Just like the brakes on your car whose performance is mandated by the condition of your suspension and tires, so too is a TT a 'system'.
A combination of parts working in harmony regardless of cost.
Sixty years of experience has taught me that the sum of the parts, not necessarily the parts themselves, need to be dialed in per mfg.'s specs, and lastly this system must be placed in a correct location in the listening room, free of vibration & feedback as possible.
A properly dialed in inexpensive system will inevitably sound better than an expensive mismatched one.
