My friends and I are very impressed with the overall music presentation. The music now is more pleasing to listen to! Tried rock, pop, Jazz, Vocal, Disco…the player now becomes a very good all rounder now!! Thank you very much!! On Jess’s Cambridge Audio 640C V2 ---------------- Customer Mr Leong’s feedback: Thankyou for modifying my CD player! I alwasy thought my weak link in my audio system is using a Home Theatre system Pre and Power amp for listening to CD Audio. (In fact, for CD Audio Playback, the Pre amp is just a bypass, it should go directly to the Power amp.) Ha, now that you have modified the CD player... it is so obvious that the CD player was indeed the weakest link... Now, the CD Audio sound sooooo goooood! Your modification is just amazing! Never expect the jump in audio quality is so great! Leong. Mr Leong, on his upgraded Cambridge audio 740C ------------------ Customer Kelvin’s Feedback: I just hooked up the 840C; Very Good! Immediately it gives better sound-staging and decay to notes. It is nice and smooth! Thanks!! Kelvin on his Cambridge Audio 840C. ------------------ Customer’s TC’s feedback Dear James, My 740C is much smoother and relaxed with the Bursons opamps. Last time I was always listening to details. Now I listen to the music itself. I dare say it’s a MUST for all Cambridge Audio players. People keep complaining it’s (un-modded) bright, lean and digital. With the Burson opamps, no more such problems. TC, on his Burson Opamp Modded 740C ------------------------------- Hi James, Just heard the upgraded Cambridge Audio 640C V2 last night. Generally there is more depth and body to the music. More details and better separation. I am happy with the mod. Thanks a lot! Customer on his modded 640C V2. ------------------------------ James www.effectiveaudiomod.com email:sales@effectiveaudiomod.com tel : 9694 9704 Edited January 4, 2012 by Effective_audio Share this post Link to post Share on other sites
Effective_audio 0 Report post Posted January 4, 2012 More Great Reviews: Burson Clock on 650C. Reviews: ------------------------------ Hi James, The CD Player sounds different. The instruments sounded more lively and vocals are more natural. The overall soundstage is MUCH better. Thanks! Customer, on his Burson clock installed 650C ------------------------------ Hi James, I have listened to the modified 740C. It is more natural, less bright and more detailed than before. Thanks for the mods! Customer, on his 740C with Ultima Clock package, opamps / diodes / caps changes and circuit modifications. ----------------------------- James. Initial feedback is good. Listened to "September" on the Daughtry album and the first thing that I said was WOW! Listened to the same song 3 times last Monday before sending my cdp over for you to mod and I still remember how it sounded before and how it sounded after your mod. Details on both vocals and on the instruments specially the acoustic guitar really came out. Not so savvy on audio terms but I think WOW says it all.... Will certainly consider the additional mod next time. Noel, on his 740C upgraded with Ultima Clock + Dedicated Power supply. ------------------------------------------------ Dear james, I am SHOCKED! You have transformedmy 840C to the big League!! Super black background, much higher resolution and inner details! And with HUGE soundstage too! I am enjoying my music so much more now! Incredible mod, well worth it. Thanks!
