Experiences with Infinity products

I'm just curious if others have had the same sad experience, or if the unit I received was in the wrong hands before it ended up with me.
I got an Infinity Modulus subwoofer into the workshop and now I've been working on it for 4-5 weeks on/off. The fuses were blown, the output transistors were shorted (TIP35C/TIP36C), and some of the soldering around the PCB looks like something done in the dark by someone who is only used to industrial welding. My previous experiences with Infinity products are already not good, but can this really be the standard for Infinity products? Just the fact that the unit from factory use TIP35C/TIP36C output transistors (original according to the diagram/parts list) with 100 Volt Vceo for an output amplifier with a supply voltage of +/- 47-48 (= 96 Volts P-P)......??
Am I just unlucky or has anyone else had the same overall bad experience with Infinity?
 
It exudes high-flying design 🤣 🤣
