    Benchmark DAC3 HGC (w/ ESS Sabre 9028PRO)

    The HDV820 is not a DAC. It is an amp. Although it has an internal DAC. I wouldn't buy the HDV820 for use as a dedicated DAC. And I wouldn't buy the DAC3 for use as an amp... The DAC3-HGC has a built-in amp, but I've never used it. You could get the DAC3-B, which is cheaper than the HGC, and...

    Benchmark HPA4 Headphone / Line Amplifier Impressions

    I'm running DAC3-B and HPA4. No hum with either.

    There's no hum with mine.

    Benchmark HPA4 Headphone / Line Amplifier Impressions

    An additional $2,000 for a "slightly" warmer sound? No thanks. You can get the same thing with a longer cable, a cable with higher capacitance, or a simple and free EQ tweak.

    Scratchy pot usually means there's DC on it. No bueno.

    Benchmark HPA4 Headphone / Line Amplifier Impressions

    Maybe. Power supply effects usually come down to filtering and the amp having enough clean power without any ripple current to meet any output demands. I think in these types of amps they can both handle your average 120v mains just fine, even with dirty power. I do have some professional Furman...

    Benchmark HPA4 Headphone / Line Amplifier Impressions

    Well Benchmark has a 30-day return policy. I'm certainly not going to wait until after that period is over to make a decision. Also, Benchmark themselves say there is no "burn in". They designed the thing so I'll have to trust what they say.

    Massdrop x THX AAA™ 789 Linear Amplifier - Impressions Thread

    Have put about 18 hours on HPA4 and THX 789. DAC is Benchmark DAC3-B. Headphones are Empyrean and HD820. They are quite close in sound. THX 789 seems to be a tiny bit brighter. Like the attack on bass and drum notes has a bit more of a snap to it. Whereas the HPA4 is overall slightly...

    Benchmark DAC3 HGC (w/ ESS Sabre 9028PRO)

    Been using DAC3-B (not HGC) with HPA4 and THX 789 and my Sennheiser HDV820. To my surprise (and delight), the DAC3 does sound better than the built-in DAC in the HDV820. It does bring out previously hidden details in my music. Subtle reverbs, echos, FX, background noises, etc. And music depth...

    Benchmark HPA4 Headphone / Line Amplifier Impressions

    Have put about 18 hours of listening time on the HPA4 and DAC3-B. Also compared to THX 789, HDV820, and Aune S7 Pro. Aune has been returned. HDV820 has been my DAC/Amp for a while. Both 789 and HPA4 are punchier and more authoritative than the Sennheiser. The HPA4 and 789 are quite close to one...

    Sennheiser HD820

    Weird. Maybe it's your specific market. Here in the USA, it comes with three cables: 1/4", 4.4mm, and XLR. But looking on the USA website, it doesn't mention the XLR cable anymore. I wonder if they stopped including it. I just bought my HD820 within the last two months and it came with all three...

    Sennheiser HD820

    Why are you waiting for an adapter? The HD820 comes with both a 4.4mm cable and an XLR cable.

    Benchmark HPA4 Headphone / Line Amplifier Impressions

    I'll be making the same comparison next week. I'm also interested in the new THX 877 from Monoprice and the SMSL SP200 which also has THX and 6 watts of juice. Wish I could have them all here at the same time but timing won't work out.

    Sennheiser HD820

    Yeah, I think the bad clamping force comes down to the loose connections between headband and yoke. Everything is just floppy. If the headband and yoke were tighter and more solid, you'd get better clamp force.

    Thunderbolt 3 Ports?

    Dropped my MacBook Pro tonight. It's FUBAR. Time to get a new one anyway. Been using regular old USB Type-A to Type-B on my dac/amp. But new MacBook Pro has Thunderbolt 3 (USB-C) "with support for USB 3.1 Gen 2." Not sure what that means. But what's the best way to connect this to my audio...

    Benchmark HPA4 Headphone / Line Amplifier Impressions

    See... two completely opposite opinions on the same two amps. Only way to know for sure is to compare them myself. I hope they're indistinguishable so I can save $2,600.

    Meze EMPYREAN - the First Isodynamic Hybrid Array Headphone

    Unfortunately, I found the Z1R to be downright disgusting. The worst headphones I've ever heard. The build quality is nice. They look cool. they seem to have cool technology. But they sound awful to me. No amount of EQ could save them, so back they went. The Z7M2 sound better to me. I haven't...

    Mytek Brooklyn Thread

    Has anybody compared the DAC+ with the Matrix Element X? Not talking about as dedicated DACs ran out to a separate amp, but as all-in-one units using their own internal amps.

    Sennheiser HD820

    I have Q5S. Sounds fine. Only thing I can compare it to is HDV820 and Sony TA-ZH1ES. Slightly darker, slower than HDV820. Slightly punchier, faster than TA-ZH1ES. Powers the HD820 just fine. No comment on imaging and soundstage. I also tried the FiiO Q1 MII and the K3. The Q5S sounded better to...

    New Questyle CMA400i

    I'm talking about impedance. Not resistance. Two different things.

    New Questyle CMA400i

    The Aune S6 Pro's output impedance is 22ohms and the S7 Pro is almost zero. That is straight from Aune.
