My space is 18 X 31 and
acoustically treated with RPG panels, tube traps and fiberglass acoustic treatment
over triple reinforced walls and ceiling. The floor is lamination beams
over steel plates to pier and beams. Two sheets of 5/8 epoxy
lamination sheets make up the floor with two inches of
concrete topped with India multi color slate.
rail system and fine textured acoustic cloth covers the work, making everything appear as a normal room with
painted sheet rock or decorative cloth covering.
The room acoustics were conceived by RBDG
and the entire space was torn out to bare dirt under the foundation and
bare studs in the walls about eleven years ago.
I'm in DFW area should you live near or travel through. You are welcome to listen with us. Tuesday evening is ideal as there are a room full of other music lovers and each has a system unique to their taste.
I have been following your system for years. One day I would like to be able to hear it, I will bring my friend with me. My friend and I have similar level systems... approx 60-100K for a 2ch system... nothing like yours, but we have some experience so we're not just tire-kicking enthursiasts but bonafide audiophiles. Would love to hear what those Grandes are capable of.
I hope all is well. Think of you and your system every time I plug my system into the Porter Ports I purchased from you back in '06. You were even gracious enough to take a phone call from a newer "audiophile". Thanks for taking the time to "talk shop" and the advice you gave me.
As usual your room and system looks fantastic. It's not just the gear but that the room looks so inviting and comfortable. Very well done.
I hope you don't mind a question( or two)? I noticed you have the Bel Canto e.One Ref 600m listed in your system page. In what capacity are you using them? How do you like them? I'm especially curious about the sound in the mids and highs.
I'm looking to put at least one hundred watts in my system with a budget of $3k and I'm looking at Bel Canto and Wyred 4 Sound on the class d front or an integrated from the Marantz Reference line. The system is on 14-16hrs a day so tubes cannot be considered.
I'm looking for big tone and a big sound. Ultimate detail and transparency is not a goal.
Having said that I'm just curious about your thoughts on the Bel Canto amps and class d amplification.
The Kuzma 4 point 14" may turn out to be my all time favorite. Great dynamics, almost zero tracking error due to length and tonal balance equal to SME V12 which is pretty perfect (in my opinion).
The Kuzma is one of the most expensive but other arms I've owned required after market tonearm cables. Considering the cost savings using factory (unbroken run) of cable from cartridge clips to phono stage and the Kuzma is in line for great value as well as top tier performance.
I loaded several custom parameters in the data base. I needed several for Allnic including 6AK6, E282F 8233 and 3A5. I don't remember how many of those existed and how many were custom but Amplitrex built me three or four adapters that allow testing in existing sockets.
I love the tester, biggest thing beyond what we point out is, it tests power tubes and gives accurate results. I've had three other testers and many will give passing grade on KT88, KT120 and KT150 tubes when they are shorted or have otherwise failed.
I'm a Mac computer guy but Win 10 is trying to make things easier. I'm still learning and plan to eventually buy a Brother label printer so I can attach sticker to each tube box with test results and curve trace.
The Amplitrex AT 1000 is a great tube tester. I've had mine for 5 years or so. The curve tracing is pretty cool. It's a great heuristic device too as it helps you learn about the tube parameters in your components, but it takes some patience. You should know there is a separate tube data file that you can customize by loading data in for new tubes not already in the database (although it has all the common ones).
Glad to hear the machine works with Windows 10. I'm using an older OS and may want to upgrade it at some point!
After running signal through the Kuzma tonearm for 160 hours I got it set up on my custom MK3 Technics. I choose the Air Tight Opus rather than Koetsu Coralstone since I tend to play the Air Tight more often.
Initial sound is very good, will take several weeks to get everything sorted out and adjusted for best performance.
I just received the new Kuzma 4 Point 14" tonearm and I'm working to get a custom mount board made for my Technics MK3 in Panzerholz +Rosewood plinth.
The Kuzma has a special order, 1.7 meter silver tonearm wire that runs unbroken from cartridge clips to RCA connectors into the phono.
I still have two SME V12 tonearms and will eventually have an opinion about performance between these two. The Kuzma will get the Air Tight Opus and the Koetsu Coralstone will remain in one of the SME V12 arms.
I started breaking in the Kuzma tonearm wire yesterday, running analog output from my DAC into it, and feeding the preamp. I plan on at least 100 hours burn before disconnecting from DAC and installing the MC cartridge.
Is there more to your test method or full disclosure as posted? I'm new to this tester but impressed so far. I had a KT150 power tube that was behaving in an odd way and the Hickok showed it was fine.
I tested via the Amplitrex and it showed short + partial gas problem. Not much gets by this tester.
I bought a cheap refurbished HP Windows 10 laptop and installed the software provided by Amplitrex. Now I can type in the tube number and it loads. No more scrolling through the electronic roll chart.
