Vinnie, please let me know if this higher-voltage version of the MINI would make practical sense as a replacement for the standard lead-acid battery power supply of a fully-outfitted Red Wine Audio Isabella. I realize that you have moved-on to bigger and better things, but I suspect the Isabella could be modified easily enough to accommodate a MINI-HV. The larger question is do you think there would be enough improvement in sound quality to merit such an investment?
Yes, the VR MINI (upcoming 24Vdc output version) would certainly be an improvement to the Red Wine Audio Isabella preamp and it should be able to be easily modified for this. Without trying it first, it is hard for me to quantify how much of an improvement and in what ways...
Is there a chance that a MINI-HV-powered Isabella could persuade me to want to reconsider that? Or would money be better spent just upgrading to a LIO?
I believe it would be much better spent on upgrading to LIO, and there many reasons for this
- LIO uses a signifcantly larger ultracapacitor power supply than the VR MINI, so it has much lower output impedance and much
higher current delivery.
- LIO's module platform is a lot more sophisticated, making future upgrades and add-ons very easy
- LIO's modules are all of much higher performance ( dac, phonostage, power amp, headphone amp, etc. - are all superior designs).
- Various linestage options (volume control / Tubestage) - all of which are higher performance than what we offered with RWA.
- Full-function remote (PWR on/off, Mute, Input select, volume control in discrete steps, balance control in discrete steps,
dac and phonostage controls).
- No need to be concerned about charging batteries, degraded performance over time as batteries age, or even replacing batteries
- No need to be concerned about play time limitations (LIO can be used 24/7/365 if you want).
- There are more exciting developments for LIO on the way, and it will continue to evolve because this flexibility was "designed into" LIO.
