In the original Pass B1 document, 2008, it reads that the B1 amp does 700kHz -3dB.
Is this bandwidth limited by the JFETs' bandwidth, or by huge power supply capacitors' bandwidth?
I notice that the original B1 does not have very small bypass caps in the power supply. So I am wondering how bandwidth will extend if very small film and ceramic bypass caps are used in the power supply (physically placed near the JFETs).
Note: My question is NOT about sonic effect (or sonic uselessness) of making bandwidth wider beyond 700kHz.

Toshiba 2SK170 spec: input capacitance 30pF.
30pF, 1kOhm RC low pass filter has -3dB point at 5MHz. Far above 700kHz.
