Dallas amp reviews1/17/2024 ![]() ![]() By 9am, birds were flash-mobbing my window, demanding suet. Clouds had been shedding wintery mix since daybreak. When the news broke in June that Audio Research had been acquired by AR Tube Audio Corporation, a privately owned corporation that includes Valerio Cora of Canadian loudspeaker manufacturer Acora Acoustics as a directorsee Industry Update in this issueI unboxed the I/50 and set it up in my listening room. However, with the uncertainty back then about the company's ownership, I postponed the review. I was planning to review the latest product from Audio Research, the I/50 integrated amplifier, which costs $5500, earlier this year. "Every now and again, when I want to be reminded of the magic it brings to my music, I set it up, plug in the tubes, and spend an evening spoiling my ears," I wrote for an article in Ken Kessler's 2020 book on the history of Audio Research. Four decades later, I still have that SP-10. "The SP-10 presented information in a more coherent, less distorted manner than any preamp I've tried," I wrote in the review, concluding that "the SP-10 made me realize how many good records I owned." I purchased the SP-10 and brought the preamplifier with me when I moved to the US. I reviewed this two-box, tubed preamplifier in the May 1984 issue of the English magazine Hi-Fi News & Record Review. Only built to order !

Ladies and gentlemen we proudly introduce the SoloDallas SD-50X. Exactly what Angus needed to express his signature style!Īmazingly few if any amp builders have had any interest in reproducing this amp of legendary proportions. These upgrades gave this classic a little more low-mid grind, faster attack and increased the output by about 5w. Most notably, KT66 power tubes were swapped with more reliable E元4 tubes, power transformer was upgraded to accommodate new power tubes and the GZ34 tube rectifier was exchanged for a solid state rectifier. This amp was basically a modified version of their original 45w model. Collectors refer to this model as the "Blackflag" due to the black screen printed logo next to the input. Photographic evidence and Fil's personal conversations with this legend's guitar tech and engineer have confirmed his amplifiers during that time were actually a rare 50w transitional model built during a short period from late 1967 to 1969. Even many of the guitar magazine writers got it wrong! Contrary to popular belief Angus wasn't using common amps by that lovely British company he helped introduce to a new generation. Our resident aficionado, Fil Olivieri discovered something about the amps Angus toured and recorded his band's biggest albums with that few guitarists know.
