The Legacy Powerbloc4 is the perfect option for bi-amping speakers and high performance surround sound applications. Audiophiles will appreciate the detail and resolution from the ultra-wide 1.5 Hz to 70 kHz bandwidth. Professionals will love the abundance of effort­less power.

Incredible performance in a small package...at a fair price.

Characterized by a solid and taut low end with fully developed shimmer in the top extremes, Powerbloc2 is one of the most versatile refer­ence grade amplifiers ever. Now, the Powerbloc4 provides the same performance across four channels! The Powerbloc4 hosts a pair of 30 amp power supplies, each powering two channels.

The benefits of multi-amplification are inarguable: lower intermodulation, greater headroom and freedom from harmful clipping. Yet concerns over cost, bulk and complexity have prevented users from enjoying these sub­stantial advantages. The Powerbloc4 can be used to bi-amp passive speakers alongside Legacy Audio's DSP based processor/crossovers to raise system performance to a new level. They can also be used in high performance theater applications to power center and surround channels.

Numerous refinements to class D topologies in recent years have resulted in improvements that not only match the neutrality of other high end designs, but actually exceed typical performance parameters in several ways:

    • High damping factor
    • Low output impedance
    • Wide bandwidth
    • Huge dynamic range

    Stable into low impedances, the Powerbloc4 achieves high output without bridging and is exceptionally quiet. No transformer hum, fan noise or long waits after power cycling for stabilization. Extremely stable even when driven hard, the ultra-efficient Powerbloc amps feature short circuit protection, thermal sensing and 12VDC triggering. Inputs are premium hand soldered XLR balanced and gold-plated RCA inputs, as found only on the finest gear.

    The Legacy Powerbloc4 provides configuration flexibility with four channels of serious power... for serious listening.

    WOW, Fantastic, Suggest 150 WPC min for best sound.

    A very capable CD player at an excellent price. Also a better remote than many more expensive players. Highly recommended. Great service from Safe and Sound.

    Wanted to love it but didn’t. Lacks dynamics compared to similar priced Emotiva Differential amp. Lacks dynamics and bass imo. At low volume sounds good. I listen loud.

    the upper midrange is still not as clear as i was hoping for on dialogue.

    I can’t tell if this was new or not. It was that clean. Amazing dea

    Amazing speakers and arrived on time and in perfect condition!
    Thank you!

    Very nice replacements for my Definitive Technology BP2000TLs. The sound isabout the same in a slightly smaller enclosure. Safe and Sound was very helpful and easy to work with. They delivered on what the they said they would do.

    I'm using them as rears in a 7.4.4 surround sound system. They are more a great for what I'm using them for.

    Hi I like the smooth looking style andthe way it plays without hesitation of music. No complaints

    Staff was very knowledgable about the receiver. It arrived on time, perfectly packaged and in amazing shape. Very happy with the purchase.

    Great price on the Musical Fidelity M6X 250.7 Amplifier

    Nice unit, quick service. Thanks.

    Great amplifier, solid build and excellent packaging from safe and sound

    Good unit, great sound and excellent set-up help for details not covered in the instruction manual.

    These speakers were the perfect fit for my Atmos speakers in my 7.1.2 newly finished home theater. They not only have a high power handling rating, they have a very balanced, smooth sound. I have been so impressed with them that I purchased two more pairs to be used in other areas of our home. Highly recommended.

    Love the speaker and great customer service

    Excellent . Had a bit of an issue with the wireless connectivity but sorted that out with my service provider. Did open a case with Bluesound support which was good overall but they really did not attempt to troubleshoot. Just sent me some links . Back to the Node Icon a great streamer have used Quboz and Apple Music no issue and HI Res music is great on my vintage Marantz 2220 and Goldenear BRX speakers. I highly recommend the Node Icon. Also excellent experience with Safe and Sound quick delivery and will buy again from Safe and Sound.

    The sound is amazing and the shipping was fast. I got the speakers the second day. Very satisfied!

    Excellent streamer, pairs great with the Burmester 088 preamp. Love the EQ feature..

    I had to build a wall to put the JBL Arena 55IWs in. After doing so I am very impressed. They measure very well, with no notable issues at the crossover point of the woofers and tweeter; and with them being in walls, they address a lot of boundary related issues in the 80-300hz region, this makes subwoofer integration better as well.
    Thanks to Safe and Sound for the quick shipping and great price on these.
