The 300B amp that I am using has a magical euphoric (not euphonic) realism and I am looking for a linestage and phonostage with the same qualities. The amp is not euphonic, romantic, ‘golden’, ‘vintage,’ soft, fuzzy, or veiled. It is immediate, transparent and fast, yet beautiful, ‘human,’ and emotionally communicative. I have tried the […]

Admittedly, on a subject we know little about and in fact care even less about – but we respect the enthusiasm of others regarding the matter and so we’ll pass it on in that spirit. MORE
“I recently sold off my full Naim system (DAC/282/250/Hicap/NAPSC) and I have been enjoying the simplicity of my temp solution of the Nait 1 with Harbeth P3ESR, fed by the Mac Mini and Meridian Explorer DAC. Simple, lively, detailed, agile.. and only one hifi box with one plug in the wall! I am now enjoying […]
I’ve been looking hard and fast at my collection of 2000+ CD’s and 1200 vinyl albums with a view to stripping out what I don’t really need or want. If I purely focus on the items I really couldn’t live without under any circumstances, I’m down to 150 albums and 250 CD’s. Whilst I don’t […]
