Modwright Oppo 105

I received my Modwright Oppo 105 today. It sounds good, but is relatively lean - and not very extended - in the bass. The sound overall is missing a fullness and organic quality that I associate with tubes as well. I have been using an Exemplar modified Denon 3910 for years, and so far I prefer it. Naturally, I am quite surprised and disappointed so far. I will be patient and put more hours on it, of course. I am very familiar with "break-in." Dan burned it in for 72 hours or more, but I have only put another 5 hours or so on it so far.

Has anyone else had this reaction/experience? Maybe it is the Electro-Harmonix tubes, and I need to try something else? I am also wondering about Dan's use of silver wiring. Thanks for any thoughts you have.

Jfz,
Dan`s response confirmed my suspicion that this was simply a faulty unit. I`ve heard this ModWright 105 for extended sessions and it is a marvelous sounding player.You`ll find out soon enough once your problem is corrected. You made an excellent choice.

Congrats - you have good ears. Many people would not pick up on the fact that something was out of phase. I expect you will be much happier once this is corrected, as it can be extremely annoying to listen to.

This a good example of solving the core problem.I`d always start with contacting the builder and going from there. Chasing different tubes,cables etc. would cost unnecesary money and increased frustration with no resolution to the problem.

Good news: After what I estimate to be about 110 hours of total burn-in (72 hours before shipment, 40 hours by me), I have "real" bass - more full and textured; better tonality, etc. I also have natural mid-range richness, much better dynamic range, and improved high frequency articulation and smoothness. I am much happier!!

Thank you everyone.

p.s. This is after both the extra burn-in AND switching the leads (connections) on one spsaker.(fixing the out-of-phase brought immediate improvement).
