I recently purchased a pair of JBL 2453H-SL cds today. Much thanks to Molon Labe for selling to me and installing them for me. I got home around 10pm tonight and I've been listening for over two and a half hours straight. I can say straight up that there is certainly a discernable difference between the stock cds and these drop in upgrade JBL 2453H-SL cds.
The stocks cds that come with the 4722n are very good in my opinion. However I do recall coming across a bit of harsh treble on a small number of songs over the last six months. No such issue with these cds.
The highs are noticeably more refined, smoother, and very soft on the ears. The stock cds are noticeably brighter with more piercing highs.
Treble is definitely more pronounced and defined with these new cds in my opinion. Not convinced I hear any major difference in the midrange. No big deal since the mids were very good with the stock cd.
Listening to Mariah Carey's "You should be mine" right now and the vocal clarity in her voice is astonishly clear with these new cds. Watched Tron Legacy for a half hour and right off the bat I felt the dialogue was noticeably sharper and clearer in my opinion.
Dialogue and vocals with music is definitely more immersive now. It seems like the singers are singing live within the room because the dialogue and vocals are so effortlessly clear and soft.
I've owned many speakers from Martin Logan, Klipsch, Bowers and Wilkins, Yorkville, etc and they are not touching what I am hearing right now.
I recently heard a pair of Klipsch Jubilees in Houston and the 4722n speakers with the upgraded 2453H-SL cds best them on highs while I would give the Jubes a very slight edge in the midrange dept.I definitely like the upgraded 4722n speakers better than the Jubilees overall which says alot because I was obsessed with purchasing a pair of Jubes at one time.
These speakers truly are something special and I feel very blessed to own a pair at such an affordable price. The performance they offer for the price is just mindblowing.
I'm as tickled as a pig in slop right now. Thanks again to Molon Labe for giving me a chance to own the new cds. I also want to say I was given a demo of Molon Labe's system and to say it was impressive is a massive understatement.
His Dolby Atmos setup is the real deal. Hearing the sound of rain panning from left to overhead to right and behind you was unreal.
His 4722n speakers put out a huge soundstage so his entire room was the sweet spot. Bass with his SI 24 subs was deep, thunderous, sharp, and articulate.
Definitely one of the most articulate systems from top to bottom that I've heard. His media room is well treated and just flat out cool looking. And his house is gorgeous. He is a very blessed man. No doubt about that.
I also want to say thank you for Notnyt for all of the research and data gathering you did when researching possible upgrades for this speaker. Your skillset and willingness to share your knowledge to help others is greatly appreciated.
