My understanding after reading your feedback is that I might get a sound that pulls a smile out of my face with a RP3 + MP110/Elys2 and one of the three phono preamps I'm planning to get. Better or not than CDs is not the right question. It will be a different kind of sound. I can understand this since I have a basic TT now that somehow and very vaguely shows this characteristic.
I have hundreds of LPs and want to make it my main source of music (I have way more LPs than CDs). This is the reason why I'm investing on a decent TT. Spending over 1000$ is a lot for my financial situation, it may be nothing in the HiFi ground but my original question was only aimed at finding out if the equipment I mentioned (or similars) could deliver something we can call good sound quality.
I think the answer is yes. I think I will enjoy the ride!
With my current TT I enjoy more some very few records than their digital versions (Dire Straits, Kind of Blue, Pear Jam's Vs). But that is about how far it goes. For everything else I have, CDs out perform my current TT by far. There is just no point of comparison. I assume there must be a sound quality improvement between a 100$ TT and a 1200$.
