Priorities for matching components to a turntable really boils down to the cartridge and phono stage. After that, any amplifier that fits your needs and ear will be fine. The Sugden is only a 30 watter, so you'd be scraping by with small inefficient bookshelf speakers. The Argon would be a slightly better choice in regard to efficiency, but Amphion still recommends between 50-150W. It's simply not easy to find an efficient small bookshelf. I guessing you could get by with the Sugden and your current HSU's though if that stated 92db rating is accurate. I'm sure the Sugden would be a sweet amp, but it will limit your future speaker choices significantly if you're committed to small bookshelf types.
