Cider many thanks for the info. Joseph is really going all out
With improving an already fine preamp. I'm hopping he has it all
Together by next month as I will be ready for rolling the dice
With shipping my 2,1 in for a upgrade. I've been lucky so far using
The usps you never no when your luck will run out though.

Sherod I went the audition route and would say Joseph gave me more
Than enough time and I was won over by the fine sounding 2,1.
I sure would like to hear from more AH pre users who have gone
The upgrade route.

O yea Siemens early 60s CCAs are a step up along with Josephs Dimension power cord and ICs. Time on my system adds up
pretty fast as i daily play at least three or four lps and weekends its a music fest down here.
After all these years i still cant get enough of that good ole classic rock and roll. |
Sherod aint life grand when your stereo can deliver that natural sound.
What kind of wire did you use.

Thanks Cedar for your update, i have a Transparency PC now on my 2.1. Sounds like Joseph is doing what he can to make a good item even better by refining it. I like what i m hearing using his Dimension ics with my gear good sound and well built. |
Gummajo i am going with V3 upgrade before pulling the plug on upgrading my 2.1. Not to dis this thread with other Manufacturing talk but the price is right and the prior 2 upgrades SE and V 2 were good moves to a better sound i cant pass V 3 up.
I m so happy with my 2.1 i feel the same way dont want to mess up a good thing for now. |
Thanks Cedar so what was talked about months ago with 2.1s upgrade is now 2.2 and thats different than what was done with the power supply and other parts of 2.1 then is that right. I use Dimension power cords Cedar can you compare with Josephs new design. just checked the web site and theres nothing new there. will keep an eye on this thread. |
I was looking at the Cable Companies selection and they list a newer silver model. It costs more almost double Acoustic Sounds at 59.95 anyone compared the gold and silver models. |
Ordered from Acoustic Sounds and went with the gold type, also got 2 for my Nuforce amps. Going to change the IEC out to a Furutech FI 09 gold and have one of those coming. |
For me now with my upgraded amps and using 2.1 i am most definitely not suffering from lack of music in fact i am in total musical joy with my system. I know from posts above on the power supply upgrade and clarity caps which with shrods help i added to my 2.1 i could not be any happier with Audio Horizons and looking forward to hearing what 2.2 is and will bring. Sometime change is good and then it can be a step backward so i will be checking on the progress of 2.2. |
Looks to be a winner like 2.1 would love to hear from users when broken in. I can attest to 2.1rnb this preamp is a very important part of my system and delivers music like i expect quiet, full body and image, a super sound stage, and life like timber.
Sherod using Clarity caps was an important move up. I just lost my money source and cant make big buys for now but i will invest in the hifi tuning fuse. |
Sherod on my 2.1 the fuse on the duel tranie board is a agc 1 amp type. |
Sherod i m sure because the HiFi tuning fuse is much more than a fuse it needs some time to get right. I did some PC moving and swapping this morning and yes it does take time even for well broke in PCs to settle down and sound good.
Looking forward to what the Hifi tuning fuses and Furutech IEC deliver. |
YGLim you dont need to open the case to get to the Nuforce fuse. The IEC incorporates the male plug and fuse. Theres a small tab that a small flat screwdriver will fit to pop the housing up and out the fuse clips into the housing. I had to remove the amp from my system to figure out how to pop the housing out.
Will post my findings with HiFi Tuning fuses and the IEC. |
YG my mistake for using this tread for Nuforce discussion. I will send you a PM.
HiFi Tuning Fuses are in my 2.1rnb and i now understand why a designer like Joseph would include them in his new 2.2 pre amp. Right off the get go the difference for the better is with substance, increased resolution transparency and air. Other very noticeable improvements timber of voice and instrument has that live true sound along with a better sounding system with these little wonders.
Guys and Gals do your self a favor if you spend a lot of time in front of your speakers and get in on this very reasonable costing tweak. IMO |
I swapped out the IEC in my 2.1 rnb today and must say that its another step up for better sound and i can see why Joseph chose to use the Furutech gold plated IEC. One thing i did not figure on was the difference in size between the original and the Furutech FI 09. I was using my old file for about an hour and a half to make the hole bigger to fit. Its worth the effort for better sound.
Between the Hifi tuning fuses and the IEC i think the fuses bring more to the table for better sound. I did not get a lot of listening time in yet so i may be jumping the gun. All in all these two items are highly recommended for users of this fine preamp. |
