This circuit is not for a standard audio application. The input signal is band-limited <1 kHz and is pulsed (or gated) so average power is low although instantaneous power will be high. Pulses are about 1/2 second duration and duty cycle is about 1%. It needs to be quite small (< 12 sq. in.) and weigh less than 1 lb.

3.2 Transimpedance Amplifier Circuit Design Usually ultra-high performance audio DACs are differential current output, so a transimpedance amplifier is required to convert the current to voltage. Some design rules for the I/V transimpedance amplifier: 1. The amplifier will have ultra-low noise and distortion to achieve excellent system SNR, THD+N, and

https://audioxpress.com/article/t-reg-a-high-voltage-regulator-for-tube-amps
Tube amplifiers can benefit from regulated and stabilized power supplies, especially sensitive preamplifier stages, but also (single-ended) power amps. But traditional high-voltage regulators add several extra tubes, complexity, and power losses, while good performance is not easy to obtain. This article, published in audioXpress, April 2009, describes a novel …

For example, if an amplifier is to produce 100 watts into a 4 ohm speaker, we need 20 volts RMS. This implies that we need about +/-28 volts. (20 volts R.M.S. = 28.28 volts peak). We call that the "rail" voltage. Since the amplifier's output transistors cannot pull all the way up to this rail, we actually need a slightly higher voltage.
