Andrew,

If anything, I feel that the AP-120 may not have enough gain

Driving the HD-600s through the headphone output, I feel it could go a bit louder. Through the normal outputs, I am having no problems. It all depends on what level the signal coming in is, how much gain the amp has and how efficient the speakers are.

I could change the values of the resistors in the gain circuit, if it is a problem. It would certainly be better than adding another mechanical connection and additional circuitry

Wayne, I was referring to the line outs, not the headphone out.   Audcoms are notorious for having too many volts on output, which is why the company went with the new Gain step-down switch on the back, and why the old 110s were best with a modded gain pot as well.

Hello All;

I am thinking it is about time to start a group demo.   I am wondering if there is any interest out there in a round robin demo of the JA-88C integrated amplifier?   The JA-88D is so big and heavy, that it will be too costly for people to send it on to the next person.   But the 88C is about right.  
If you have interest in hearing one, for a modest refundable security deposit, let me know.   Like the last one of these that I saw, a week or so for each recipient seems about right.  
Also, if you have any suggestions how to make this work smoothly, I'd like to hear it.

from what it looks like, it seems that any extra shipping costs are worth it to audition the ja-88d... i say send this one out for audition.

I recently received the Audcom AP-120

Well let me start this review off with the company. Sekei is a wonderful company to do business with. Andy has provided me with lots information on my purchase and a delight to deal with. The package came in just 2 days. The package was double boxed and in perfect shape. Shipping only cost $10.

   Now to the preamp, the Audcom is built a lot better than I expected for a piece that only costs. $329. Yes, I know only $329! The front face is pretty thick aluminum and the unit is pretty heavy for a preamp. I started off with the stock tubes, which were Chinese 12ax7. They were ok, and a definite improvement over using my Outlaw 950 pre/pro as the preamp. I already ordered some 12au7’s to do some tube rolling and experimenting with the sound. I went with the 12au7 due to the fact that this preamp has a really high gain output. It will put out upwards of 20 volts. Even though the 12au7’s lowered the output some, I still had to utilize the –6 db setting on the preamp. The only tubes I’ve tried so far are the Jan Philips. After about 4 hours of burn in I’m a happy camper. The preamp added the warmth and smoothness my system was missing. I don’t have all the catchy words or phrases to describe everything about this unit but what I will say it that it is very musical. I’m using this with a Krell KAV-250a and modded Magnepan MMG’s. The source unit is a DPA Renaissance cdp and a Pioneer 563a universal player. Prior to the preamp, my system had a harsh and bright edge to it. Now with the preamp in all of that is gone with all the detail and sound staging there. I do not have an extensive experience with tube preamps but from my various auditions in the local hifi shops this unit is on par with the Rogue 99 and the Audio Research SP-16. I’m not saying that the Audcom is better than them; I’m saying that I have no desire to go out and purchase them even if they were discounted by 50%. I like the Audcom that much. This is definitely the missing link in my system. The only downside is the remote. It is a pretty flimsy piece of plastic but other than that the rest of the unit is pretty solid. I’ve only got about 24 hours on this thing right now. I can’t wait to seed what the following months will bring and how the different tubes will sound.

Pioneer DV-563a
Audcom AP-120
Krell KAV-250A
Modded Magnepan MMG’s

Hello All:

Just wanted to say that I have officially sold out of stock of the AP 120's, AV 1000s, JA-50's, JA-2's, and after this weekend Middle Silvers.   Thanks to all here who have made this possible.

We are building our next order now, and sources are a big part of it, as well as some real quanitities of tube gear like the Audcom preamp and Meixing stuff.   If anyone has something they'd really like to hear, now is the time to tell us so we can be sure to order it.

Hello All:

Just for your general fun reading, here are some updated numbers on the Power supply capacitance for Jungson Solid State amplifiers.  The numbers are better than I first knew.   I recently asked for clarification, and here are the updates.

28 X 10,000uF = 280,000uF capacitance per Monoblock

JA-200 Amplifier Class A 200wpc SS Monos.
56 X 12,000uF   Total = 672,000uF capacitance each.

AV1000A Class A Home Theater Amp.

Hello All:

As some of you know now, who have bought Jungson gear, it is very high-end, just superb gear for the money.

Well, Jungson is considering price restrictions that will mean an increase in sales price, which could be a LOT higher.  

I have some gear left here, from my first shipment, but by the time I order again, the price will likely be way up.

Anyone wishing to get some of the stuff I have left at just above landed cost, should call me or email me quickly.   Once the price restrictions are in effect, I won't be able to make the same deals I have done so far.

Regards to All

Andrew

What about a list of what you have available.  I certainly don't need anything, but some of their stuff looks interesting.

[pugs]

Where are all the prices?  I hope they're on the website somewhere.

Audcom 120 review update

Well it’s been over a month now and I promised an update. I still stick by my guns on how good the preamp is regardless of the price. I did do a few tweaks to it, nothing major. I upgraded the tubes to Mullard 12au7, dampened the chassis with dynamat, added some HALO tube dampeners, and changed out the footing to Isonodes. All of these made subtle difference, but the whole was very good, especially for my setup. It gave the setup more focus and the soundstage expanded. The tubes really gave the whole setup the magical midrange that I was looking for. The high gain issue was also resolved by the Mullards. Everything was just more enjoyable. I was going to consider modding out the internals but I ended up changing out my amp to the Innersound ESL 300 and now everything has really come together.

In the end I would have to say this preamp is a no brainer. If anyone is looking for a truly musical preamp that just allows you to enjoy the music, than this is it. I don’t find that the preamp colors the sound like I once was searching for. Once I changed out my amp I found out how neutral and transparent this thing really is. If it is doing much to the sound it is doing it in a very good way. Comparing this to my Outlaw 950 in bypass mode is definitely night and day. Of course I expected that.

Hey:

The prices on the Jungson gear have been removed at the factory's request, because they were undercutting all the other dealers worldwide.  

Let me know if you want to know the price of any particular piece, and I will give you a quote.

Andrew
