Dynaco ST-70 and Magneplanar 1.6QR

Hi,

I just got into this with an entry level system consisting of Magnapan 1.6 and a dyna st 70. I love the sound, and they work fine together ,but I dont get enough gain out of the Dynaco. Should I be getting more?, if not, is there anything I can do, short of swithcing amps that would solve this issue?

If not , do you have any $1000 amp or less alternatives to recomend?

Very grateful for any advice in this matter.

Elartford,

Thanks again, your advice is really appreciated as this is a "on a budget mission" .. I found some 5503's at better prices than the 5502, is there any drawback or benefit for me to go with the 5503 vs the other? ,
also what do you think of the 555?

Lastly, here is a curious thing. Some time ago I emailed Jolida to ask if they had a tube amp that could drive the 1.6s./. they answered as below.

The 502B, 801 or the JD 1000A could easily drive them.

If you can get the 5503 for less than a 5502, do it. The amp doesn't mind having one channel unused. Also, if you ever get into multichannel sound, the 3 channels will be useful.

The 555 was very well regarded when it came out, but that's a long time ago. I think you would be better off with a current model.

Regarding Jolida...any amp will "drive" the MG 1.6, but not all will do it in a way that extracts the full capabilities of the speaker.

the input tubes of a ST-70 are 7199's

Andersd...David says that the Dynaco st-70 uses a tube type 7199, not the more common 12AX7 which I mentioned. I assume he is correct. Whatever the proper tube is, my point is that you should make sure you have the right kind plugged in. Many small dual triode tubes will work, sort of, when substituted, but parameters like gain will be affected.
