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.

Hi B,

I have the MW5400ES and found the biggest improvements in the areas of sound quality you mention to be, in order:

1) Philips 5R4GYS rectifier tube in the MW power supply. 
2) Shu Guang Treasure CV181-Z tubes in the player.

I would think these will perform similarly in the MW 105. The Philips 5R4GYS rectifier tube was a game changer.

I tried the Sophia and Sylvania 6N7's prior to the CV-181Z. The Sophias are very good tubes, bettering the Sylvanias, but more forward sounding with less soundstage dimensionality than the CV-181Z  to my ears.

Adding Symposium Rollerblock 2+'s  under the player on top of a Symposium Svelte Plus platform yielded significant improvement in sound quality as well.
