Having run an SB3 with a Russ Andrews Squeezepak PSU I can assure you that there is a vast difference in sound performance between the SB3 and my Transporter the Transporter wins hands down.
I believe it. I'm running a modified SB2. The Transporter borrowed a lot of ideas from the mods which were being performed on the SBs. But does it sound 5 times better, eg the Transporter costs 5x the SB...? If not, we are once again playing the game of rapidly diminishing returns which is what the SB is fighting against.
Like you though I do find the sound quality and pricing of the SB3 amassing likewise the same for the Transporter but I`m finding it hard to understand what more you can get for �3,000 and �9,000 apart from the name.
Well, I guess there is the potential for better components to make differences, eg Transporter, but now you are talking 15x - 45x the cost of an SB (ignoring the accompanying PC costs)... I doubt it sounds 15x-45x better...
And I guess there is some attempt at making the package easier to use. But again, is it worth the extra cost. Perhaps to some.
