I'll give this Penguin "CMOY" a 9 out of 10. Fantastic sound for such a small DIY. Sounded very good with the Koss and Sennheiser. If not for the rather sparse and loose fittings I'll defintely give it a 10! Bravo!

I'm in but might have to fake some IDs for the minors!

I bought my new at $180 from Hung brothers!

Should have posted earlier. Just bought mine yesterday afternoon!!!

I think someone should close this thread?

Just bring some extra i/cs

Tested it with the stock tubes with my HD580 + equinox, sounded quite decent and musical. But I was told it might help if you tube rolled - no experience rolling the T-2A. They are value for money if you ask me. Almost bought one for RMB1800 but had to giveup as my other audio purchases were over 50kg, phew!

I'm intersted in the Tivoli Model CD. Appreciate any feedbacks on their products.

Pleassee bring them along. I've listen to them for bout 20mins in China and will love to check them out again.

It all depends on what Mac peripherals and software we are using with it. I'm a Mac Classic collector and restorer myself, have used the Macs for professional audio editing and broadcasting. Have you heard of the "Protools" by Digidesign used on almost all CD/audio mastering? Well they basically run on a Mac. You can download a LE version Mac/PC for free from their site. But beware, you will need extra hardware and power to go realtime with more than 8 tracks. Can always find something on ebay - cards / softwares.

Forgive me asking, but how and where do u actually use the "plugs". I'm guessing they are like the 75ohms terminators used for terminating video signals in video systems?

The first batch had the all "silver" chasis + unshealthed transformer. The later units mostly come with the black top + shealthed trans. Northern Oak's "black" top unit was shipped directly from the factory. I was told that they do not produce many of them. I'll like to share my personal experience bout the hum/noise from my RKV. I've tried the Sony V6 & other low impedance phones plugged directly to the RKV, at zero volume, no source input, and I do get some hiss and noise. But with the impedancer everything is OK. Must be impedance matching haah? BTW the RKV impedancer is 8, 16, 32 & 64 ohms, quite different from the Cayin's rating.

I guessing that tomcat's Cayin's could be from the first production batch, i.e. the transformer without the metal shealthed cover which explain the hum. It could also be that his 12AX7 and 12AU7 are placed in the wrong sockets, I think? Correct me if I'm wrong but teh 12AX7 should be closest to the window. Damn Chinese tubes & manual got no indication and markings at all. I reckon it is not healthy for you turn your volume up to 1 o'clock, most of time 9-10 o'clock will suffice to enjoy any kind of music.

If your are talking Norah Jones CD, my opinion is that the local CD pressing & engineering sucks. You should listen to the SACD hybrid pressing - much better engineering and sound quality.

I've a couple of dozen of pepsi blue that I share with everyone but need some wheels to transport it over. Any volunteer?

OK, I'll bring along the impedancer for the low IM cans + my HD580 & equinox. Looking forward to testing the R10 on the RVK!

Bring your discs to the meet and try out the other sources.

I'll be coming definitely! Anyone interested in listening to my RKV? BTW what kind of source do we expect to see at the meet? If someone can provide transportation, I can wheel along my Cyrus CD7Q+PSX-R.

Can I come, can I come? Pardon me for asking, exactly where is the meet?

What is the age of your Grado, possible to post some pics?

The Cayin is awaiting payment next week. Both items might also turn up at the next meet. Moderator's edit: Both items are sold. Thread is locked.

SOLD to a lucky fellow member of the forum.

It is the 2.3 from now with SACD. Opera has stop making the 2.2.

This baby is build like a tank, comes with a all metal remote control unit: Specifications: Using Crystal CS4396 DAC resolution 24bit 192KHz multilevel sigma-delta with synchronous upsampling Clock Jitter Less than 14ps directly distributed to DAC 0dBFS signal output 2.3V RMS Output Terminals Gold plated RCA unbalanced and gold plated XLR balanced Frequency response Less than +/- 0.1 dB deviation 20Hz-20kHz Phase response Less than 2 degrees deviation 20Hz-20kHz Signal-to-noise ratio More than 105dB (XLR output) Crosstalk Less than -100dB Distortion (XLR) Less than 0.002% Distortion (RCA)Less than 0.003% Intermodulation Less than 0.002% (19kHz + 20kHz) Remote Control Philips RC-5 compatible IR system 36kHz modulation frequency Dimensions / Weight 8cm x 43cm x 29cm (HxWxD) / 13kg Internal specification is similar to the co. reference series. Made by Opera Audio http://www.operaudio.com Bought this baby along with my other purchases from PRC brand new days ago. I've also have a Cayin HA1-A Amp that I think I'll have to let go because buyer says he can only pay end August but need the cash to payback the WIFE! The CD1.1 is for S$850 and the Cayin for S$680 firm. Send my a mail if you are interested. Mod edit: Edited your Colour tag codes to make it come out. Didn't touch anything else

Headphonecrazy paging for Northern Oakie, if you are around, please send me a note for my email, thanks.
