WTB: speaker tap cables for 650

Anyone with 650 to XLR and XLR to banana so I can use speaker amps?

Any reputable cable company that can do this without megabucks?

 

Um...what kind of amp are you using here? Do not blow up those 650's!

 

Oh yeah you might be right. I wanted to use firstwatt sit3 would that work? Kinda new to this

I'm not seeing banana to 4-pin XLR up there now, but he's sold them in the past; might also be up on his ebay store. Maybe shoot e-mail to him?

 

I have an extra xlr to banana cable I'll give you if you want it. Just shoot me a PM

 

I have a SIT-3. I don't use for headphones, but pulled it out this morning to give you some thoughts. Most importantly, the SIT-3 seems to work best with 6-8 ohm speakers. See p.2 of Herb Reichert's review:

"In the vestibule of Nelson Pass's house was a pair of red Zu Audio Druid loudspeakers tht Pass had brought back from the 2018 Burning Amp Festival. Pass knows Sean Casey, Zu's founder and engineer, and at audio shows Casey makes great sounds with one or another of his speaker designs driven by Pass Labs amps. I therefore assumed that the SIT-3 would drive my Zu Soul Supremes with easy-rolling ease and super dynamics. I was wrong. The Soul Supremes, specified as having a sensitivity of 101dB/W/m and a nominal impedance of 16 ohms, sounded mushy and muffled with the First Watt. Not dynamic. My friend Sphere was with me, and we were dumbfounded. As we listened, Sphere sent Pass an e-mail. Right away came the reply: "Tell Herb to shunt a 16-ohm/10W resistor across the Souls' binding posts." Which I did.

The shunt resistors accomplished several things. Primarily, they reduced the Souls' nominal impedance to about 8 ohms, and their minimum impedance to closer to 4 ohms. They also lowered the impedance peaks and reduced the phase shift. Most important, the sound changed from mushy and muffled to vivid, clear, and crisply detailed. The simple addition of a resistor had allowed the Soul Supremes to deliver a charming, relaxed, naturally focused sound that satisfied with all types of music."

I listened to two albums with the HE-6SE and the HD650 from the SIT-3, and used 10R, 5R and no resistors. All sounded fine but the resisters improved the bass on both headphones. I preferred both headphones with other amps but both are doable, and no risk of blowing the HD650 (start the volume at zero obviously). Since you have already, you may as well try it out.

Zu Audio has resistors that are convenient to use across the binding posts:

Cool thanks, send me a pm , would be curious to hear about your sit3 impression