The HP is not yet set up to print data but it's capable via WiFi. The Amplitrex folks suggest a Brother brand label maker for addresses. That way you can print then peel and stick data to a "white" tube box.
That reads to be a great option, especially since there is an option for curve trace matching. Once I'm caught up I want to test all the tubes I have hanging around here. I have several hundred popular types, would be nice to know which are great and dispose of any that don't cut it.
Albert, I have the Amplitrex as well (about 3 years now). It's a great tester, but you have to interpret the figures. It's not just a simple reading like the other testers. I made a chart that may help you. I use the Fixed Bias setting. I use these figures Gm 90 to 100% Better than new, 80% Excellent, 70% Good (Average), 60% OK, and 50% Poor I believe the Gm which is like transconductance is what most testers give you. The Amplitrex also does Current. Enjoy Albert watch out though because friends will be bringing tubes to you or you will be making house calls. The tube doctor has arrived.
I received the Amplitrex AT1000 I ordered from Chris Terraneau a few weeks ago. I must say I am more than impressed by this state of the art tube tester as well as the customer service I received from Mr. Terraneau.
I needed to test common tubes found in high end audio but also the specialty tubes Allnic choose for their designs.
Some of the specialty tubes Allnic uses are:
Kron RS-242 in H5000 DHT phono. HL2 in H5000 DHT phono. 3A5 in D5000 DAC 8233 / E55L Magnoval base (second stage driver) in new Allnic M5000 amps.
Mr. Terraneau not only supplied Zip file with proper test data, but also built three tube adapters that allow Amplitrex testing with and without (optional) Windows laptop interface !
I found some tube errors in my system that did not show with other testers. Made a few changes and got a significant performance boost.
Of course the new Purist 30th Anniversary AC cables are the other side of this upgrade. My digital is literally better now than my analog was a few years ago (before the SP10 MK3).
I have 30th Anniversary AC on Allnic M5000 amps, Focal EM power supplies, Allnic L3000 preamp Allnic D5000 DAC and Allnic H5000 phono.
I moved my Purist 25th Praesto AC cables over to the two linear power supplies that feed Macintosh Mini and Data Tale 4 bay music storage. Hard to believe how much AC cables effect this position in the system. Wish I could afford 30th Anniversary here.
I did not think this much improvement was left in my system. If nothing else it proves it’s best to keep an open mind and experiment.
Regarding: Albert, thanks for hosting us again last night for a great evening of
music. The new Allnic M5000 amps are fantastic, as is the Air Tight Opus
After years of setting up phono cartridges, I did not believe that
we would hear a miniscule change in tracking force, but we could all
easily hear a change of 2/100ths of a gram tracking force with the Air
Amazing, and this speaks to the overall resolution of your
Thank you for that ! We all work hard to try and achieve that magical level where the system gets out of the way and you're transported directly to the emotion of the music.
I agree on the new Allnic M5000. They just keep getting better every week. I think the huge custom transformers still have awhile to go to reach 100%. That's normal for all transformers, improve with hours and these are easy to hear as they change.
Next meeting I want to move the tracking 1/100th of a gram heavier, hope to maintain the fragile perfection in the highs but improve the bass like we had earlier in the evening. Maybe even back off the anti skate a tiny bit.
As I posted in reply to Jeff, I have two substantial changes coming for the digital, Allnic D5000 DAC. If you return to hear what the Purist AC contribute I think you will be surprised.
I also want a 3 meter Purist 30th Anniversary AC for the MK3 motor controller. I know it's a bit insane but every time I've upgraded there the improvement pay off, simply stunning what that cable does for the system.
Regarding: Albert, I now have 100 hours on the Purist USB cable and it if f--
fantastic. So open, detailed, harmonically right and full in the mids.
My system is transformed can you believe just this one cable?
I agree. This last Tuesday night with friends in our audio group, my digital was working at a level beyond anything I've ever heard.
My Purist USB is completely broken in now and I found a couple of marginal tubes (and replaced them) in my Allnic D5000 DAC.
Those two changes brought a huge improvement, we listened to several cuts while spinning LPs. I ordered a Purist 30th Anniversary AC for the DAC and the 25th Anniversary that's there now will move to the linear power supply for computer and Data Tale drive bay. I think these two changes will make a startling improvement.
Albert, thanks for hosting us again last night for a great evening of music. The new Allnic M5000 amps are fantastic, as is the Air Tight Opus I. After years of setting up phono cartridges, I did not believe that we would hear a miniscule change in tracking force, but we could all easily hear a change of 2/100ths of a gram tracking force with the Air Tight!

I will have to call Purist and let him know. I don't know if you know him, but Andre Jennings of the Absolute Sound will be coming to my home for a listen in late September. The best Jeff
