Hi Audiofanboy, I was kind of curious about your current point of view.
It boils down to preference, incl. the setup your are using, and tube.
What we (all of us) could do in this thread are a few generalizations of the effect of strapping / non-strapping of heptodes in EF95 setting.
So, here are are some statements for discussion.
- Non-strapping, Gives most relaxed sound (as in least forward) and includes most ambience as well. Should work well with every heptode.
- 1/7, Includes more treble bias and can reveal more detail. Depending on tube you could loose depth of stage resulting in a more forward sound. A good way to make the tube "more engaging".
- 2/7, This is ambiguous for me. A total no go for the Tung Sol 6BE6 (bass crazy), not too much effect for the 6A6P, quite nice with the Amperex E91H - that's just me ;) (more treble, more engaging, more forward).
- EF91/92 (= 6/7 or 5/7), so far hardly useful strap for most tubes. For 6BE6, it yields more treble but lesser ambience and overall doesn't sound balanced. Having have said that, the 6A2P I have is quite bass heavy and with not too deep stage, so this strap actually could do something good.
Please respond everyone. I understand that it can take a while from now to reach final conclusion but once reached, I will add this to the table on p. 77.
Thanks hypnos1, no I am not in sound engineering. I am just trying to analyze and describe what I hear. I am used to analyze and explain other matters work wise.
Definition of focus from this post: Focus - A strong, precise sense of image projection.
So, when I write focus, I mean the quality of an image rendered in my head, coming from listening. If borders and shape of heads and instruments become better defined, then focus is improved. Think of lense focus. Your "loss of control" could also include instrument separation, which again can be a result of lesser focus and a narrower stage. Difficult to say. Definitely keep writing, you will notice that your listening analysis changes as your vocabulary changes, which helps to write your experience. Of course, we all do this for the pleasure of music and sound and that is in fact the most important thing. =)
Hi, I recently purchased a LD1+ for my SR325is's. The LD came with upgraded 6AK5W Siemens tubes (I wouldn't know the difference). I find my 325is's (for my tastes) need to be more upfront and engaging and have more clarity, detail and treble. I am totally new to this tube rolling, and have never opened my LD yet or heard any other tube amp ( only SS amps). From reading this particular post I see that STRAPPING + 1/7 opposed to NON- STRAPPING ( I assume) sounds like something I would definitley be interested in hearing. I would appreciate if you can tell me if I do this this with my LD1+ and with these tubes, also what STRAPPING is, and correct me if I'm wrong, but I believe from some diagrams I have seen, 1/7 refer to the pins on the tubes, which I think should be jumped together? Thank you.
