new player question: string changing

[ack]

Maybe someone with some experience can help me out...
I just changed the strings because I didn't like the pitch difference between the open E and the open A. I felt that the A string's pitch was too high, and since I bought this Dean used, I didn't know the brand/guage of the original strings. They had a nice rumbly sound to them, but the pitch difference bewtween the E & A was not to my liking. I thought that if I change to larger diameter strings all would be good (or at least, better). Wrong.
Now the guitar sounds mechanical and tinny. (I don't use a pick, and I miss that softness sound that I had). It's an inexpensive starter (Dean Edge 1 - I'm saving up for a G&L L-2000 Trib), but it sounded much better with the old strings. Anyway, when I had all the strings off, I cleaned it up and tightened all the screws; bridge, pickups, etc..I put on Hartke "Transient Attack" HSB 445 Nickel Wound .045, .065, .080, .105. Are these just terrible strings, or did I do something wrong (my 1st attempt at changing strings).
Sorry about being long-winded, but I didn't want to leave anything out.
If these strings just plain suck, then any suggestions would be more than welcomed...hell, that's why I wrote this novel.
Thanks, Ack

For the sound you seem to like, the Hartke strings are the exact opposite of that. Have you thought about trying flat wound strings? That might be the sound in your head.

thanks..i just had a set of D'Addario XL's put on and it sounds great again. I guess the Hartke's just weren't for me...I appreciate your reply. ack
