Designed with Intention. Crafted with care.

With hi-fi appliances, especially high-end equipment, manufacturers attempt to minimize internal vibration. However, this effort cannot completely protect against vibrations introduced by speakers and other external factors. This is where a trustworthy rack is essential to playing back your media free from disruptions to performance or causing damage to the equipment.

Floor pads are included for protecting hard surfaces from becoming scratched by the spikes.

The four-pillar design of the HF series racks is geometrically positioned to give the unit maximum support with minimum contact with the surrounding environment. This both aids in minimising the amount of vibration picked up by the unit and gives it the impression of floating.

Every element of this rack has been designed with the primary goal of enabling your system to perform as well as it can. From the very shape of the rack down to the rubber O-rings covering the spikes, every element has been considered. This is the Hyperspike Vibration Free System, designed by Solidsteel.

Eye-Catching

With the HF series, Solidsteel has crafted a hi-fi rack that strikes the perfect balance between form and function. There are harmonies and geometrical relationships between components, which as well as serving a functional purpose, offer the unit a visual contrast and air of professionalism.

High-end speakers and amplifiers are designed to look as good as they perform. The same is true for home theatre furniture. This unit is visually striking, designed not to outshine the equipment it houses, but to praise them. The hardware is made of high-quality stainless steel, polished by a state of the art process, resulting in the eye-catching smooth and gleaming finish.

The shelves are a unique quadrangular shape that is not often seen in hi-fi racks. Noticeably rounded without corners, this forms a smooth, graceful profile that offers continuity to its aesthetic and practical features.

Made Modular

This Hyperspike series is the only range out of Solidsteel's catalogue that is capable of being stacked. As well as further reducing external energy transfer, this enables you to set up the system as you desire. EIther as a single 4-shelf rack or several single-shelf platforms for your equipment. This modular design comes at no sacrifice to the core function and strength of the unit.

Ventilation Matters

Most home theatre devices need ample ventilation to ensure they don't overheat. Enclosed cabinets can cause unexpected shutdown and could potentially reduce the lifespan of your AV appliances. An advantage of a hi-fi unit like this is that it allows your equipment to breathe properly.

Grows with you

The HF range is expandable with additional shelves as you need. Turn your four-shelf rack into a five-shelf, your five-shelf into a six, and so on as you require.

Please Note:
Due to availability in Italy, shipping times for additional shelves may vary. Please give us a call on 1800 69 2225 for more details and for lead time on these extensions.

    Sound unexpectantly blasted for no reason. It malfunctioned!
    I spent hours between installation and set up! I had to return it. I turned on NET (network) to play Sirius Xm and the volume was low but after a few minutes the sound turned all the way up to maximum completely on its own? This happened at least two more times. I contacted ONKYO and was told it is clearly defective and that their is no solution to correct the problem, and that I should return it immediately! I purchased the newer model and am pleased with its performance! It’s unfortunate because the first one that had the issue with the sound really played nice, but having sound change its volume so suddenly to its full capacity was not what I expected, nor felt comfortable enough to keep as I said I was told to return it, which I did! My advice here would be to purchase the newer model, which seems to be much more stable in its performance, and the quality is excellent.

    Absolutely Love This Receiver
    The Onkyo TX‑NR7100 has completely transformed my home theater. The sound quality is rich, detailed, and powerful, and the 9.2‑channel setup gives movies and music a level of immersion I didn’t realize I was missing. Dirac Live right out of the box is a huge win — the room correction made an immediate, noticeable improvement. Setup was smooth, the interface is clean, and everything from streaming to switching inputs feels fast and reliable. It also plays perfectly with the rest of my system, and the THX certification really shows in how cinematic everything sounds. I absolutely love this receiver. It’s one of those upgrades that makes you wonder why you didn’t do it sooner.

    Incredible 9.2 Surround receiver at an unbeatable price.
    I may return at a future date to give a more complete review, but others that are much more knowledgeable about audio equipment than I have already done so. For me, the Onkyo (Onkyo TX-NR7100 9.2-Channel 8K/4K Network A/V Receiver) replaced a much older (2001) TX DS787 5.1 100 W Surround receiver that listed new for around $1050. I probably didn't pay quite that much but certainly something near $900. It was great for its time, perhaps even advanced with THX, Dolby, and other listening modes. But it didn't have: HDMI inputs or outputs, any BlueTooth capability, no hard wired or WiFi connectivity or basically any operating or connection modes that most all modern receivers have. This turned into a big problem with modern LED/LCD/OLED TVs, Alexa and other now common devices. I bought my new Onkyo TX-NR7100 from Amazon for $625. Other retailers (e.g.Best Buy) advertise it for up to $1200, so Amazon's price is outstanding. Set up was far more complicated (for me) than any previous receiver that I ever owned, mostly because there were a very large number of back panel input and output jacks, to and from the TV, as well as speaker outputs for 9.2 surround. Suffice it to say that once everything was connected properly (I made a few mistakes along the way), I was completely thrilled. The On Screen Display, completely accessible either from the front panel or the remote was far superior to anything I had ever seen before. Literally every operating parameter is accessible to the user. And I used most of them. It is also completely WiFi ready so my 150 Gbit home Wifi network lets it connect wirelessly and stream music error free. BlueTooth is also another way to connect almost any device to it for audio and audio/video playback if you connect the digital connections to and from a modern TV. It also speaks and listens to Alexa, although I must confess that I haven't played around with that much yet. This is already much longer than I had intended, so let it suffice to say that the Onkyo TX-NR7100 is an absolutely incredible receiver for an incredible price. I'd give it 8 stars if I could.

    Sounds great.
    Just received my Onkyo TX-NR 7100, watched a few YouTube videos before it arrived, so set up was easy. Ran accuEQ, I am getting new front speakers so I’ll wait to run Dirac. After accuEQ, I still had to make a few adjustments, to the speaker levels and especially the sub. It set my subwoofer way too low. As of right now having no problems with Bluetooth. I’ve only listened to music so far, can’t wait to watch a movie. For now I have a 5.1.2. System, getting new fronts, the Klipsch r51-m’s will go to the rear surround and Klipsch r41-m’s will be my height speakers in a 5.1.4 system. So far loving this avr. Update 2: Just calibrated with Dirac for the 6th time. They tell you if you sit in a recliner, reclined measure with it reclined. Well I measured with the chair in its upright position. It makes a huge difference I hear the surrounds much better. Btw I listen to all channel stereo, I know audiophiles say it sucks, however I listened to 2 channel stereo for 20 years, when there was nothing else. I didn’t buy a 9 channel avr to listen to 2 channel stereo. Like Randy the cheap audio man says “ audiophiles aren’t always right. If it sounds good to you, that’s all that matters.” So try calibrating in the upright position, or if you sit on a stationary chair or couch, try positioning the mic slightly forward of your listening position. It makes a huge difference. Hope this helps, enjoy. Update: Ok bought Klipsch rp-600m speakers for the front with 52c center. 51m surrounds, 41m rear heights. Polk owm3 front heights. Why Polk? Lighter easy to hang and as height speakers they are only there for atmos. Ran Dirac live, the application does what it would take several hours to make it sound like it does, if I even could get it to sound so good. Apple TV 4K with my Hisense U8K. The google tv interface is ok, but Apple TV is faster and easier. The Onkyo 7100 is a gem, runs pretty warm but I have it out in the open. If you are going to put in a cabinet I suggest a fan. Very happy with the whole system.
