Rowland vs Rowland

sirspeedy, is this new power supply similar to the outboard, switch mode unit used with the Model 10 and Model 12? Based on my experince woth the model 10, that upgrade is definitely something to consider.

I just bought the Rowland model 6. Although it is 10 years old is is by far the best amp I have owned. I am driving the new Von Scweikert VR-7SE. They replaced the Manley 250's and the difference was stunning. Unbelievable deep tight bass, better mids and highs. I have them plugged into the ac and haven't used the batteries yet. Should I consider the upgrade if its possible with this Model?

I own the model 9 with BPS and it has the batteries.
If you change it to the switch mode powersupply, do you get clean power?
With batteries you have clean power but what if the batteries are removed?
Greetings Bernhard.

Jeff Rowland assured me that the switch mode update was superior to the battery.He was right,IMO.I could not be happier.To me,the model 9 in this mode would be the best amp of all time.It IS DEFINITELY at least as quiet as the battery,and much more extended at the frequency extremes!!Much more dynamic as well!!

Due to scarcity,since the newer units are selling so well,you need to call Rowland(I don't know if the update is still on their web page)to ask for this FABULOUS update.Good luck to all!!
