Nandric, come on I don't need your chiding; what do you think the IMHO in my post means? You are free to disagree but spare me the drama.
As to the reason that IMHO the Rega is a poor choice, the rather over controlled upper midrange in the RB-300 is a bad match to the conceit in the upper bass/lower midrange of the TD150/160 series, leading to an overall dark sound leading sparkle, again IMHO. I-M-H-O. Additionally, the arm is too heavy for the standard springs leading to a lower primary resonance in the suspension and a further increase in the loseness in the same upper bass-lower midrange region. Again IMHO. I-M-H-O. I-M-H-O. IMHO.
And completely agree with Jeremy72 that many of the arms that I mentioned are not compatible with medium/low and low compliance cartridges, however very few arms are compatible with all compliances of cartridge and I don't think that it is justified putting an arm on the table that is too heavy for the suspension just to match a cartridge. Usually the cartridge is purchased to match the arm, not the other way around. The RB300 is also not compatible with many modern cartridges, so I am not sure of the point here, IMHO. I-M-H-O. IMHO. IIIMMMHHHOOO.
