The SVS PC-4000 Subwoofer

Sometimes, the toughest part of adding a subwoofer to your stereo or theater system can be where to put it.

The SVS PC-4000 makes this easy; its 16-inch in diameter cylinder shape fittsin a corner perfectly. The PC-4000 is only available in black, and that’s my only complaint – white would disappear in the room better, and in the context of my 2.1 system with the powered Totem Kin Play speakers, you’d barely even know it was there. But that didn’t stop me from buying the review sample. We usually watch movies in the dark anyway so who cares?

Moving the PC-4000 out to our living room as the heart of a 5.1 system, featuring SVS Prime Elevation speakers, it works equally well, though in a quest for even more slam, I could fit two in this room. Because hey, you can’t get enough punch when watching action movies or playing games, can you? It has certainly made following this years’ Formula 1 season exciting. Watching the pack roar into turn one is way more engaging with all that low frequency energy. As is everything else.

SVS has built a tremendous reputation on high performance for the dollar and over the top customer service. The PC-4000 will no doubt, strengthen this reputation even further. While the shipping container looks rather imposing, once unboxed, the PC-4000 only weighs 93 pounds, so it should be easy to unpack and place with the help of a friend. Our more buff readers will be able to handle it solo, and our most buff readers will be able to play catch with it. Ha!

The proof is in the listening

The PC-4000 is easy to integrate into your system, once plugged in, download their app and adjust the necessary parameters. You can use the standard presets, or tweak to your heart’s content. The option of using the PC-4000 ported or plugging the three top firing ports makes fine tuning the sound to your room and system a snap. Deep in the corner of the bedroom system, plugging all three ports helped level out the corner gain in the room, and tweaking the EQ with the app takes things to perfection, not to mention perfect integration with my two main speakers. Once set up all the way, it was impossible to hear the subwoofer standing out.

Viewing the Queen biopic, Bohemian Rhapsody, with the PC-4000 turned off makes it so much more dramatic when the sub is engaged, showing off the full force of this legendary band in action. Awesome! For many, a pair of powered speakers utilizing the sub’s LFT channel might be all you need in a small room. In our 12 x 14 viewing room, we don’t even need to pop the popcorn, just putting the Orville Redenbacher bag on top of the PC-4000 and cranking it up makes the kernels spontaneously pop!

But seriously, having the level of bass extension and slam that the PC-4000 adds, makes you wonder how you ever did without it! Movies and music come alive and this sub is not a one note wonder. At the sound pressure levels that my small room accommodates, clipping or compression wasn’t ever part of the agenda. The level of detail and resolution it offers is tip top.
Moving the PC-4000 back to the living room, and taking advantage of the EQ presets earlier, it’s easier to achieve a bigger sonic picture. While we started our living room test with an Anthem MRX multichannel receiver and a set of SVS Prime Elevation speakers, this time around we made the PC-4000 part of a larger, more audiophile oriented 2.1 audio system with the PrimaLuna EVO400 preamplifier and EVO400 power amplifier with the SVS Prime Pinnacle floorstanding speakers. High res audio files were streamed with Qobuz and ROON via the dCS Bartok.

Thanks to the pluggable ports and the wide range of settings that the SVS app provides, you can easily optimize (and store) the PC-4000 to work with the LF requirements of a theater environment or a strictly music environment. Whether rocking out to AC/DC or listening to Stanley Clark playing acoustic bass, the PC-4000 digs down deep. In a larger room, it was easy to achieve near concert hall levels, and we could not drive the PC-4000 to clipping or exceed the woofers excursion levels. The heartbeat at the beginning of Pink Floyd’s Dark Side of the Moon, and Aphex Twin’s SYRO had the windows and the cabinets rattling!

Of course, the deeper your main speakers can go, the easier it will be to achieve perfect integration between sub and mains, yet trying the PC-4000 with a wide range of speakers large and small confirms this subwoofer has excellent upper bass response, with low coloration, making it easy to mate with a wide range of main speakers.

Easy to set up, easy to acquire

One of the smartest things they’ve done at SVS is to make it easy to finance their products. A set of speakers and a sub at $3,000 might not fit in your budget right now, but $125 a month is a lot easier to swallow for great music, gaming and movie sound. Putting it in perspective, that’s less than a foo foo coffee a day. I’d give that up in a heartbeat for rocking sound, how about you?

Those hungry for the full specification sheet, please click here, but SVS claims solid output down to about 16hz. Essentially the equivalent of their big, more traditionally shaped subs, with 1300 watts rms power on tap (close to 4000 watts peak) but in an easier to integrate form factor.

The SVS PC-4000 has no downside. It’s all good. And at $1,799, it fills a niche that no other subwoofer covers. Should you want/need a pair, the price drops to $1,600 for the second one – a nice touch.

If you need bass, and floor space is at a premium, the SVS PC-4000 is the way to go.

The Deep Core 1800 Power Conditioner

One of the things we always battle as audio enthusiasts is the effect that power has on our systems.

Whether you look at power as a giant pool that you tap into with your power cord or a stream that’s come a long way to get to you, there is still a fair amount of noise and audible grunge in the AC power that runs your audio system.

