Something I came across recently that have me concerned, not knowing what's causing it. I recently finished building a pair of speakers, and the first set of measurements I took I was using my preamp and power amp so I had to use the headphone jack on a windows 10 laptop. The FR graph has a...

Hello, I began with REW this week. Please can you help me to understand why REW does not give me the same curve than Antimode . I measured my sub with both (put the mic at the same place of course) Why Antimode curve is relativly horizontal but not REW's? Is the difference important or not...

Just an announcement right now however many have noted that toriodal style isolation transformers can make audible and visual differences in AV gear but are not widely known. I want to personally test this myself so I can on my own testing see if there are any perceived gains. My original goal...

It's amazing the differences a sub crawl can make. I recently built a sonosub, and it sounded 'off' where it was, I left it for awhile, assuming I was just nuts. Today I went 'nuts' and rearranged my entire home theater to find out the best place to stick the monster... Here's what I found...

Hi, all. Something i have been wondering for a vey long time. I use my Onkyo receiver for both HT and music listening. The main point of thought is the differences between DTS Neo 6 and PL II music and what would be the best choice for audio listening on a 5.1 channel system.

Much discussion occurs on forums like this about testing and how one should listen for differences between equipment. I have been doing some A/B testing of several types of differences and have some observations. First of all, I find it hard to find differences in almost all of the cases I...

I know the "differences in amps" has been kicked around here until it is on its last leg, but what about pre-amps? If amps that spec out the same all sound the same (for the record, I do not believe they do), shouldn't pre-amps that share the same numbers sound the same as well? Surely the...

We have other threads that get into "Can we hear a difference?" type questions, the biggest one about amps, located HERE. So this thread is not asking the question "Can we hear a difference?", but asks the following question: How can one learn to listen for and hear the differences between...

Hello all, I am a newbie to all this audio calibration stuff and have been trying to calibrate the sound card and eventually take measurements. I have a few questions. 1) I am trying to use my onboard (built into the motherboard) Realtek ALC889 with REW. However, when I plug in a 3.5 mm cable, I...

I currently have an RCA one thats 10 years old and delivers up to 200 watts. I was wondering if there is any difference on how it sounds between brands/features?

In my signature below are two subs I built and the other day I sold the 10" ported Aura sub and connected one of the 12" eD sealed subs in its place where I listen to music...to state that I miss the sound quality of the Aura is an understatement. I believe the motor design with its copper...

Hey guys, I want to rebuild my 1803s with 5 or more spiders... be it very loose or very tight spiders to idiot-proof them. When I replaced the AP30001D something amazing happened... the van started playing as it was supposed to. Most incredible amzing low end output. Air movement that no one...

Hello everyone. Ive been putting together a home theater for a couple months and got a tv, speakers, even got all my cables today ups (all for 500 new). Now i don't have a serious budget for a avr (about 500) but have narrowed down to 2 choices. The onk 609 or a b-stock 808, but the 808 means...

I have noticed some major differences when calibrating with YPAO in the morning vs. around lunchtime. All possible variables minimized, same mic placement (left in place), I'm the last to leave in the morning, nobody home during day, noise levels the same (super quiet), and so on. I'm religous...

Hi, After lurking for a while, i see you are all pretty knowledgeable from what i've read. I'm looking for a new AVR to replace my onkyo 507. Maybe not right at the moment, but soon in the future. I was wondering if you could give me some insight. I have demo'd a few AVRs, mainly the more...

what differences (advantages) are there between the wd 73837 and the 73738 models?

I used REW with the BFD to get a "reasonable" response in my front row centre seat. When I checked the back row, it was way different. I'm just looking for suggestions. Pictures of my response graph (front row green, back row blue) and some pics of my theater below. The theater is 23'6" L x...

I'm looking to get all the parts necessary to do some REWing and I have a question about RCA cables. On partsexpress there are 2 types of 3.5mm stereo to RCA cables. One is $14 and looks fancy, while the other is a $2 generic looking one. Any reason to get the more expensive one other than...

I'm in the process of setting up my system (Yamaha HTR-6080 receiver) and I have a question about cabling and connecting my subwoofer. My preference is to use Acoustic Research cables (decent price and good quality), however, the only subwoofer cables they make start at 15 feet. I only need a 6...

I'm going to get a Gizmo for my computer setup. If you order through the website, is it v1.1 or v1.0? It seems to say v1.0 but I would have thought it would be v1.1 :no clue: What's the difference anyways? What do you lose if you have v1.0 instead of v1.1, or rather what do you gain with the...
