-snipped-
3. meron akong nabasa dati na cd-player i think marantz ang brand nya na me tube sa loob nito maganda ba ito at meron ba niyan dito at magkano kaya.
Hi Rony,
Ok pala pare e, meron ka na ng X-10D. Isang hakbang na yan patungong tubes. Actually, tube na nga yan.
Pero, mukhang naubusan na ako ng sasagutin dito ah. Sinagot na ng mga kapatid natin sa pananampaltayang tubes halos lahat ng tanung mo. Pare, nahihirapan na ako. I-inglesin ko na to para umiksi. Hehe
. Pasensya na pre’.
Sagutin ko na lang ang #3 question mo, yun lang ang medyo nawisikan lang ng sagot
. Well, for starters, the main parts in a typical cd player are usually the
cd transport mechanism, the digital-to-analog converter (DAC), power-supply, and the output stage. Moreover, most players use a very simple one-component solution for the output stage and it's called an
Operational Amplifier (op-amp). Huwag ka magalala, nahilo rin ako nung inumpisahan ko to.
Actually pare, there are a number of tubed/valved cd players in the market, one is the
MF Nu-Vista 3D choke-regulated cd player with the rare nuvistor tubes, another is the
Jolida JD100 tubed cd player, and the yet to be released and perhaps the most aesthetically striking, is the
Music Hall CD-T100 cd player. You really ought to see it so that you'll know what I mean, here’s the link:
http://www.responseaudio.com/CDTP.htm Then there are companies that modify these
Marantz cd players you mentioned. Two comes to mind and both are Dutch:
Ah! Njoe Tjoeb (pronounced as “aha new tube”) and
Heart (pronounced as…eh “heart”
). Why Marantz you say? Well, aside from it being mass produced (“cheap” in other words), one of the main reasons is because of its
Philips Servo drive. It's already a proven and time tested drive that is used on numerous "high end" players and transports.
Anyways,
Ah! originally came out with the
Tjoeb ’98 then the
Tjoeb ’99. And to date, owner
Herman van den Dungen has released his latest cd player: the
Njoeb Tjoeb 4000. This is essentially a
Marantz CD4000 cd player modified with a tubed DAC, hence the “4000” moniker. Ah! offers a variety of tweaks for their li’l player. Aside from changing the stock
6922 tubes to the more popular
Siemens 7308, they have these what they call
“Ah! Tjoeb Tjoens Op-amp Flavor Kits”, and comes in two... eh "flavors":
LC Audio AD825 op-amp or the
Burr Brown OPA627 op-amp. An absolute tweakers' delight.
Then there’s the
Heart brand manufactured by hi-fi dealer
Rik Stoet, who owns a small Dutch company that also manufactures tube amplifiers. Stoet though has a more extensive line-up compared to Ah!’s. These are the
CD4000, CD5000 and
CD6000. Yes, they carry the same model designations as w/ their stock Marantz counterpart (I must say, they ain’t very imaginative in naming their models
). But
Stoet goes a step further than Ah!’s valved DAC, this is by eliminating all op-amps from the signal path in favour of an all-tube output stage. If you check
Audio Asylum, most of the AA “inmates” pick the Heart's over the Tjoeb's, specially those who own both cd players. But of course this is, again, very subjective.
So pare, napahaba na naman ako. Pasensya na. May pagka-insomniac kasi ako e.
Sa susunod ulit,
