It is a very old idea to say that higher power is required for good bass response. I do not think you will get any argument from anyone that increased power makes finding solutions to achieve a good bass response easier. |

Does it mean that any installation that used a low-powered SET to drive midbass shell be questioned by default? I wonder if it possible to developed some kind of “sewer pipe” index?

I agree that the output transformer is critical. If a low power DHT is to be used in such a DSET configuration, then the circuit must be optimized for the desired frequency response. It is the weakness of the DHT that the limitations of any full range amplifier circuit are revealed by low power output. |

Yes, but people mostly never think about DHT in context of DSET configuration. As much as I heard people talk about DHT then they always mean the full-range application. Did you ever hear someone refer for some kind of vintage or brand of 300B, 2A3 of 45 as “better for upperbass” or “better for upper mid range”? I did not. People mostly looking for a “full body” sound from a tube, I understand them but I do not know how critical it is if the DHT will ne use in DSET.

Is bass response the single most important thing? Some people think so, but I do not. |

We are not taking about bass response – the low-powered SETs have no bass. I was talking about midbass of the region the at the bottom of the “primary frequencies” – very important thing…
