Re: What DAC are you using with your CJ

None other than the CJ D/A-2b. I really like the sound and it's unlikely to be replaced (unless CJ introduces a new DAC).

I wrote a pretty lengthy review awhile back here: viewtopic.php?f=12&t=205

Re: Old CJ Iron

Very cool setup. I agree, looks "vintage". Goes really well with the room decor. Congrats on the setup.

Re: ET 250S - Modwright LS-100

Hmm, that doesn't make much sense to me. One way I like to think of electronics is that they are small electric heaters. If you really think about the energy consumption, the vast majority is turned into heat (and not actually used for the power output). Also, the 250S should be consuming a fair amo...

Re: ET 250S - Modwright LS-100

This is not specific to the 250S, but temperatures are going to reach maximum/baseline in 15 minutes or under in just about all electronic equipment.

Re: ET 250S - Modwright LS-100

I don't see why it would be a bad match. Quite the contrary, both are tube based equipment so it should give a nice warm sound. Let know what you think of the combo if you decide to pair them up.

Re: Thanking to all of you, dear friends!

That's the kind of room that looks like you walked in one day and walked out 7 weeks later. And I can't blame you, you would have to drag me out of there as well. The CLX's are my holy grail speakers. Awesome setup, congrats roberto.

Be careful with this as you are not grounding the equipment as designed.

Re: PV 9a Break in period after recaping with Claricap capacitor

Beautiful picture btw. Those caps look great. As for your question about cap burnin times. I think this is one of those things that you ask 5 people and get 5 different answers. Some don't believe in it and I've also heard many say it takes 200 hours. I think at 50 hours it should be "settling in".

Re: Used premier 140

First, welcome to the site. It's great to have you. The premier 140 should have not problem driving your 801's. The 801's are not the most efficient speakers but they aren't that inefficient that they would require a crazy amount of power. Even at high volumes you should be ok. I would have no reser...

Re: Help and Embarrassment or Riches to Rags in seconds

Sorry to hear about this event jahatl513. I agree with roberto, that is probably what happened when it was unplugged and replugged. I think this is one of those hard lessons we all eventually learn about having everything off when we are working on (or near) our systems. Hopefully, it won't be too e...

Re: Classic 60se Speaker recommendations

As a long time user of Martin Logan speakers I 2nd roberto's recommendation. Their hybrid design really gives a nice balanced low end for those craving the detail of planar speakers but not wanting to sacrifice lower frequencies.

That would most likely be in the manual (and not the schematic). All conrad johnson manuals can be downloaded directly from their website.

Hi robin hood,
Welcome to the site. I have an evolution 2000 myself. Are you looking for a conrad johnson replacement? Are you looking for something with less power or simply size,... or both?

Re: MF2500 throwing 68 DCvolt out on right channel

Hi runner70. I also have a 2000 Evolution amp and love it. I, unfortunately, do not know its design history in detail. I too would be interested in the sound comparison of this now "older" amp vs something designed more recently. As for mods, one simple cheap mod that can be done and which my unit h...
