Having read through this thread several times now without adding any of my thoughts on the Allnic, and having been using one for a short while, I can not understand the OP's experience to be typical with this unit. To qualify, I have been using vinyl since the early 80's, and have used several high end phono amplifiers, either belonging to me here, or borrowed, including the likes of ASR, PASS, Clear audio, Concert Fidelity, Naim, Tri-chord, Audio Note (japan), Audio Note (UK).
Some of you will know that I deal with Concert Fidelity for the UK. My view is the Allnic beats the SPA-4c in terms of transparency, balance, timbre and certainly holographic imaging. The SPA-4c is a very good amplifier if it suits your cartridge's requirements, is MC only, and is all solid state, no tubes, uses very very rare Jfets which are in limited supply hence the small numbers of these units available. CF do not release a product without absolute completion of all attributes to their high standard, this they are famous for. But, the Allnic H3000, while being a totally different approach, acheives a very beautiful, detailed and enthralling sonic image, right there in front of you. Timbre is superb, flow is beautiful, there are no doubt's lingering.
As I have said, I do not understand the negative experience here, so to add balance to Lotus's input, (who I do not know btw, even though we are geographically very close) I agree with his input, I do not and have no intention of selling Allnic Audio equipment, but my thoughts are clear.
Anyone considering this unit should try to hear one and do not be put off by the one negative thread.
Best Regards,
Paul.
