It certainly looks like there is some interest in a low-powered, Class A output stage. This is something that I will definitely look into in the next
3. Quality volume control?
The LIO RVC (resistor volume control) module is very high quality, offering 64 steps of attenuation via discrete Vishay/Dale resistors that are matched to 0.5% tolerance. The quality is definitely on par with stepped attenuators from Goldpoint / DACT (with with many more steps for finer attenuation levels). And since we can individually control the volume of both channels, the LIO RVC has a 'balance control' without adding any additional circuitry. It simply offsets one channel by 1, 2, 3.... 12 steps (approx. 1dB steps), all easy controlled via the included remote control handset.
The LIO AVC (autoformer volume control) is premium volume control option (but much larger because of the use of 1 autoformer per channel, so it takes up the location of the optional LIO TUBESTAGE module). LIO AVC has the same fine control (64 steps, and balance control) as LIO RVC above.
1. Variable xover for outputs and inputs?
Yes - I'll be looking into such solutions for this as well in 2015.
Thanks for asking for people's options also. Much appreciated.
Thank YOU for all your feedback! I want to look into offering options that our customers / potential customers would really like to see in the LIO - and I greatly appreciate all your feedback. I can't promise that I will make all suggestions into a reality, but I do promise to consider them all.
