I tweak sometimes. I've found I do it for the following reasons: 1) I've become aware of a potential low-/no-cost way to potentially address a particular situation (ex: improving dampening / isolation of components - a local business has leftover granite / marble pieces that one may pickup for free; placing them under / atop various components improved performance of various components. 2) My readings have brought my attention to a "moderately priced" product that
may enhance the performance / my enjoyment of a component or my system in general (ex: purchase of the following for my Rega P25 TT - J A Michell Tecno Arm Stub & Counterweight, and Pete Riggle VTAF; purchase of Walker SST to treat various system RCA and speaker connectors, IEC / power cord / tube prongs, etc.). 3) Tube rolling - some may feel this is not a tweak but a necessity - I also know it can get potentially expensive depending on what / how many tubes one wants to roll.
I don't look to spend much $ tweaking, esp. with a daughter who'll be attending college starting next year. I note there have been a couple times I've experienced major surprise at what I felt was a substantive sonic improvement for no or relatively little cash outlay. Regarding tube rolling, I've experienced substantive sound improvement with laying down some cash; however, there are some times I've wondered if I should have saved the $ and moved to another component. I also note I haven't done any tweaking for about a year, for whatever that's worth. That being said, I'm going to have dedicated lines run to my audio room...
