pure acoustic music like classical and jazz.
And for me pushing the envelope on setup, optimisation, tweaking etc has given me more personal satisfaction than the more simple option of just switching them out.
And as I've absorbed the sonic effects of dozens of classical gigs since we moved here, I have way more confidence my choices are good ones for the right reasons.
Now I'll freely admit the experience of Bill's horns is of a different order. But even here despite Bill's sound being so exemplary across the board, and my Zus are not the same, things now here are not so alien and inferior as they would have been pre-2015 and our move.
And so my spectrum personality takes great delight in comparing the changes I've wrought and sheer enjoyment I get from the Zus to 8 years of brickbats lobbed my way on this forum re championing Zu.
