Are Atma-Sphere MP-1 and VSE RTP-3D similar?


Can anyone explain difference in topology between these two preamps? Look similar except for the dual volume control and tube comliment. I'm thinking of purchasing one of them.

Do any of you know how quiet the line section of the MP-1 is?

Though I don't think I've taken the volume control past 12 o'clock, the line section of the MP-1 Mk.III is very quiet.

To speak to Dgarretson's query, the Mk III's phono stage delivers approximately 60dB gain.

If you send me an e-mail, I can respond with a few photos of the inside of an MP-1.

Dracule1, I think you are wise to have the view that a manufacturer will have a 'colored view' of their equipment. I use the word 'biased' myself. For the record, many of the manufacturers that get into this industry are quite dedicated. I think you will find in a lot of cases that they will also say they have 'the best'. If they have integrity, they will also believe that they have the best.

IOW it does not matter if they **really have** the best, it does matter that **they think** they have the best, that way you know they are trying as hard as they can to do the best they can. For that reason, it is in fact useful to talk to manufacturers, as you can often find out information that is not in their brochures or on their websites. Sometimes the subtle details and lengths that a designer will go get a bit verbose and too wordy for advertising, but nonetheless can have significant impact on the performance of the equipment.

Of course, because of their 'biased' veiwpoint, you still have to take what they say with a a grain of salt :)
