Philips-PD9000-Portable-Compatible-inlcluded

What can I say, this unit runs almost continuously in the summer, I turn it off in the winter. It's running under a 6 ohm load which is really pushing it. I have 3 pairs of outdoor speakers with separate impedence matching volume controls, that sort of help with the impedence, and this thing has held up really well. If I crank the volume too high (like really loud) due to the low impedence it will go into protection, but that's not the fault of the unit, it's rated at 8 ohms.

So, in all this has been a great purchase.

I have what appears to be the BESTBUY version of this receiver, the Insignia NS-R2000. It is identical in all respects, except for the name, and the remote control even works with the Sherwood. So, with that in mind, I replaced a Sherwood 4105 with this unit. I have 3 pairs of speakers connected to impedence matching transformer volume controls. 2 pair are 4 ohms and 1 pair is 8 ohms. The transformers are supposed to present an 8+ ohm impedence to the receiver.

With the 4105 the receiver would go into protection if I put the volume control on -50. I have now run the same speaker configuration with the 4109 for 18 hours and it has worked fine.

In most other respects, this is very similar to the 4105. Exceptions are that the 4109 has much better speaker binding posts and the remote control has bass and treble controls. The 4105 has satisfactory spring loaded speaker connectors and lacks the tone controls on the remote. The 4109 also has a Phono input.

I would say that all of the comments on the 4105 apply to this unit as well. I seems underpowered for a 100w/channel amp. But I am driving outdoor speakers and I don't want them to get very loud anyway.
