I am curious about what type of sound you are really looking for?
Despite the rave press surrounding the Halcro and Boulder electronics, many people, whose ears I trust, seem to share Rcprince's opinion. I hope to audition them in my own system at some point. In general, my understanding is that of the two, the Boulder is often considered somewhat more "musical." I am only familiar with the 18w Lamm and the 75w Tenor, but not any of the hybreds. I have not heard the Tenors with Rockports, but I have with Wilson X1-IIIs. I found them to have a beautiful, but somewhat classic tube midrange and lacking at the extremes compared to high powered SS amps or large VTLs. The Lamm is beautiful sounding, but I also believe they are somewhat restricted on top. To my surprise (having been devoted to tubes for years), I became captivated by the Levinson 33s. I found them to have the least sonic signature of the many amps I auditioned, and without the overly defined character I typically find to be ascribed to the Halcro and Boulder amps. I will also add that the 33s sounded considerably smoother and less SS than the 33H amps, both running at 220v. I cannot understand those who describe the 33H as the less powerful sonic equal to the 33. No comparison. Just my two-cents worth.
