Fra avsnittet "December 2005" har jeg klippet ut denne biten:
-- Two transformers stood apart from the others in how good they sounded. Of the top two, the Sowter 8055 is the winner, but not by a large margin over the second-best. Both this transformer and the Lundahl LL9206 (below) not only had great sound, but unlike the rest of the pack, only these two had focus and pacing and emotional involvement. The Sowter 8055 was the most fun to listen to, had the best soundstaging, the best pacing and slam. The Lundahl LL9206 trailed the Sowter 8055 by only a small margin. If the 8055 is a "100" then the LL9205 is a "90." I would personally be quite happy with either transformer, but in a direct comparison, the 8055 surpasses the Lundahl in every respect.
The rest of the transformers were not as good. None of them had any rhythm or pacing, or the emotionality of the 8055 or the LL9206. In this grouping were the Jensen JT-44K-DX, which sounds a bit coarser than the two best units; the Stevens & Billington TX-103, which has a bland unexciting sound; the Sowter 9570, which presented the tiredest-sounding rhythm sections; and the Bartolucci GIBA68, which is notable for having an odd rising frequency response being tilted up .5dB at 10kHz compared to 100Hz -- and it sounded that way, offering a lightweight, faster but thinner sound.
-- I did learn an interesting fact about loading MC cartridges when using MC transformers. There is a good-sounding way, and a great-sounding way to do it. I'm not going to write about it here, preferring to keep it as a trade secret, but I will use it in the WV preamps.
-- Another interesting tid-bit is that MC transformers, despite how complex they are, sound more alike than tubes, resistors, capacitors and wire. With those other parts, I expect to hear changes in tonal balance shifts, graininess, presence, bass artifacts, and edginess. But with the sole exception of the Bartolucci, which possesses a measurable and very audible frequency response aberration, these transformers sounded very, very alike in those areas. Where MC transformers differ seems to be primarily in terms of emotional involvement, presence, rhythm and pacing.
Forsterker mine inntrykk om LL9206 vs S&B TX-103, hørt i hhv CARY PH-302 og COLE (fra
www.diyhifisupply.com). Sistnevnte riktignok med høyere gain og langt lavere støygulv enn CARY, men dette er jo et resultat av konstruksjonen forøvrig.
