Balanced/Differential tube preamplifier recommendation?
First post here. Hello
I have a Wyred4Sound ST-500mkII class D power amplifier. I would like a balanced/differential tube preamplifier to go with it. Ideally I would spend less than $2000 on this preamp. A remote for power and volume control is a must for me.
I would like something that is true balanced, as my source is also true balanced
I have seen a few options, but most seem to be out of my price range, and to be an uneven match for a fairly affordable power amp like I have. Any suggestions? Thank you 🙂
@thought9 If its got a remote installed its all set to go- the handheld unit should be with it. Its an option- some people prefer the stepped volume control instead, which can't be motorized. |
@atmasphere alright, that makes sense. Why can't the existing attenuator be motorized? It is a resistor ladder? I know of plenty of preamps that can be controlled with a remote that use resistor ladders |
@thought9 The control has to have 4 decks because its controlling both the inverted and non-inverted phases of the signal. The stepped control has to not exceed a certain size. The switch we use can't handle the torque a motor will put on it due to the lack of a bushing in the design. |
bushing in the design. @atmasphere ok, I understand. In the units with a motorized attenuator, do you just use a regular potentiometer? |
@thought9 Yes, if a 4-dech control can be considered 'regular'. Turns out that due to a change we made in the volume taper about 8 years ago that the difference between the stepped control and the pot was mostly eliminated. |
