Lector 7T and tube rolling


I'v got this nice CD player, but would like to have even smoother highs. It has originally CVC Chelmer valves (12AT7) and I wonder if old Mullards, RCA, Siemens or other NOS would change this?
Is it important to have NOS from the 60's or is tubes from the 80's almost as good?

Thanks!

Just some more info:

I've now tried with Siemens NOS as well as RFT NOS (former eastern Germany I quess).
The RFT tubes are best in my system, giving more precise bass as well as natural imaging. Detailed without beeing edgy.

Mullards are next on the list :-)

Hi Blaine,

My Lector was used for appx 100 hours when I got it; I did not notice any change or break in periode after that.
Tube rolling may be the way to solve the edgy upper midrange.

I was using the Meridian 508.24 as well and this player seems smoother and less edgy in the upper mids - until I started to recognize that the Meridian in fact rolles of, giving this more soft and laid back feeling. With the Lector you are seated in the 2. row, with the Meridian (or other more laid back players) you are in the 15. row......the choice is a matter of taste.

I did try the Mullard as well, giving a more soft and Meridian like sound, but missing some of the very best with the Lector; the transparency and crisping and "airy" musicality (difficult to explain, my native language is norwegian *s*) My best choice so far has been the RFT tubes.

Another experience I have is that the lector works best with a tube pre, towards the warm side.

Good luck!

In regards to my post to Ole, (which I thought was going to be an e-mail, I need to start following directions), After 100 hrs of fully powered up and about 50 hrs of playing cd's, the slight upper midrange edge is no longer there! I could not be happier with this player. Warm, musical and no digital glare at all. This player for the money, IMO, is a great value!

Here are my suggestions:
1. Isolate the CDP well, and it really means great differences in musical presentation. I put them atop a BDR Shelf with BDR cones, and that was much better than the Seismic Sink (older model) I have.
2. I tried many tubes. So far I like the Valvo 6201 (blue lable is a bit better than the white)and the cheap GE 5 star also gives a more lively sound. Siemens ECC81 or ECC801 gives a more linear sound with solid bass.
