Hi-Fi stores are few and far between in Wyoming. Mail order is my friend.

How are dynamics with the passive pre? I thought about going that route at one time but decided on the Dared instead. I love the sound of the Dared and want to try and make it work before changing...

organ - Unfortunately my NAD doesn't have the variable input. I'm using the C370 which is essentially the C160 preamp and C270 amp all in one box. It has a variable output for the preamp but no...

I'll be interested to find out if the 12au7's make a difference.

What amps work well with the Dared and SDA's? I love the NAD sound but it may be time to upgrade.

I heard back from Mike at Deltronics. He recommended against changing any resistor values to decrease gain and suggested I look at different tubes. He says 12au7, 12at7 and 12ax7 tubes will work. ...

Thanks H9!

H9 - Did you get my PM? Can you share the schematic for the Dared? I'd just like to learn. I won't pass it on to anyone without permission.
Thanks,
Stew

At this point, I'm convinced my NAD amp doesn't like the high gain of the preamp. I'm using the amp portion of a NAD C370 integrated. I plan to upgrade to a seperate amp at some point but the NAD...

Good idea! I didn't think of that. The volume knob on the NAD is labeled with db attenuation so it might help estimate how much I need to reduce the gain.

As for the tube buffer question, it...

That's the idea. I have too much gain resulting in audible hiss and limited range on the volume knob (6:00 to 9:00). Lower gain or attenuators would increase the range of the volume knob hopefully...

Thanks H9. I'll take your advice and call Deltronics on Monday. I haven't tried a lower Mu tube yet. I really like the sound of the Siemens triple mica's that I'm using and would hate to change. ...

I'd be willing to bet the Maggie's have a lower input sensitivity than the Polks. I think this is starting to make sense. From the research I've been doing tonight, a high amplifier input...

With the tube buffer in line but turned off, the hum is there but I have to be within a couple of feet of the speakers to hear it. That would not bother me. Without the tube buffer (or with it...

I've tried it with original and upgraded tubes, cleaned pins, etc. all to no avail. A better wall socket couldn't hurt but it's plugged into a Panamax conditioner. I've tried it with and without...

On a whim, I just hooked up my Yaqin tube buffer between the Dared preamp and NAD amp.

In my old system, the tube buffer still passed the signal through when turned off but speaker output was...

It arrived Wednesday night and I finally got a chance to listen today. Hum seems a little better but still there.:sad: It's really not that bad but I would like to find a solution. I'm using the...

My Dared is on the way home. Mike at Deltronics checked all the capacitors in the power supply, cleaned up solder joints (power supply, inputs, outputs and volume control) and installed the Auricap...

I spoke to Mike earlier this week. He heard a slight hum but hasn't been able to duplicate what I was hearing. He did find and repair some questionable solder joints in the power supply that could...

I haven't heard anything yet. I'll call next week if I don't hear from them.

H9/daboyz - Glad to know I'm in good hands with Mike at Deltronics. They just called to let me know it arrived and get a deposit.

Carl - I do have a cable box that's connected but I...

I've seen several threads lately talking about hum in the Dared SL2000a. Mine has always had a slight 60 hz hum but I convinced myself it was the nature of the beast. I tried lifting grounds,...

FWIW, The pair I had from 1981 had treated cloth surrounds on the passive radiators and foam surrounds on the mids.

Hope you had a great birthday!

In with #27. Thanks!

Love my 2B-TL's. Spare parts would be nice but parting these out seems like blasphemy. Let someone else enjoy them.
