FWIW, I bought the Denon AVR-S730H and Kef Q150s at accessories4less.com for a total of $645.00 and everything works great. Both refurbs and speakers had an additional 10% off which is nice when they cost $450. Really nice sound and I'm pretty amazed at the bass coming out of these speakers.

So I own a Schiit Gungnir Multibit (DAC) + Mjolnir 2 (headphone amp) that I used to combine with some Audeze LCD-XC headphones. I no longer work in a private office where I could leave them setup, so they have been sitting in a box.

For home usage, I have a pair of Polk LS70s (1994 represent) that I used to run from a meh Pioneer VSX-816 receiver. And now I have a high-end DAC sitting in a box...

I'm thinking of getting 2 Schiit Vidars in monoblock config to run balanced from the output of the DAC, but I have no volume control in this setup. I see a few options:

1. Buy the Schiit Freya which is $699 for essentially a balanced, relay-based stepped volume attenuator as I have no interest in adding tube sound.
2. Build my own balanced relay-based stepped volume attenuator (fun, but time consuming). Maybe other people would buy it, who knows?
3. Build a protection system that clamps the output of the DAC at dangerous volume levels and depend on digital volume control. Probably use an ADC + microcontroller-controlled relay to act as the fuse.

Without analog volume control in line and no protection, I run the danger of my PC / Apple TV / whatever outputting a signal that will dump nearly a kilowatt of power into speakers. The relay volume control should be sonically transparent while digital volume control should arguably be bit-perfect since it just scales PCM values.

Thoughts? There has to be someone selling a relay-based stepped attenuator volume control for a few hundred; I've seen a few kits but they seem designed for integration into a cabinet.

Either way I will likely end up building a supervisory circuit to control power to the Vidars since their idle draw (60W each reportedly) is stupid high and I can let the first few seconds / minutes of music "suffer" from the bias supplies and transistors warming up and hitting steady-state. Wish they had a trigger input or similar.

If you must monoblock maybe play with bridgeable pro amps before you spend an additional $1400 with memejoke audio, a lot of them have volume limiting and low power standby and other useful features built in. If it was me I'd just sell everything and get a really good stereo integrated amp or receiver like the NAD C 388 but that doesn't sound like what you're looking for.

Part of it may be sunk cost I suppose; the Gungnir combo did great with the headphones. Schiit doesn’t seem to be particularly with the times in some areas or they are genius marketers to greybeards (surface mount assembly is INNOVATIVE!). Their analog is pretty good but the digital stuff they do reeks of greybeard digital engineering (but then they do the DSP-based DACs, so...)

Not opposed to looking at other stuff; seems like the NAD is Class D but packs a ton of simplicity like HDMI passthrough into a compact box.

What’s the general goon opinion on Schiit stuff? I suppose some people have posted about it in the headphones thread also.

I'm mostly just saying if you want to stay with the "separate components for everything" route pro gear is a better value. I don't have strong feelings about Schiit stuff, just a general sense that it's not that great a value. They're super good at marketing and building a slippery upgrade slope for their gear, though. Any amp from Crown, QSC or even Behringer at the $300 level will have gobs of power and not run at 35W in standby.

If you’re set on separates I would look at NAD power amps second hand honestly. Power amps are generally repairable and their 80s stuff is obnoxiously powerful for transients and dynamic power. The 2400 I picked up for 180 bucks has 100 wpc but it is the meatiest 100 Watts I’ve ever encountered. I think peaks are something close to 400 wpc into 4 ohms. Double that if you’re bridging a pair of them.

NAD has a reputation among lunatic audiophiles as being “mid-fi” and a little unreliable but I’ve never had a problem with it. (I’ve got....5 pieces? Two receivers (740 and 7100) power amp (2400) and two CD players (542 and 5000) the only thing that needed fixing on any was some deoxit on the power knob On the 7100 and a laser assembly on the 542 (8 dollars from China and 15 minutes of work.

**oh yeah, only the very new NAD stuff is class D. All the 80s/90s/00s stuff is class A/B

I've done too much reading on the subject lately and reframed my brain into thinking "If you spend around $1400-$1500, what can you get?" (partially because of the push-back in this thread which is good). Dropping the idea of 2x Vidars because 1) that's $1400, 2) don't need the power, 3) got sucked in by the "KEEP EVERYTHING BALANCED INTERCONNECT" trap.

I'm biased towards Class AB amps because of poor Class D implementations, but I'm not opposed to switching supplies / stuck in greybeard mode. Feels like the power supply stages come from someone simulating in LTSpice and realizing in the real-world they need 100,00uF to get the performance needed because they forgot to add parasitic / non-idealties. Having designed some high-speed RF amplifiers I question a lot of the reviews that claim switching is the devil. I'd love to see someone do a modern high-fidelity, high-power Class D design using discrete eGaN parts. If I had more time I'd take a crack at a monolithic PCB gluing a Sabre or DSP+R2R DAC directly to the output stage and try to get some tests run on it.

