Doge 8 or YS A2 or Jungson J2?

I've had a Doge 8 for about a month now. I would agree with the posters above that it's pretty hard to beat for the price, based on features alone: It's a tube preamp with built-in MM/MC phono stage, balanced outputs, nice remote control; heavy, with very high build quality. If this were not a mysterious Chinese brand it would retail for 2X-3X the price. I agree that there is frustratingly little information available on the web, so I'll try to give a few general impressions here.
First of all: I would buy it from Pacific Valve as opposed to a direct Chinese source, mainly due to the QC that they do on each unit, and because they warrant the product in the event of difficulties. I also think that some Chinese gear can have different parts and specifications depending on the source – the PV gear will be consistently high quality.
I am currently using the Doge 8 with a Cary 120S (used mostly in UL mode), powering Magnepan MMGs (soon to be modded). I’m using the balanced outputs (although I couldn’t hear much difference between them and the RCAs). The preamp features two single-ended outputs; one Chinese website says that they have different gain levels, but I cannot hear any difference.
I am also using a Cary SLP98F1 with the 120S, which gives me an opportunity to compare the Doge with the 98. I won’t say that one is better than the other; they both have different sound signatures. The Doge is more transparent and less tubey-sounding; as one reviewer says, it sounds like a smooth solid-state preamp (whereas the SLP98 sounds like the tube preamp that it is). The Doge has a slightly stronger overall presentation in this system due to its clarity and lack of coloration across the spectrum, but the Cary has slightly richer bass and a more accentuated midrange. I vacillate in terms of which I prefer with the 120S/Maggies combo; they are different experiences. The Doge retails for less than a third the price of the Cary, however. At some point I’ll sell one or the other (I buy and sell gear a lot); I’m not sure yet which one it will be.
The phono section comes with two switches, one for MM/MC and the other LR/HR (low resistance, high resistance? Presumably). The manual is no help in determining what these settings correspond to in terms of gain, load settings, etc. In fact, the manual actually advises users to not worry about the measurements, use the settings that sound best – advise that might be great for some but not for a nervous-nellie audio hobbyist like me. I found the MM setting to be too low-gain with the cartridge I am using (an Ortofon 4mv moving-magnet cartridge). The JFET-driven MC setting is too high-gain, and I assume the load settings are “wrong” on MC for my moving-magnet cart, but there is no way of knowing, and it sounds great – extremely dynamic. The LR/HR switch sounds terrible on LR with all the carts I tried, so I use the other setting. Verdict on the phono stage: It works especially well with a high-output MC cart and/or if you don’t mind not knowing at exactly what settings you are operating; otherwise you might prefer using an outboard phono stage. The line stage sounds so wonderful that the phono stage can be considered a bonus.
Bottom line: I absolutely would recommend the Doge 8.

I received my Doge 8 about 2 mos ago. I needed something to drive my tube power amps which are 2 highly modified Cit II's and a highly modified st 70. These amps require a fair amount of input voltage to reach rated output. The Doge has a robust output and is a great match for these amps. I agree with all the reviews Ive read on this pre and in particular with Salvatore, http://www.high-endaudio.com/RC-Preamplifiers.html whos opinion I dont always agree with. I would add that the mc step up sucks but I am using an sut into the mm input and it really sounds good. I initially purchased this pre as a temporary fix while I decided on and acquired what was hopefully to be my last pre. I have been able to borrow a few nice units to try out since buying the doge and have yet to find something I prefer. A few improvements would be a tape loop, balance control and either get rid of the jfet step up or at least use good ones. This pre is easy to recommend because whatever your expectations are, at its price point it will surely not dissapoint and will be easy to sell. In my case I was (am) ready to spend $7-8k and have yet to find something up to that price point that significantly improves on the Doge. I must add that the first thing I did was replace the tubes and after trying a few different types I settled on tele ecc 801s for the phono and tele 12ax7 smooth plates for the line stage. Depending on your system this pre is a real value. ( I did have the added cost of tubes and sut)

After reading few good reviews of Doge8, and finding that for $1000 I can have full function preamp in one box I’ve made my decision.
I decided to give a shot and I bought 6months old Doge8 on audiogon. The preamp looks very different from my other components that are “standard black”. Different but very attractive all shiny with polished stainless steel front and ball shaped push buttons. As you mentioned this unit is rather heavy and built very strong what is in ++. Inside I have noticed 8 small tubes on PCB with a lot of long silver color shielded wires and 3 transformers. As you noticed there is 4 X 12AT7 tubes for line stage and 4 X 12AX7 tubes for phono stage. Supplied Chinese tubes were not musical so I’ve tried few different NOS tubes that all were good but a little different here and there. For line I have installed 2 Philips + 2 Siemens tubes that are strong as new and for Phono I have 4 Telefunken tubes.
How it sounds in my system? When I play CD’s or SACD’s on my Sony XA777ES player, sound of line stage I will describe as very pleasant – clean, transparent, musical, involving with very nice 2 D stereo imaging but not much of the depth. Lack of depth is something I need to work on in the near future. I do not have expensive speakers or amplifiers. I have old B&W CDM1 satellites and BAT Vk-60 amp, and perhaps it is too much to ask for excellent imaging and deep stage. I do not have first class turntable but rather standard Technicks 1200 MK (I disagree with pricing of “better” turntables and poor engineering of many of them) and a lot of records. The phono stage sounds also very good on MM with my Grado Platinium and ok but not as good on MC with Denon 103 cartridge. I think that Doge8 preamp is a well build very nice component. I would like to see better designed PCB to eliminate all long cable connections and perhaps tube power supply. MC stage need to be improved and perhaps step up transformers need to replace J-Fet electronics. All together I am a very happy with Doge8 and I will absolutely recommend it.
I will be glad to take any advice for speakers that can improve imaging and depth of presentation.

Follow up to my review above: I am now using the Doge 8 in a system that feeds a Wyred-4-Sound ST-1000 and Magnepan speakers. It's a great preamp.

Ill chime in again, its three months later and Ive used the Doge 8 with some other power amps and compared it to a few more pres. I also finished a complete restore/ upgrade of my Cit 1. I have a hard time telling the Cit from the Doge. If anything the Cit 1 is a tad warmer. Everyone whos come over to listen is impressed with the Doge and agrees its a steal at Pacific Valves price. I tried a few other cartridges and suts and they all sounded great through the phono. A definite giant killer.
