Been back in the hobby for a few years now. Did some upgrades and had the system and room sounding great until I decided to build a component rack. Room still sounds very good but the rack was a giant step back sound-wise. After fall chores are done I will get it resolved one way or the other.
Have you fixed your issue with your existing stand? Let me know if you retained the stand. I can help you couple it with a few really sound ideas. Right now it is a conduit for vibration of all components.
I do know for certain that soft wood pine with its open grain structure is a poor choice and will soft and defuse the sound a fair amount. My experience is oak really boosts the bass. Maple is also a hard wood like oak with a dense grain and is supposed to be a good choice, but it just didn't work for me, but many swear by it.
@mjcmt, thanks for the compliment and info on your experience. I used pine and was considering replacing the shelving with oak or maple, but it seems like those changes are not guaranteed to remedy my problems. Not sure how long I want to chase it for. There are a few easy changes I will try and if I don't see significant change I will I'll probably buy a rack.
Regarding the kitchen setup, we spend a ton of time there so it makes sense and the sound is pretty great for a modest setup.
Very fine audiophile equipment and listening room. It is excellent that you chose to add an amp w/ extra speakers for the kitchen with high-end equipment.
Is you diy rack maple. I had my tube integrated amp on a 2" thick maple amp stand with solid aluminum feet set on the floor, before I put it on the equipment rack of laminate veneered mdf. The difference was very noticeable. I always read maple is a premier choice for equipment, but I found it softened the sound by a large amount, removed detail, and eliminated dynamics and the leading edge of the sound. Maybe for some equipment it's a good choice but it was not my cup of tea.
Also if your steel uprights went straight to floor w/o being welded to a cross member at the bottom this should tighten up the sound. And if each shelf is set on isolation spikes that would help, as well as filling your hollow steel square stock w/ sand.
@milpai, thanks for the compliment. Yes was also pleased with the look but there are unquestionable issues with the coupling or materials. Once I get some help going to try direct coupling. If that doesn't work I may replace the shelves with maple, or just go in a different direction all together.
@frozentundra, thanks..the span between legs is ~63" but there are no issues with mass or rigidity. The frame is a beast. (see discussion in "tech talk" "DIY Rack *fail*). I believe the issue has to do with coupling or materials.Regarding my location, I am north of Boston. Growing chile peppers is a hobby and I like eating chilli too:)
I really liked your stand, until I read that they set you back. I thought dampening marerial help tame the vibrations. But looks like something else went wrong. Hope you can fix them and make the sound awesome again.
I am assuming that you are using Rhumba with Pass and Aerial? Can't help it, but I really like your stand, since it is not tall and accommodates the gear nicely.
@jond, thanks for the compliment. I'm going to deconstruct the rack and remove the damping material to see if that fixes the issue. If it doesn't, I will likely look to rearrange components in the room and purchase a solution from a manufacturer that understands this better than me. Never would have thought it but there is some weird science involved here. Thanks again for the kind words.
Nice looking system, I'm sorry the rack set your sound back but you did a great job on it. It looks solid and sturdy and expensive. I hope you get to the sound you want you certainly have the components for it. Happy listening!
@hendrixinc, thanks. The room was unusable before the treatments and I still need to spot treat a bit more. The realtraps seem very effective and have tamed many of the issues I had in the room.
@frozentundra, thanks. I went from a Parasound P5 so the basic Rhumba was a noticeable improvement. When I rolled in a set of NOS Amperex Bugle Boy tubes it took the pre to a whole different level. The sound was terrific prior to the DIY rack I built. Never in a million years did I think or believe a piece of furniture could have such an impact and in my case it is negative. The sound is still very good but the rack issue needs to be resolved as soon as I have the time to deal with it. Most nights I simply can not get enough and completely lose track of time; it is a great source of enjoyment.
