It was only a <A HREF="http://www.stereophile.com/musicintheround/music_in_the_round_37/index2… months ago</A> that I greeted Oppo Digital's BDP-83 universal Blu-ray player as a breakthrough consumer component, and it became a Runner-Up for <I>Stereophile</I>'s Budget Product of 2009. It now appears that Oppo is using the design as a base on which to develop similar and more advanced products, both for themselves and for a good many other manufacturers. Some may take exception to my use of the word <I>manufacturers</I>&#151;if it's an Oppo under the skin, what, precisely, are these other "manufacturers" contributing? Well, that's hardly a new question.

I was immensely impressed by the dCS Puccini SACD player and U-Clock when I reviewed the British combination <A HREF="http://www.stereophile.com/hirezplayers/dcs_puccini_sacd_playback_syste… December</A>. But as the physical discs becomes a legacy source of music, there was obviously a need for a related D/A product. SSI saw the public debut of the dCS Debussy ($10,999 with remote), shown off here by Tempo Marketing's John Quick. The Debussy basically combines the D/A, DSP, and analog board from the Puccini with the true asynchronous USB input topology from the U-Clock in a slim, attractive package. There are two AES/EBU and two S/PDIF inputs, as well as USB, and there is also a word-clock input to allow the Debussy to be controlled by an external master clock unit. Two digital filters are included, one a conventional symmetrical type, the other a variant of the increasingly popular minimum-phase "apodizing" type.

I have always been seduced by the silky sound of the true omnidirectional MBL upper-frequency drivers, and SSI was the first outing by the new North American distributor for the German brand, GTT Audio. The new MBL 126, shown in the photo and priced at $12,500/pair, is a smaller development of the 121, with side-firing 5" woofers complementing the midrange and HF drivers. The 126 was being demmed with the MBL preamp and monoblock power amps that so impressed Michael Fremer when he reviewed them a couple of years back, hooked up with Kubala-Sosna Elation series cables. Listening to a Reference Recordings classical orchestral disc, the sound was as expansive as I always hear from MBL's speakers.

Barrie, Ontario, about an hour's drive from Toronto, with a population of about 130, 000, is not a city that I associate with the design and manufacture of high performance audio equipment. It doesn't have even a single "real" audio store, just Best Buy, etc. But, as I found out at SSI 2010, Barrie is the home of McAlister Audio, maker of the OTL-195 monoblock amplifier and a prototype preamp. The designer is Peter McAlister, who produced his first prototype output-transformerless power amp ten years ago. The OTL-195 puts out 150W, and appears to be a very sophisticated design: fully balanced, able to drive 4 ohm loads, a circuit that tracks the signal level in the driver stage and modulates the control grids of output tubes, and various other circuit refinements. The OTL-195 is hand-built by Peter McAlister himself, and utilizes high-quality parts. The price is $8500/pair. As I mentioned in the blog posting below, the King Sound Prince IIs sounded great driven the McAlister OTL-195s.
