Rowland vs Rowland

Martinez,I,also have the 8t with the BPS.A fine amp.However I recently sent the BPS to Rowland,for the update,which was to take the BPS OUT and replace the BPS with the NEW Switch Mode Power Supply.No more battery to deal with!!

This meant that I sent "ONLY" the BPS chasis to Rowland(165 lbs),and it was returned with the all solid state Switch mode unit,installed.It had many advantages over the BPS.Firstly,it dropped the weight to 85 lbs.It NO LONGER needs any battery,which as you know re-charges and loses some energy over time.It DOUBLES your output power,from 100 watts per channel with the BPS,to 200 watts per channel,with the new Switch Mode power supply.

Also,believe me,it runs in pure DC mode and is QUIETER than the BPS.It IS a MAJOR improvement to the BPS.Much more dynamic and open sounding.I would not want any newer model over this upgrade,which was not very expensive.The 8t circuitry was fabulous,and IMO you cannot do better than this update,so save your money,over a new unit,and take your family on a nice vacation,with the savings,compared to selling,and buying new.You'll thank me.

Call Rowland for the pricing,and availability.Mine cost 1250.00 U.S. dollars,when it was done.Even if higher today,the performance was SO MUCH better,that it was worth double the price,to me.Good luck!!

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!!
