Been back in the hobby for a few years now. Taking small steps to try to upgrade incrementally. Room sounds very good with all the major stuff done for now. Still have some untreated areas in the room that I will get to soon....for now it is time to enjoy.
@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.
@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:)
@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.
@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.
