TM12, if you read me on this site, one thing you know is that I am a tube freak. That being said, not all equipment is good with all equipment. PSB Goldi speakers are difficult to drive. They are not tube friendly. That is an objective statement. It has nothing to do with them being a good design, or a poor design. They are just a 4 ohm load(many drivers are 4 ohm), and dip even lower in the lower frequencies, and also exhibit a pretty high phase angle. Getting away from simple(1st order) crossovers further burdens an amp. Some feel the paybacks are sonically worth it. In reality, Paul S. Barton(PSB), the designer and owner of the company is one of the best loudspeaker designers in the business(just look at all of his critically acclaimed designs). He is at the forefront of the Canadian loudspeaker phalanx, who have taken advantage of the National Testing Laboratory to develop themselves into some of the world's best speaker companies. In addition to PSB, there are Paradigm, Energy, and Coincident(which you and I both own), etc. Other PSB speakers are tube friendly(particularly their cheaper products). Easy to drive speakers can do things PSB cannot, AND vice versa. Listen to Goldi with the right ancillary equipment, and you may agree that they are a wonderful product. Kevin_Haskins, the dealer is in my area(Philadelphia, PA suburbs), and sells demos for about $1700. With some negotiation, I know you can do better, or even do well on a virgin pair.
