Denon PMA-600NE Stereo Integrated Amplifier | Bluetooth Connectivity | 70W x 2 Channels | Built-in DAC and Phono Pre-Amp | Analog Mode | Advanced Ultra High Current Power

I bought this amp and connected this to my Definitive Technology BP10 speakers and Klipsch reference series powered subwoofer! Man this amp unleashed the beast out of those bipolar speakers. It matches very well with my 2.1 setup. The sound is powerful, crisp and crystal clear. It has 2 x optical ins (I’ve connected my tv and Apple TV to it), always loved the optic connections. I haven’t used the coaxial ins. Streaming done via Apple TV also sounds great! To be honest I can’t increase the volume knob more than 45 degrees in my living room! Excellent value for money! There’s no need to buy the higher models like PMA 800 or 900, this is just perfect!

A qualidade do som é excelente: uma outra experiência para ouvir música.

At a glance: excellent value, great feature list (for my needs at least), attention to detail in the design, step up in sound quality from my previous setups (vintage), good headphone amplifier. In detail: Sound is subjective (tastes) and relative (what gear are you familiar with). My previous receivers were mid-fi vintage units. I bought the PMA-600 to replace a Marantz PM750DC (early 80s vintage) which I thought sounded great but had nagging crackles in the left/right balance that I couldn't stand anymore. I also have a late 70s Fisher CA-2310, and 70s Kenwood KA-8300. Both of those are tank-like units with heavy, huge transformers and again, old gear develops problems over time. I love vintage gear and I try to buy used everything, so this purchase is a rare one for me. Basically I was tired of amps that worked well "most" of the time. My speakers are custom-built bookshelves with Scan-Speak drivers and I have a custom 12" sealed-box sub, all DIY gear I researched and built myself. I also have several Grado Labs headphones, Audeze LCD-2C (my best set of cans), a bunch of audio interfaces and a Aune T1SE tube DAC. All this is context to give a background of where I'm coming from. I started looking at the Denon PMA series on the advice of a thread at Head-Fi, about integrated amps which feature a good headphone amp. I'll also mention that my audio preference is typically toward "dark" and "warm". I think my hearing is on the more sensitive end of the spectrum, so hyped treble is a turn-off for me, and peaky, harsh resonance in the mids or highs is a stand-out, painful deal-breaker for me. Compared to my outgoing Marantz, this Denon has a ton of "detail." The treble is a lot more airy, the soundstage has more depth. It feels like the room I'm in got larger. FWIW, the room I'm in is not really ideal for listening (it's wide but not deep). The treble is a lot more "present" than the Marantz was or my other two listening setups are, but it's not abrasive to me and I'm sensitive when it comes to that. This amp has breathed a new sense of spaciousness into my listening. I had felt that my Marantz did a good job driving these Scan-Speak bookshelves but man, they sound obviously, unequivocally better with the PMA-600 and their tone is much more clear. Like a veil has been lifted. Bells, pianos, rhodes, cymbols all sound way more "awake". That's the biggest surprise that I want to emphasize: I have a very nice set of bookshelves and this amp has taken them to a whole 'nother level of richness. I hear new things in familiar recordings. In the end, that's what you always hope a new piece of audio gear will do for you. As for my subwoofer, this is not a fair comparison: the Marantz had no sub output and the line-level was super hot for some reason, so I was running speaker-level connections off one channel. Now with the PMA-600 I'm using the subwoofer output and again it's a big leap up. The bass is way tighter, clearer, just patently better in all respects. Things about the amp I love: EQ section bypass ("Source Direct"), "Analog Mode" is a really cool feature which shows the designers were puttin some love into this this amp when they were laying it out--honestly that was a big selling point that the designers cared enough to go to this length. When you switch between input sources it's relay-switched so there's a click and a pause which I like. Things I wish it had: an old-school "Loudness" mode would be great. My Kenwood actually has "Loudness 1" and "Loudness 2" which is ideal since you can toggle between 2 different loudness setting dependent upon what you're listening to. The Kenwood also has toggle switches which let the EQ tone controls have different frequencies. Surprisingly 800Hz on that unit really has a huge effect on the timbre and I love to throw that knob around to liven up some duller recordings. Some more EQ customization and a Loudness control on the PMA would be nice although I'm not docking any points for that. They are trying to bring the price point down on this unit and all that adds complexity. I hooked up a SPIDF cable to give the onboard DAC inside the PMA-600 a try: it seems good overall, maybe a smidge clearer/cleaner (and also louder) than my M-audio Fast Track Pro. However when I hook up the Aune T1SE tube DAC, there's little question that the Aune sounds sweeter. That's also an apples-to-oranges comparison though, since the T1SE is adding its own sauce in the form of tube warmth. Using my Audeze LCD-2C I swapped back and forth between the Aune and the Denon with a consistent volume setting. Since the line out on the Aune does feed to the tube warmth into the Denon this is an apples-to-apples comparison of the headphone amp sections only, with consistent DAC between the two. Again the Aune sounds slightly richer and clearer although the difference is not night and day here. If you wanted to plug headphones directly into the Denon, it is going to do a good job as a headphone amp. Not sure how well it would drive something with high impedance since all my cans are under 100 ohms. The LCD-2C are 70 ohms. Although the stated power is 45W, I feel it delivers plenty of power to my speakers. I don't remember the efficiency but I believe it was not super hot, like 87 dB. This amp can get them plenty loud enough for my liking. Like 1/3 of the way up on the volume control is getting too loud for me, with plenty of clarity. I usually don't crank the volume super loud but I definitely don't listen quiet either. All in all, I feel really happy with this purchase. I would recommend this amp.

Excelente amplificador, muy bueno. Tiene mucha potencia, sonido muy definido y potente. Ya incluye dac para Bluetooth, y salida óptica, pero mejora mucho la calidad con un dac externo. Algo que me gusta mucho es que se puede usar con medios digitales y análogos. También puedes desactivar el dac para que se escuche las salidas análogas directas y sin filtros. La tornamesa en el canal phono se escucha increíble y muy natural. Me enamoré de esté amplificador es una chulada. Además de excelente calidad de sonido, el diseño es muy limpio, y sencillo. Lo cual me gusta mucho. Una excelente opción al nivel de otros amplificadores más caros. Lo recomiendo ampliamente.

This is an amazing integrated amp for the price, sound is legendary. It will bring your speakers to life and such an elegant design. I have owned many classic and expensive receivers over the years; this is the best value and best quality of any modern equipment. Amazon delivery driver slammed the product with such force it startled my family in the house - shameful.

Highly satisfactory sound with hi-fidelity
