Selling my dads top of the line system

I also forget he has a Velodyne sub and castle rock speaker cable. Paid 1.3K for speaker cable is that normal? I understand wanting to keep the system to honor him but I guess what I did not say is I am keeping other pieces. I have 3 kids under 5 and I honoring him buy using this money from selling the system to pay for there college when they are older. I am still honored by everyone on here for there support and help. 

My dad passed about six months ago, and I'm not trying to steal your thunder, or get any sympathy, but Andrew is absolutely correct: make certain that you won't regret selling what was obviously very important to him and a great source of pride for him. I was tasked in selling my dad's coin collection along with his knives, stamps, and other collectibles. It was agony selling any piece, and I still regret selling ANY of it...but needless to say I also ended up keeping a lot of it. If it was important to him, it's important to me.

My dad was a musician, and I grew up in the studio. He died when I was 17. I took all his gear to a consignment shop, which closed down, and I never saw or heard anything of it again. I regret it deeply. I wish I could’ve kept it and shared with my son. 

I totally agree with your strategy to use the funds from your dad's system to pay for your kid's education. A system like your dad's doesn't fit the lifestyle of a family with 3 young children and you would likely have to pack it up and put it in storage. For the next 17 years or so you won't even have time to listen to it. If you kept it in the house you would either have to put it in locked room or constantly worry that little peanut butter and jelly covered fingers will reek havoc. I wonder how much one of those Revel woofers cost? A much better tribute to your father will be to play music in your home as they grow up and to model an appreciation and respect for a variety of recordings.

Regarding $1k+ speaker cables, I'm not sure it's "normal" but it's not unusual for a serious audiophile. This underscores my previous point. Fancy speaker cables probably don't have an emotional connection with you. When it comes to preserving your dad's memory for your children I'm guessing there are lots of things that will have more meaning than his stereo. An expensive audio system is only one small slice of who your dad was and it sounds like you will keep a few pieces as mementos.

You have your hands full for the next couple decades. You will be sending your dad's gear to good homes and you can use the money for an important purpose. Your dad raised a good son.