Again, some take the perspective that your amplifier’s power supply should effectively filter out whatever’s in the AC line. However, not all power supplies are created equal. Some are more effective than others – it’s no surprise that many of the world’s finest, (most expensive and heaviest,) almost always have massive power supplies, with gigantic mains transformers and banks of enormous filter capacitors.

Are you with me or against me?

If you’re of the mindset that power conditioning doesn’t matter or make a difference, there’s no point in reading any further. But if you’re with me, and you think that your HiFi system is like any other electromechanical device benefitting from fine-tuning, read on.

While the Deep Core is described as a power conditioner and can be used alone as a treatment option for your AC line, the Deep Core website suggests that for best results, it be used in front of your favorite power conditioner. Close listening to a few different conditioners from Clarus, ISO-TEK, Running Springs, and Torus confirm this, though in front of my PS Audio P15, (which actually regenerated a new AC signal) the Deep Core had no discernable effect. However, with all other passive conditioners at my disposal, this is a very worthwhile addition.

Adjusting the Deep Core in this manner is like fine-tuning VTA on a turntable when you hit the perfect spot, the music reaches a higher level of clarity, with more focus and transparency. Go slow, and you’ll know when you hit it.

This will depend on what you are starting with. In my main listening room, which has relatively new wires and a new AC panel, was not quite as grungy as in my living room, with the 60-year-old wiring. Interestingly, the PS Audio P15 in the studio registers about 1.8% distortion on the AC line, where the one in the house registers 3 – 4% on a regular. Garbage in, garbage out directly relates to how transparent your audio system will sound, because your amplifier at its lowest level is essentially modulating the AC power from the wall with a music signal. So the fewer artifacts in that carrier signal result in a more realistic presentation.

Bottom line, it works

I’ve always experienced power line conditioning products to have a more noticeable effect on vacuum tube gear than solid-state, and the Deep Core offers the same result. Interestingly enough, regardless of circuit topology in the source component, the Deep Core had a more profound effect on lower priced gear, no doubt because these components do not have as sophisticated power supplies as those further up the range.

Proof for the snubbing effect took no more than powering up my vintage Dynaco Stereo 70, which always makes a nasty click through the speakers. Via the Deep Core, tweeter destroying clicks are a thing of the past. My mid 80s vintage Linn LP-12 is guilty of the same offense. Again, its crimes pardoned with the Deep Core in place. If you happen to be riddled with noise in your environment from an older furnace or appliance somewhere, the Deep Core may be the only thing that cleanses the artifacts these things produce from your listening environment.

Power products are basic – you either hear the difference they make in your audio system or you don’t. Some change the sound without necessarily improving the presentation or revealing more musical detail.

After trying the Deep Core in a few different system configurations, it unmistakably does reveal more music with no shortcomings. Transients aren’t compromised, and the bottom end is not smeared – another sin that more than one power conditioner has committed during the audition process. Best of all, more musical detail is revealed, without the mid to high range becoming etched, harsh, or overemphasized. This is much harder than it sounds. That’s why most power products ultimately end up being unplugged in favor of the existing devil in the wall socket.

Trying not to go all Darth Vader on you, when you plug a Deep Core into your system, you should hear your soundstage get bigger, and thanks to the noise floor going down, things should sound slightly louder at the same volume level. As always, queue up a few tracks you know intimately. If you already have a power conditioner in your system, insert the Deep Core in front of the existing power conditioner, and as always, use the highest quality power cord between Deep Core and the wall socket.

I started with new and old acoustic tracks from Crosby, Stills and Nash, along with some of my favorite Kurt Vile tunes. Densely packed rock records still sound cleaner, but delicately layered vocal compositions are going to have you smiling faster. Those who’s tastes lean towards female vocal audiophile recordings will freak out instantly.

Once you’re really comfy with Deep Core, having gone back through a few cycles of auditioning it in and out of the system, get ready to fine-tune with the contour control. If you can enlist the help of a friend, this will make the process much more comfortable, because you can be sure of staying in relatively the same listening position. Going in about 5-degree increments slowly will take you to the sweet spot.

With a claimed capacity of 1800 watts, the average to slightly above average system will be good to go with a Deep Core. Plugging a gigantic, high current draw power amplifier will tax the Deep Core, and you will hear a flattening of musical transients at extreme volume. You’ll know when you’ve gone too far. Then you’ll have to decide which part of your system is more important to cleanse or perhaps invest in a second one. At $1,295 the Deep Core is by no means crazy money, and in the context of the improvements it makes, an excellent bargain.

Schiit Sol Cast Aluminum Turntable

Schiit's new Sol Cast Aluminum Turntable ($799) doesn't look like any other affordable turntable in the world. That's because it's designed to deliver the most amazing performance possible for the bucks, without regard to how it "should" look. If you want a normal-looking turntable, there are tons of choices. Schiit's Sol is the result of six years of R&D at Schiit Audio. Some may say we're just slow (and that may be true), but Sol also went through many iterations to reach its final form. That's how we landed on something completely unique, a true unconstrained unipivot design based on aluminum die castings, with not a piece of MDF or acrylic in sight. That's also how we decided to include an insane amount of high-end features, like on-the-fly adjustable VTA.
