Tube Rolling for Convergent Audio SL1 Preamps
Just a quick correction on my previous post. I have the CAT Ultimate MK2 not the CAT Sig MK2.Bart 
Tube Rolling for Convergent Audio SL1 Preamps
I guess on different days, Ken has different opinions.He has told me that Telefunken smooth plates are the best he has heard in his preamps. I think he hasn't done much experimenting. There are lots of tubes that will vastly outperform Telefunkens... 
Amps for Avalon Osiris CAT JL3, Boulder 2060, Dart
I haven't checked this thread in a while. Hodelrecords,the Avalon Osiris is pretty flat at 4 ohms with a minimum dip to 3.6. The CAT JL2 will drive any Avalons easily and do the bass very well. They have a OTL or SET like mid and you should give t... 
Jerry Ozment has a new dac out...
Hi Guys I spoke with Jerry again this week and he said that the upgrade would cost about 300 to 400. He said to call back in a month to see when he would be ready to take orders. Bart 
Audio Logic 24MXL compared to Audio Logic 34MXL
Pubul57, can you describe the pros and cons of the CAT Ult MK2 and Placette RVC comparison. What tubes did you use in the CAT? I have found that the stock tubes are crap.I have done extensive tube rolling in the past year and have settled on some ... 
CAT Ultimate/Tube rolling
Some thoughts on tube rolling in the CAT Ult MK2 and CAT JL2. I have settled for now on Amperex 6922's in the CAT Ult and JL2. The cathode follower (v10) is a pinched waist Amperex 6922 PQ. I am using Raytheon 12AX7's (black plate square getter 19... 
Choice of tube amp?
Mibviking, you should auditon the CAT JL2 (I think the JL3 is overkill). I purchased one used about three months agoand it is the best I've ever heard. I am a long time user of VTL, Manley amps and did hear the VTL S400 at the show in NYC two year... 
Jerry Ozment has a new dac out...
I spoke with Jerry yesterday regarding the upgrade from the 24MXL to the new 34MXL. He said that the transformer was upgraded and the components (caps, resistors) were now matched in house instead of by the manufacturer. He said it was a noticeabl... 
CAT JL-2 mk II vs VTL S-400
I have run the Avalon Ascent MK2 with Manley 350's and the purchased the Avalon Osiris and ran them on Manley 350's.I then purchased the CAT JL2 and used it on the Osiris. The CAT easily betters the Manley (basically a VTL). The key with the CAT i... 
Audio Logic 24MXL compared to Audio Logic 34MXL
Thanks for the response Rcprince. Do you have Jerry's phone number? The number in my 24MXL owners manual is no longer correct. I looked at the specs from the new DAC and mine and see no real differences. I was hoping for at least a cap and resisto... 
Jerry Ozment has a new dac out...
I have a 24MXL, is it upgradable to the 34MXL? I tried to call Jerry using the phone number in the owners manual but the number was discontinued with no forwarding number. Can anyone provide the phone number he is currently using?I also started a ... 
Favorite Tube Speaker Match
Jburidan, I agree wholeheartedly with your post. That's why I love tubed equipment. Just by rolling the signal tubes you have whatever sound you desire. Bart 
Favorite Tube Speaker Match
CAT JL2, CAT Ultimate MK2 and Avalon Osiris. I tried a Levinson 436 monos but I will probably never venture solid state again. Avalons need tubes.Bart 
CAT Preamps vs Amps
Rayhall, I am describing the sound I heard with the CAT U2in my system with stock tubes. As stated, replacing the stock 6922's and 12AX7's with Amperex was transformational.I was considering the preamp for my next upgrade but am now looking to the... 
CAT JL-2 amp upgrade
Johnny, thanks for the info. Has anyone experimented with tube rolling the output tubes in their CAT amps? Ken told me I was asking for trouble and I would end up blowing up the amp. I ordered the SED Svetlana 6550C tubes today from Upscale Audio....
