Raul – I know you don’t like tubed phono stages. Yes, there are minuses, but plusses too. It is not like I go to friends places with solid-state stages and then when I get home I hear “fake” sound. I suggest we agree to disagree on that one. We agree on the tonearm, however. The Atlas + SME V combo has a low ca 7hz frequency. But is it an issue? I thought so, but was probably wrong. The real reason for the problem (woofer pumping) seems to be the diamond/cantilever connection gradually going bad, until the diamond got lose and then finally fell off. It happened after 12-1300 hours (I recalculated).
The Titan i has maybe 1800 hours, but happily, after a little adjustment, still runs fine, although a little worn-sounding. After more adjustments most of the worn sound (harshness and sibilants, muddy bass) was gone, and I was reminded of what a great cartridge the Titan i is. Going from the Clavis to the Titan was a larger step up, for me, than from Titan to Atlas. But this may also be due to a problem with the Clavis (riding too low). So yes, a retip and boron cantilever may be a good idea, when the Atlas has been fixed (for now, I need the Clavis as backup).
My SME V does not have mistracking issues. Mistracking occurs only when the vinyl groove is really bad. I did some testing of the arm bearing and found no problems. Maybe the Atlas tracks best, then Titan, and then Clavis – but they are quite similar. If the record is reasonably OK and the arm is fully adjusted, there are no tracking problems. This behavior is very different from the Souther/Clearaudio Triquartz parallel arm I had before, I never managed to get it to control the cartridge properly. With the SME V – no problem. The rigid construction, materials etc probably means that it can work well even if resonance is on the low side. The Titan, weighing ca 1 g less than the Atlas, is less challenging in this respect (and the Clavis, weighing even less). I can confirm that reducing effective tonearm mass by shifting the counterweight towards the arm base, taking off the upper bridge, and similar, does not have much impact on the resonance (testing with the HFN record). It became only a tiny bit higher, from maybe 7.1 hz to 7.2 if I remember right; it did not seem worth it.
