They look like a good idea but dropping $60 + $7 shipping for something to use once or twice?? I'm not convinced.

Any other similar products? I realize for the sound quality, a person can't just grab an MP3 off the net and expect the same results . . .

 

That is very expensive. There are much cheaper solutions out there. Try a CD player cleaner. Mine came with all of that extra diag stuff.

 

A few years ago I got a TDK test CD on ebay for something like $2 plus shipping.

In my opinion the most useful tracks are the frequency sweeps, which helps you find those annoying rattles and buzzes. I've even made some of my own "test tracks" with slower frequency sweeps in the woofer and sub-woofer ranges ranges, along with some continuous-tone tracks every 5 Hz between 20 and 100 Hz, which for me is even better than the sweeps on the TDK CD.

The TDK CD did have some interesting tracks on harmonic distortion and a comparison between compressed and non-compressed music. Very interesting.

 

Wow! That set looks very cool! A bit pricey though.
One of my all time favorite CD's is a test CD put out by Alpine in the '80's.

Does anyone have this set?

 

The Sheffield Labs CDs are recorded to very high standards and are great for demonstrating (but not exactly measuring) sound quality. A true studio reference audio disc can cost into the thousands of dollars.

But for bass (my favorite) nothing beats the original Bass Mekanik. 10-100hz test tones, and fifteen tracks of spleen bursting ba-a-a-sss!

 

I use to have that set. Works great for getting the perfect imaging. The hertz CD is the most fun!

 

I just had a buddy with a CD burner make me one... Cost: $0

Just make your own frequencies with CoolEdit and write it out... simple

I have a CD burner - - Is it really this easy? I'm not familiar with "CoolEdit"

Additionally, If anyone still has these aforementioned test cd's i'd be more than willing to pay someone with a burner some moolah to burn me a copy + shipping + extra for the PITA factor of going to the post box - OR if someone wants to rip as pure wave files and ftp . .that'll work too. PM me if anyone is interested. I can PayPal the $$.

Thanks in advance.

 

How did you get all the hertz? I will send out a blank CD if someone wants to make me a copy. I have misplaced my copy.

 

Same here! I'd like a set!
