Correct. The TL-D1 will be mated with TRON Cantata SET 300B monoblocks*. If unsuccessful, I will not be selling my amps. But lets hold off on conjecture until the speakers, and system, has settled in.
Funny thing, the person who bought my Horning speakers has Tonian (PHY-HP version). His initial impression was the Horning mid/highs were not as good, but bass was better. His thought is that it's his amps; OTL and PP designs. The PHY-HP drivers prefer those amps whereas the Horning might be better suited with SET. This is only an initial impression based on very little listen time and quick set up. He mentioned trying an SET soon to hear for himself. Personally, I was surprised to hear his comment, especially about the Horning mids/highs. That is the Golden Ticket as reviewers have also noted. But as he said, it may be his amps are just not as well suited for this speaker as they are with the Tonian. Different full-range drivers, different and custom designs, mainly with Horning - hybrid.
What this comes down to though is does the sound satisfy my senses? If so, that's all that matters. There's always a level or so of compromise when changing gear and speakers. I've been fortunate enough over the years not to have had any major mismatches and always happy with those changes made. Being able to audition at home is key to that, but also pure luck. I do the research as best I can and make informative choices, which have resulted in an improvement each time. I also tend to keep with my choices for 3-5 years, sometimes longer. I'm not one to constantly change/upgrade my system. I do this for the music. The gear is just the means to that end. I can't be content if the sound is constantly being altered. Then you're consumed by that, it becomes obsessive. It's good to hear recordings in a different way, but it gets to a point of where does it end. I want to relax, enjoy the music, not play endless musical chairs with the gear.
