I have just returned to Adelaide and your transformers were waiting for me.

I understand they arrived on 7/8/2012.  They look beautiful and appear to be in good condition.  The packing was the best I have seen from Hong Kong, and I have bought quite a few transformers from HK.

Thanks very much for your help here. 

A happy Analog Metric customer.

I love this JP-200 tube pre-amp very much. This order is the second of JP-200 preamp, because I wanted the second one as back-up for my sound serstem.

It's not a question, only a comment: Just received the kit and I MUST say it is a top notch item. I almost fell off when I opened the box: The quality of this thing would be unbelievable at TWICE the price.



Customer: Mark King
From: United States

 I was happy to see that the resistors were good quality, and the tube sockets, step attenuators... most of the parts are great or excellent. Thanks for that. The only things I will change are the tubes and capacitors, but yours are good too. I bought some Russian PIO caps, and got lucky recently and bought several dozen 12ax7 tubes -- Telefunken premium, and Ken Rad Sylvania.



Customer: Nakigaia
From: United States

Desiring to get a decent sound for decent money (aka bang for the buck)I built two of the preamp units from I would say they embody the essence of the originals without being direct knockoffs. First I built their version of the Grounded Grid preamp. It had a nice quality sound but lacked a certain richness and low end for my taste. Perhaps nicer for orchestra and some vocals.

I sold the GG board on ebay and started again with the JP200 kit. I have no way to compare to the original, but I am VERY VERY happy with the sound. What impresses me is the richness of the sound and the dimension and detail across the soundstage. A definite upgrade IMO from the GG amp and another manufactured tube preamp from HK that I had been using. It's like my system stepped up to the audio quality I was wanting, and for a minimal investment. I didn't have need to try the Marantz 7 board so I can't comment about that one.

I can't imagine anyone could gripe about the audio results of the JP200, especially after spending less than $400 to give it a try. My two cents.

; ]5 F; t6 }5 ^* VI have Bought the AM000593 DAC, and have just finished installing the DAC, and I must say, my old 10000$ DAC is rubbish, compared to this one - damn its good!


Customer: Kevin
From: United States

Wo~I have just bought a wonderful DIY Grounded Grid Preamp from Analogmetric!! It is absolutely silent in background. The spacial feelings and level of human sound is definitely clear and it is really outstanding. When I first time see this item, the price was very cheap and I suspected its performance by its cheap price. However, I felt it is my best and most reasonable DIY preamp I bought before. Really worth to try, recommended to all. 


Customer: Steven Ho
From: Singapore
C22 sound very musical, detailed. Staging and separation are extremely good, no drag at brass. Thanks


Customer: Paul
From: Australia

I have just completed the Analogmetric tda1541A dac kit ( in nos mode ), and it sounds superb. My question is that the 11.2896 mhz crystal (shiny little metal box ! ) that came with the unit looks like a generic unit ( probably is ok tho ) and it has four pins on the underside that connect thru the pcb. Can I install something like the LC Audio clock 3..or do I need a direct replacement such as the Tent labs vcxo ??, which should slot straight in.


Customer: Lampizator
From: Italy

So what Analogmetric did was to make the most beautiful, most gorgeous PCB which has provision for the great TDA DAC and all parts, some really needed - some not.  Analogmetric offer this PCB in multitude of variants - from empty and naked to fully working. Choice is yours. The price goes from 15 USD for the PCB to 270 USD for the whole working product. Any price point in between is possible - so your purchase is lean meat - only what you need and nothing you don't need. Nice idea, isn't it ?


Customer: TEWM

AnalogMetric A great selection of amplifier, pre-amp, power amps, USB DAC, power supply kits and much more and is easily one of the best supply depots for the DIY audiophile. They also sell transistors, ICs, capacitors, resistors, diodes, heat sinks and chassis. 


Customer: Vanersborg
From: Sweden

You can always check Hong Kong AnalogMetric, has a lot and not too expensive and they deliver fast: I bought the PCB to the Grounded Grid amp, but you can always buy a complete kit:: I bought this PCB:, but you can see that there's a complete kit to buy.

On various forums I've heard that your TDA1541A TDA1541 DAC (CS8412 / CS8414, SAA7220) PCB is excellent and very glad I ordered. Since I live in "Serbia" and there is a problem over the payment and delivery, I do not know how to get to the PCB and desperate sam.If you have any suggestions on how to get and pay please answer!

I bought and built the 7c preamp a few months ago. Sounds amazing.
It loves Baldwin/Sylvania 12ax7s. Also swapped in some Mundorf caps for coupling to tweak the sound a bit. Was wondering if anyone has adapted the all tube voltage regulator to this kit. I really would like to get it 100% tubes. Thanks
