The best of the rest. My spare-gear system.

With a serious case of frigid weather induced cabin fever, this morning I decided to take the best of my spare gear and put it in my bedroom. This also happened because I didn't feel like carrying the VAC PA 100/100 upstairs.

So in place of the amazing but 15wpc Leben CS-300x, running off of my BlueSound Vault2 as a source, underpowering my Elac UB-5s.... I ended up with this.

All of which needs a good dusting, as the DAC and preamp have been unused for many months if not a year.

The signal begins with the aforementioned BlueSound Vault2, a streaming device/music server. It's loaded with several hundred CDs and counting, and also streams Tidal.

From there via Coax we get to the BMC PureDAC, which is also a very good balanced headphone amplifier and digital preamp with well handled volume control.

After that, we get to the Bel Canto SEP-2 preamp. From the owner's manual:

"The SEP2 gain stage is a zero loop-feedback single-ended triode design. This gain stage provides high gain and low noise with very low distortion and low output impedance for load drive. It uses a pair of dual 6DJ8/6922 triodes having long life and ready availability. The output is coupled through a selected Polypropylene film and foil capacitor...."

Blah blah blah inverts output so switch the speaker outputs on the amp.

After that comes the gigantic and gigantic sounding VAC PA 100/100, which sounds better with an active tube line stage ahead of it than an all-warts-revealed transformer volume control. And it grabs the Elacs and throws then around quite nicely. "Please show us some mercy!" they say.

Which is to say, the Speakers are the Elac Uni-Fi UB5s, finally on proper stands dug out from the wilds of the basement with only a sore back and a great improvement in sound to show for it.

The last little bit? Audeze LCD-2 headphones.

It's all just warming up, but man..it sounds awesome.

The big outstanding question is whether or not I need the preamp at all. The DAC is a preamp, as long as I'm just running digital stuff. And that's what I'm doing right now. I have the Vault and the TV hooked up to it, coax and TOSlink respectively. I watch a lot of movies and wanted a much bigger sound :)
 
Also, the ELACS. What can I say? They are just ridiculously good for their price and a good deal beyond, and that they can be had on sale occasionally for $350 is just bananas. They are, here, keeping up with some fairly top-flight and well-respected tube gear. If they have a fault its that bass can get loose and boomy towards the low low notes at high volume. Beyond that? They're just fantastic. The very heavy Target four post stands here are really helping them out. Prior, they were sitting on the white console on foam monitor desk-mount pads. Not bad but it doesn't let them shine their best. The Elacs are good speakers that just keep getting better as better gear is thrown at them. I think, here, I've reached their limits but this is a system that wouldn't be out of place powering esoteric high end floor standing speakers.
 
This looks very cool John!
Thank you, Bill. This is fun. It's nice having the main setup taken care of, to a point where I'm so content with it that I can just play around now with all the odds and ends collected along the way towards that end. If this all had sounded daft on the Elacs I'd been ok with that, because it's gear that was acquired for the main system but didn't make the cut ultimately. But it doesn't sound bad at all, it sounds fun!

I may bug you at some point about DSD streaming, as this DAC can handle DSD, at least to 128, and there's a good USB input on the DAC.
 
Slight modification...since I'm only running digital sources right now, I took out the Bel Canto preamp, and am using the BMC PureDAC to control volume. It actually sounds better without the tube pre in line... the VAC can get kind of dark sounding, and the Bel Canto isn't at all a bright preamp. Sorry, Bel Canto, I know you thought today was the day... back to the rarely used upstairs system with you!
 
Another expedition to the basement resulted in me finding the large spikes for the speaker stands. The boominess in the bass is less of a problem now. My lively wooden floors were playing along, I think.
 
And if anybody cares, the speaker cables are old Kimber 8tc, COAX and RCAs are audioquest. Power cords are currently just thick black whatevers, I'll have to fish out some of my fancy ones and see if I can cram them behind the cabinet.
 
So the VAC "Vintage" line stage, which I think has been updated to MKIII, is playing along nicely. It doesn't sound as good played really loudly as the BMC does without it, but it fills out the sound a bit at lower listening levels which is probably good for a bedroom system. Undecided. But...it does have a phono stage which brings up an interesting option...
 
Nice SL-10.

Isn't fun when you "discover" components previously tucked away and forgotten? ;)

Like Christmas all over again. :)
 
I could theoretically hook both SL-10s up but I don't really know where the other would go. There's two phono inputs on the VAC. The one in there now has an Ortofon OM-30p on it, the other has a Stanton L727.

I'm now sitting here rolling tubes in the VAC. Debating between a Siemens and Mullard 12au7 in the line stage. The more significant tubes in the phono stage got a Genalex Gold Lion and a Telefunken 12ax7, after taking out some Heath/Mullard ones. Too thick. Too much of a gooey good thing.

Enjoying the audio voyage, gives me ideas for the bedroom system too! Only one thing; are the spikes digging into the wood floors (ouch)? I imagine they help ground the sound though.
 
I own that same preamp in a Mk. II version.
This is a Mk. II as well, but I recall the previous owner having sent it to VAC to be upgraded. I'll have to look through my messages with him. Either way it's a very nice preamplifier. I've hardly ever used the phono stage so this is fun. I always used my Juicy Music Tercel II with it, but I don't have anywhere to put that here.
