System too bassy - Primaluna & Usher

Oops posted again by accident.

Ya I'm still not clear in what mattmiller is referring to. Although the biwiring seems like something that might help my boomy bass. There is a pair of kimber 8tc biwire banana plug wires for sale. He's asking $250. Good deal?

Biwiring does sound better in some situations, really depends on the amp and the crossovers in the spkrs, might be worth a try since the amp would be driving the bass and the high loads separately. Sorry, don't know about prices; Google some Kimber retailers?

A double-run would require 2 cables hooked up to same tap at the amp, then one cable runs to the tweeter, 2nd cable runs to the lower bass terminal. IMO, this probably would sound better than a single cable. But, you would need to buy 4 cables and be able to wire them both to the amp terminal, meaning using bare wire or spades.
I think this is what mattmiller meant.

PS...In both cases, you would be removing the stock jumpers on the speaker terminals which would be beneficial.

Biwire to resolve bass issues in this case seems like a total potshot and a bandaid at best.

"Biwire to resolve bass issues.."
Agree, Mapman. This is not the root of the problem; spkr placement and room acoustics are the most plausible cause.
But since the OP is looking for an upgrade in cables as well, some used Kimbers would improve definition in his spkrs.

Ya I totally agree with all of this. Based on my reading, it seems that an upgrade on the right type of cables (ones that are tighter and leaner) should help the situation, plus the bewiring would help too. I don't know anything about removing stock jumpers on the speaker terminals of my amp and all of that.

I changed the tubes which I'll get to in a min...

I agree that speaker placement and room acoustic treatment are my best, closest to source of problem, options (other then changing my amp or speakers). I just got the amp and really love the speakers so I'm leaving that as a last case scenario, but will try to avoid spending too much with an inevitable case of having to replace the amp. The speakers are already out pretty far from the wall without it looking pretty weird being half way in the room. So room treatment seems to be the next best thing. Although there is a possibility of me moving within a year.

So last night I switched out my primaluna EL34 power tubes for some svetlana EL34 WC tubes that came with my used purchase. I've only listened for a couple of hours. It seems that these are making the issue a bit worse, but that's not conclusive just yet. I need a bit more time to listen. Does this sound characteristic of these tubes?

PS. What are your collective thoughts on DNM resin and Coincident RCA's and how they're known for a more lean sound?
