tube CD player for tube integrated amp?


recent lurker, first time poster here.

I'm looking for the best midrange for vocal, guitar, piano music. Tube or solid state redbook CD player would be a better match to my current system (below)

Under my consideration currently:
Ah! Noeb Tjoeb 4000
Doge 6 with NOS tube upgrades
Marantz SA 8001
Cambridge Audio 840C

I recently upgraded to Primaluna Prologue II tube integrated amp driving my old KEF 5 series II speakers. The improvement is so outstanding that my 22-year audiophile itch returns.

Thanks for your inputs.

I have been overwhelmed by the sound quality of the Doge 6 CDP given the modest price tag. While I don't have any experience with the other players you are considering, I would be surprised if anything in this price class can beat the Doge 6.
You did not mention a price point , but I really like how my PP2 works with my Granite 657 CDP . It is very extended and resolving which compliments the PP2 nicely . This unit has seperate SS and tube outputs . The tube side has its own volume control and you can roll the tubes if you want to tailor the sound more to your liking . I have not found the need to do so .

They go for @ $2.5k new and are impossible to find used .

If you have not already done so , try rolling some Mullards into the 12ax spot on the PP2 . Added warmth and base without loosing that sweet top end !

Good luck .
Hi Cincy bob: have you rolled NOS in your Doge 6? I am new to tube electronic, thus have no idea what NOS tube is and am wondering if Doge tubes need bias tuning.

www.high-endaudio.com had a shootout in Dec 2007 where Doge 6 (with NOS tubes) is highly comparable to players like Reimyo DAP777/transport combo, Electrocompaniet UP SE, AMR CD 77, Accuphase DP77, but being the best "value" ie lowest price.

Hi Saki70: thanks for suggesting Granite 657.
The 4 players in my original post vary in prices from US$700 to $1500 (new). I could go higher with compelling choices.

Prologue II is said to be auto-biasing, thus I will consider rolling 12ax7 tube after my set is fully mature/breakin.