Looking at the Emotiva XPA-3 series and learning some more about the Hypex modules that power the NADs (slash looking for the older non-Class D gear). The XPA-3s are still Class A/AB and that Class H supply looks very well designed. Not going to try to pick an amp that can do well for both music / HT usage; will cross that bridge some other time (perhaps the modular nature may pay off then...)

e: This is a weird question, but does anyone make "cosmetic" cables? I.E. things that look super fancy / audiophile grade, but just add a few bucks of shininess to them. Monoprice's XLRs already look pretty good but I was thinking some more shiny would help me in messing with some of my absurdly serious audiophile buddies. It's a weird request, but in a setup where everything is exposed...

Honestly if I was in your budget I would just look around for a used NAD S200. They’re...beefy and usually fetch around 7 or 8 hundred on the used market. Balanced inputs, 220wpc, class a/b, big honkin’ toroidal transformer. Basically all you would ever need for power for 2 channel audio. (Or say gently caress it and find an S300 and melt your speakers)

Speaking of used NADs (heh) found a M22 for $1600 which is a nice chunk of change off new (no warranty though). I'll take a look at the details of the S200 too. Looking at the M22 vs. the Emotiva XPA-DR2 which new is almost half the price of the M22. I guess the Emotiva somehow ends up cheaper with a Class AB+H hybrid vs. the NAD's modules.

Stereophile has review data on the XPA-2 and M22 with the former showing nasty intermodulation but I'd have to go listen to see what that equates too to my ears. No idea of the -DR2 would solve that intermodulation. The Emotivas generate a better squarewave (probably from not being Class-D) but hard to be data-driven on this when listening is somewhat subjective. Might just have to factor in a return-period / return shipping and try them both out somehow.

Is the difference between B&W CM8 and CM9 at noticeable IRL? I'm considering picking up a used pair as they're occasionally available for what seems to be a reasonable price (around $1k for both). I never had decent speakers beyond like $100 PC 5.1 setups though I do use Ety ER-4 when I'm serious about listening to music, so I think I'd be pretty happy either way.

I don't mind used as you can often get way more for the buck but both are fine. With speakers like that I'd probably start with just stereo although having the ability to go 5.1 later would be nice. Price range is ugh... like $500? It's somewhat flexible and I'm not sure what would be appropriate, but there seems to be a lot of choice at this level. Source is just the HTPC playing movies, games and lossless or lossy music.

I’ve heard good things about the Marantz NR1508, 4K pass through, 50wpc, Dolby vision compatible, Bluetooth and wifi. There’s one on sale on amazon right now for 399, sounds like everything you would need and it’s not too monstrous like most AV receivers.

I will only use the bluetooth headphones for TV and music listening. I can connect my BT headphones to my TV, but if I want to switch to using my computer, I have to disconnect my headphones from the TV and then connect them to the computer. This is a pain in the rear end.

Maybe someday I might try out 5.1 sound. At the very least I may get a subwoofer.

I'm leaning towards the Yamaha RX-V383BL, but I see it only has one optical in port on the back. My TV has an optical out port, as does my PS4. Since there is only one optical in, that means I either my TV or PS4 will have to be connected some other way. Will this be a problem? Also, the 383 doesn't have WiFi.

Optical isn’t as good as HDMI, with HDMI you can do uncompressed linear pcm, optical also can’t do Dolby TrueHD or the DTS equivalent so yeah, HDMI for audio is better than optical.

I'm going back and forth on whether to get an AVR and pair it with the two good/decent Bose bookshelf speakers (I was given them and my Googlin leads me to believe they're ok) I have now and adding speakers over time as the budget allows, or to get a Vizio 5.1 soundbar. I'm considering the Denon AVRS730H at $350 or whatever Vizio 5.1 soundbar system is around that price, but someone could talk me out of that.

I've got a 2015-ish Vizio 5.1system on one of our TVs and it's ok to us.

The real question is whether or not me or the other regular TV/movie/music listeners in my household are going to regret having to watch stuff with only 2 channels and no center channel.

Is it going to suck? I mean, I realize lots of TVs just have 2 channel speakers built in, but the separation is going to be even more so it makes me wonder how its going to work out.

So, what I ended up doing is using the Bose 301 Series III speakers with a 15 year-old Onkyo receiver and it works pretty great for TV/Movies and some music. I was thinking about adding the Polk PSW10 that's on sale at Amazon for $80 bucks today. Anything particularly bad about this plan?