I wish i would have had better luck with my CCAs. I had them tested and 3 of the 4 were not even close. One of the 4 is acceptable barely. I ve had those in since early 08 and play a lot of music daily. Talking to Heinz he was surprised that my tubes had gone down that low in that amount of time. For now i m using 6H23 cryoed and for new they aint bad. I have about 50hrs now and music is sounding real nice. After day by day of listening i guess our brain gets accustomed to what we are hearing. I knew at the end that something was going because i know my system can sound better that it was. So if you havent checked those tubes lately you may be in for a surprise. |
Sherod when i checked my CCAs triode 1 tested ok on all 4 tubes but triode 2 was low on all 4 tubes i dont know about circuitry but i m guessing Joseph is leaning on the 2nd triode side of the tube. I m guessing i had over 2000hrs on them and there slow decay does lead to your ears adjusting to sound thats not as good IMO. The CCAs i was using were of the 70s version and i was able to bite the bullet and pick up 2 here on the Gon from the early 60s etching and all. Yes they sound fantastic in slots 1&3 using 70s CCAs in 2&4. I wonder if Josephs upgrade will have any effect on the drain of the 2nd triode. |
Thats weird for sure Sherod. I m sure you checked both of those switches for continuity with a meter strange that the new switch was bad. I can understand yours going bad with all of the use it has. I would unplug the unit and use the ohms setting on a meter to see where the problem lies.
I was being conservative on those hours and this time with the nos ccas i m marking the time in a log. |
Glad your back in music again Sherod the cold solder joint strikes again. Was a common problem with Westinghouse Elevator controllers the old relay type every connection was soldered a real nightmare for troubleshooting.
Those early 60s CCAs sound great in our favorite line stage but for a lot lower price the cryoed 6h23s are a bargain. You get most of what the CCA delivers not quite the micro detail but most all else. Looking at them its hard to tell the difference in them and a Siemans E88CC tube. Our Russian friends seem to have coped that fine Siemans tube. |
Sherod do you are any others AH users float your tube PCB. i checked back in the thread and did not read all but thought there was a kit or mention of this. as time when by this tweak slipped out of my thoughts but seems logical. i believe your going to like the Amprex tubes. after a long time enjoying my ccas and then finding out there fate was shot
i' ve been on the tube rolling plan very interesting for sure. |
Sherod i feel your pain. My buddy has a tester and it proved i had the same feelings as you with the degeneration of sound in my system, 4 shot very expensive CCA tubes. The Siemans CCAs are getting so darn expensive that i'm going to try something different. I have a pair of Telefunken PCC 88 7DJ8s and a pair of VALVO Hamburg PCC88 7DJ8s on the way. Its really getting hard to find 60s CCAs anymore for a price thats anywhere near reasonable. The Russian rockets do please the ears but cant approach what CCAs deliver IMO. Have you are anyone else tried any other tubes that can be recommenced with AH preamps. My AH preamp is the first tubed piece of gear in over 40 years in the hobby and tube use and differences were the reason i resisted. It seems that one triode gets worked out hard in our favorite preamp does that seem about right or is it the design. |
Thanks Sherod for the link would like to hear from those who have tried Gold Lions out. On the CCAs maybe late 70s and 80s versions for 150 to 200 bucks. And in my case those issues of the tube are no way as good as early 70s and 60s versions the Rockets beat them. Please let me know if you have a source for 60s and early 70 for that price. |
I got ya will do. I picked up a pair of early 60s here at the Gon for a bit more than you mentioned a short time ago. When i bought my AH i upgraded to Siemans tubes i believe they were e88ccs 6dj8 steel pins. Like you discovered i put the best i have in slots 1 and 3 and use others in 2 and 4. Thanks for the info |
Markwatkiss thanks for the link i' ve been tempted to try the Amperex ECC88s with 2.1 i have 2 VALVO Hamburg PCC88 7DJ8 - Single Tubes MINT NOS 1959-60 Hamburg Production and 2 Telefunken PCC88 7DJ8 - MINT NOS 1960s Bundeswehr Falcon Logo Diamond Bottom - Germany to audition looking forward to hearing the differences. |
now that ive tried the above tubes and volvo/amperex e188cc along with my 64 ccas and others no doubt they all have there own character and sound. the ccas are more thin sounding compared to the e188s while the amperex have better bass and mids IMO. in the end i believe until you audition a verity of tubes in AHs preamps you may be missing sound that appeals to you better. like finger prints and ears we are all different and what sounds better to me may sound like crap to you. i'm sure most of you have taken the time to experiment on your own and already know its worth the trouble and expense for better sound. |
