Modwright SWL9.0 SE Tube Rolling


I'm using TungSol 5687 tubes as supplied by Modwright in my SWL9.0SE. They are very linear and extended with deep bass, however they have little midrange bloom.

Has anyone rolled other tubes in the SWL9.0SE? If so, would you please describe their tonal characteristics?

Can anyone recommend a source/s for the GE JAN 7044s? I had a bit of a troll around and didn't find any readily available.

Thanks
Hmm, thats interesting. After reading TVAD's posts I wasn't expecting much out of the 7044s. I wasn't going to post till I tried the Sylvanias (this weekend) but I have also found the 7044s to be a big improvement over the 5687s. I find the midrange to be alot meatier and I think the top end is a bit sweeter as well.

There definitely is a reduction in bass energy, still very tight and you can definitely hear it, just not quite as much slam. So that's a compromise but one I think I can live with.

Anyway, I'll let you know what I think of the Sylvanias next week.
Well, my intial impressions were that the GBs did some nice things tonally but seemed to have a negative impact on dynamics, leading edge and overall rhtyhm.

Now after listening to them a bit more I think they may be growing on me.

So, I'm going to leave them in for the rest of the week. Then Saturday I will do some side by side, listen, change back to the 7044s, listen to the same music again and try to come to a conclusion.

I think where I'm coming to is that they both sound much better then the stock 5687s but individually they each have some distinct qualities, so it's a matter of preferance. GB5687s more of a traditional tube sound, luscious midrange, sweeter highs. Jan 7044s more modern tube sound, better PRAT, more dynamic.

I'll let you know thoughts after the big shoot out on Saturday...............
