UPDATE: THIS CONTRACTOR'S LICENSE IS NOW SUSPENDED DUE TO REFUSAL TO PAY A COURT ORDERED…read moreJUDGEMENT. My initial review stated that I was forced to file a lawsuit against Brian Staller / Circuit Genius (legally known as: Performance Telecomm) for breach of contract. The matter is now permanently settled by the court. After the vendor filed an appeal, the Los Angeles Superior Court ruled in my favor and found Circuit Genius / Performance Telecomm liable for breach of contract. Owner Brian Staller calls this a "frivolous lawsuit" in his response to my initial review, but the facts prove otherwise. In his response to my first post, Brian called the lawsuit "bananas-level false" and "frivolous." The fact that I won a judgment against this company not once, but twice--once at trial and again on appeal--means that two judges ruled in my favor, finding Circuit Genius / Performance Telecomm in breach of contract. The court's decision validated the vendor's refusal to honor two key contractual agreements: 1. The Refund Scam: The vendor refused to process an agreed-upon refund for a Yamaha receiver (which the contract stated had "No restock fee if not wanted"). Instead, he attempted to coerce me into a "settlement" that required me to sign a document agreeing to no online reviews, legal proceedings, chargeback attempts or warranty support for work done. 2. Deceptive Practices: After agreeing in writing to return to my home and install a network rack at "no extra charge," he later refused to do so unless I paid a new 2-hour service minimum. He then withheld equipment that I had already paid for and refused to refund the cost of that equipment. **This Contractor is now a Regulatory Liability** More than six months after the final judgment, Brian Staller / Circuit Genius / Performance Telecomm has refused to pay the court-ordered debt. His failure to comply with the judgment has resulted in severe disciplinary action: 1. License Suspension: The Contractors State License Board (CSLB), has suspended his license for failure to comply with an outstanding civil judgment. (See CSLB Record for Performance Telecomm; License 117708). 2. Business Lien: I have filed a lien against this business to attempt to enforce the judgement owed (See State of California Notice of Judgement Lien; File No: U250127585224). This business employs deceptive practices and does not honor contractual agreements. Brian is desperate to get 5-star reviews and refuses to accept anything less even if it means bullying and using intimidation tactics with his customers. A business that ignores its legal obligations, has a lien against it, and has its state license suspended should be a major red flag to anyone reading this. Do not put yourself through a lengthy legal ordeal with this vendor. Proceed with extreme caution.

Brian of Circuit Genius is a true perfectionist. He is honest and detail oriented. His word is…read morehis bond and we were fortunate enough to have crossed paths with him. We live in the South Bay in house that was built in 1921 with lath and plaster so getting good WiFi is not easy. Brian spent a few hours assessing our entire house, Sonos system and TV's. He provided a thorough, detailed proposal that addressed our needs. He did not try to nickel and dime us or oversell as others tried to do. Brian goes above and beyond (went to Home Depot to buy mat black paint to hide marks behind the media room TV). The 4 people who work for him are impeccable and care about the job being done beautifully. We are so appreciative of his work and follow through. Brian came back twice to troubleshoot a technical challenge from old equipment, at no charge because he insisted the entire system work perfectly. Read the many 5 star reviews of Circuit Genius over the past 7 years, which are spot on- so very happy that we did.

To make matters worse, I started experiencing some very strange issues with the speakers and couldn't figure out what was causing them. Installation King came out, thoroughly diagnosed the problem, explained what was going on, and resolved the issue. What I appreciated most was that they didn't try to upsell me. Instead, they took the time to walk me through the system and provided several options based on my needs and budget. They were professional, knowledgeable, punctual, and easy to work with from start to finish. Their pricing was very fair, and I felt confident I was getting honest advice throughout the process. If you need help with home audio, speakers, smart home systems, or troubleshooting existing wiring, I highly recommend Installation King. Great service and a great experience overall.

Another thoughtful aspect was that IK texted to let us know he was on his way, and then ETA. Extra thoughtful in this day and age was to send us a pic of Eugene as he was driving here. BTW if you get Eugene as your installer you will be pleased!! All in all, good service and good value!

Advisor seemed knowledgeable enough, but after paying in full (over $16,000) they couldn't get it to work properly for almost seven months (yes, not days, not weeks, but months). First was a faulty balanced cable, that they promised monthly was on its way but never arrived. When it did, the techs they sent in August had no clue how to balance/set the very system Magnolia had sold me (and charged $1,500 to install). By then the original advisor had left and the new one promised to put me in touch with Pro-Ject's techs. He didn't and I had to track them down myself. Really? And no offer of a discount, credit, even apology. I asked at one point three months in for a refund of the cable while they found another and they refused. In short, once they have your money they forget who you are. No customer service AT ALL. Ending on a nice note, now that I have figured it out on my own, it's sounds AMAZING. But I'll never go to - or recommend - Magnolia for a high-end product ever again.

Not just because it is archaic but more importantly, every little thing I need fix (tune) required me to call my dealer who charges an arm and a leg. One day, all my speakers died, so I called my dealer, and they wanted my first born. So I decided to venture out and I found Definition AV. 1st, their service call price is very reasonable. They diagnosed the problem (the Amp died) surgically, but what's great about them is that they asked a lot of questions to truly understand my use cases. They recommended me to switch half of my system to SONOs and leave my living room TV's 5.1 audio system alone since it was still working. My previous dealer would had never recommended that because SONOs is more DIY and they would not be able to charge as much service money. Before they left, they even tuned up my 5.1 system just because they found some misconfigurations on they way. It sounded WAY better. I got the quote, the price is very reasonable and they came out quickly and upgraded my system. Now, my system works way better and I can use my voice control (my main method of controlling everything else in the house) to activate any speakers or speaker groups. I'll be a returning customer!

He showed up that same night after finishing his other jobs, brought a crew, and got everything completed before the walls were closed. The quality of the work was excellent, the installation was clean and professional, and the pricing was very competitive. I highly recommend Tony to anyone looking for quality low-voltage wiring, networking, or home entertainment installation work.
