Possibly I'm just confused about the meaning of words being used here. My home setup could sometimes be called "warm" but no one would ever call it "fuzzy" or "blurry". I use a anvil turntables deck with a ZYX mc cart, through a step up transformer, a musical fidelity phono preamp, a homemade preamp based on the white cathode follower topology (tubes), and a homebilt single ended triode amp. These feed to a homemade set of full range speakers (quadratic taper mass loaded back horns). I haven't measured it, but using computer models I'm probably around 10% total harmonic distortion. This would be totally unacceptable for modern transistor based gear. It can be light on bass, as the -3db point is around 50Hz, but for most music it's ok. For reference the open E on a string bass is 41Hz. The lowest note of an orchestra is around 28Hz, the low Bb of the contrabassoon. I have a subwoofer (tapped horn topology) that goes down to 28Hz, but switching it on requires turning on the crossover and most music sounds better without it. As an aside, this is probably because for very low notes we hear the second harmonic predominantly, not the fundamental (I.e. an open E will sound most at 82Hz, not at the fundamental tone of 41Hz). In any case, it sounds really, really good. Sometimes warm, but precise and clear, never fuzzy or blurry.
I designed everything to work together, and it's intended to be as simple as possible. There are no crossovers, I'm using tubes to make voltage (which they are still unmatched as a device to make lots of clean voltage gain) and then transformers to make sufficient current. It makes about 8W of power, but I have efficient speakers and virtually no losses. It's not the best one could possibly do, but it's good, and I'm not the only one who thinks so.
