Realized just now that I know you from SBAF.  :thumb:

They already sound really, really great. The acoustics are outstanding, on a level I haven't experienced before. Sat here for four hours with goosebumps listening to things I love. I'm using some monoblock Rekkrs right now, did notice they started clipping when I got a bit overzealous... I probably need some new amps, maybe a pair of Gjallarhorns or something when I find the dosh.

Lol, yeah I lurk over there a bit every now and then. Definitely some fun DIY threads. But back to your Studios, you'll really do best with probably 20w for them if you listen at an enthusiastic volume. Remember, doubling power only gets +3db, so listening 6' away at 93db peak with a little extra headroom is already 16w. If you high pass them around 70-80hz then you'll free up a lot on these. I had mine with a hp filter and tried removing, but really they do sound better high-passed.

I think my plan is to sniff around for a used Bifrost 2 so I can eventually run balanced monoblock Gjallarhorns. I dunno if this is the best course of action, but I'm an almost two-decade long Schiit-head and it's hard to see beyond the trees.

Which caps did you use for your filter on the Studios? I made some recently for fun, they had a noticeable effect on my other speakers. I like huffing leaded solder so any excuse to fire up the iron is welcomed.

I had a BF2/64 for a little bit and ditched for a MHDT Labs Atlantis. The BF2/64 just sounded a little etched and overly analytical. While fun and very detailed, I couldn't listen to it long term. I even tried modding the opamps to Burson V6 but they didn't quite fit in the case all buttoned up. I would have had a giraffe in a convertible leaving the case open. :o

I'd say you'd be better off with an Aegir and a different dac if you were still set on Schiit amps. Now that you have very very detailed speakers, a BF2 may be a bit overkill.

For my HP filter, I used Miflex KPCU01 and fit the caps into my preamp case. My preamp has 2 outputs, so I just bridged the cap between 1 and 2 and had sub out on 1 and speakers out on 2. When I put them back, I'll snag another pair or the KPCU02 once I know the values I need for my pairing with my next amp build.

Dang. Good to know.

I'm still using the OG Modi Multibit. I put some OPA2156 opamps in there (as per that one hacking SBAF thread), but otherwise it has been my DAC for a long, long time. I did read that people were saying the 64 was overly analytical compared to the OG Bifrost 2, I had been thinking the OG would be the one, but now I don't know. The detail in the Studios shines through even on my setup, I can see why adding to that would be an issue. I never noticed how much tape hiss there is on Zeppelin recordings until today. Acoustic instruments are really a trip on these things, but, hmm, yeah, the setup, I really don't know what to do. Argh. I'll figure it out eventually.

Remember you're here forever?   :o

You might be happy to learn Schiit will be releasing their Gungnir 2 balanced DAC which will be a step up from Bifrost.  Or you could go for their Yggdrasil GS which is on closeout.  I got the latter and then fully upgraded it.  It is a fantastic dac!  I also use their OG Modi Multibit and MMB2 as well which is even better.

The new Saga 2 preamp has balanced outputs which will drive the pair of Gjallerhorns but no balanced inputs.  So many options!  I drive my X-SLS towers with a single Gjallerhorn in my living room system with Saga + and it sounds better than it has any right to!

Hmm, yes, maybe Gungnir 2 is the play.  :scratch:

I recently received my NX Studio kit and it came with the JPX caps.  However, after researching and reading this thread, I was able to source a pair of Miflex 0.1 uF caps for my tweeter circuit instead.  Wondering if it would be OK to use the JPX caps on the big cap in the woofer circuit like YEEEEGZ did?  Any downside?

No downside. Miflex to bypass on tweeter circuit will be awesome.

That's what I'm hoping!  So, it's OK to use the JPX caps as bypass on the woofer circuit main cap?

If you have the tiny red .1uF JB Caps... yep.  I think I have those on the JB JFX caps in the network for my Duette speakers now.  I have Duelund CAST-PIO .1uF on each of the Sonicaps in the tweeter network. 

I think the JB JFX caps (black caps) sound great on the woofer.  The fact that they are also inexpensive is very nice.

Yeah bypassing the large sonicap with a 0.1 bypass cap is fine. I'm not as familiar with the JPX sound but bypassing the main cap with a small cap of equal or better quality is always a perk.

I was able to source some Miflex .1uf bypass caps........this might seem like a silly questions...........The cap in the attached photo is bipolar, correct?

correct.

It's very rare to see polarized caps in passive speaker/audio capacitors, they are typically only used in electronics that run on DC current.

We typically recommend having components following the direction of the text; input before and output after.
But you wont hurt anything if you accidentally get one cap backwards.

All very interesting!
