[200 W] I bought the model 30 a few months ago. It looks even better in real life. I paired it with the new KLH Model 5 and it sounds amazing. So much detail and sparkle in the highs but never harsh, even on loud volumes. Im really happy with the purchase.

[45 dB (Typical)] I've owned my Marantz Model 30 integrated amplifier for about 2 years now and my opinion is absolutely definitely positive. I used this amplifier, ten hours a day, every day for months on end and it barely gets warm. I run B&W 805 Matrix speakers with a B&W PV-1 sub, connected with the high level connectors, to the amplifier's speaker terminals, as recommended by B&W.
This amplifier is, in my opinion, sensational. It's sound is detailed, rich, beautifully expressive, conveying every nuance of the music in a convincing and natural way. Any stops in the music are wonderfully black, it has tone controls, which can be switched in, if I want extra hefty when listening to some of my 70s rock where the bass is recorded a bit too quietly. I've also run B&W 802 Matrix S2, with this amp and it drives them with ease. Twice, stupidly, I have accidentally connected the speaker + and - incorrectly but the amp, just quietly shut itself down with no damage. I really love this amp and could not imagine anything better and would not, ever take the risk of trying to improve on it. I wish I could get people on the Hi-Fi forum I'm on, (What Hi-Fi) to consider a Marantz Model 30 instead of their usual choices because I don't think there's anything out there that approaches this amp at this price. It sounds like an amp that costs at least twice it's price. Absolutely Sensational.

[45 dB (Typical)] Hi there, I have to ask here since the Pre Amp chapter of the Model 30's Manual's is pretty simple. I'm connecting the input of my EAR HP4 Headphone Amplifier to Pre Amp Out output of Model 30 - no sound comes to EAR HP4 while in Pre Amp Input on the front panel with SACD on. Checked the cables: there is the sound, if connected SACD to Headphone amplifier directly, but not via Pre Amp output on Model 30. The EAR HP4 Manual clearly states, that the input should taken from the preamplifier. What am I doing wrong? Thank you!

[Silicon Carbide] IT WORKS

[Silicon Carbide] I bought the model 30 3 months ago along with the SACD30 and paired them with Klipsch Heresy IV speakers. I listen to a variety of music including classical, jazz, Blues , Bossa Nova and Rock. This system can put great detail into the sound and at high volume the Marantz shows no sign of distortion or stress.

[-10 dB] I replaced from pioneer d amp by this AHB2.
Both product is enough great for me.
But AHB2 must be quite accurate amplifier.
Uncolored clear sound/amplified , that's is my comment.

[200 W] Love it!!! The sound is amazing for sure. My first Marantz and I am hooked. Paired with Heresy IV.

[200 W] I don't normally write reviews because I'm usually too busy enjoying the products I buy. But this time things are different. I feel utterly compelled to tell the world about this gem... The Marantz Model 30 is a first-class integrated amplifier straight from the hand-crafting magicians in Japan. You can feel the heft of the engineering that went into this thing. From the heavy metal remote to the weighty chassis, the smooth moving knobs and the OLED porthole, this amplifier is spectacularly built... But lets not stop there. You buy it for the sound (mostly), right? - Well, let me tell you. The Marantz Model 30 sounds heavenly, I mean seriously heavenly. Rich, lush, smooth, balanced, controlled, deep, powerful and detailed. You can listen to this thing for hours and be completely entertained; never fatiguing. And the rich detailed powerful sound-stage is absolutely mind blowing... Just be sure to set up your stuff properly (speakers) and this amp will reward you by transporting you to another dimension. No really, it's that good! - My best audio purchase ever! :)

[200 W] The best stereo receiver I’ve ever owned! If you want the best, this is it!

[200 W] Ive been chasing the sound I want since the 80’s. I finally found it in the Model 30. It needs some serious breaking in and then it just blossoms! I will search no further, just a lot of enjoying the music.
