Amp for Dahlquist DQ-10


I have recently discovered this site and appreciate the opportunity to learn about audio from the knowledgable people the participate in this forum.

I have a pair of DQ-10's that I bought new in the late 70's. They always seemed under powered by my Hafler DH-200, but still sounded great. I'm using a Crown IC-150 pre-amp.

I recently purchased an Adcon 555 power amp. That seemed to perk the DQ's up quite a bit and with it my interest in refreshing my system. I'm now considering either replacing the Crown preamp or adding a second Adcom 555 power amp, but I'm not sure which change will give me the most bang for the buck. If the replacement of the preamp is the best route, I'm interested in hearing suggestions of which preamps will mate well with the 555.

Since I will likely be buying used equipment online and won't be able to listen before I buy, I wanted to see if anyone here was willing to offer a suggestion.

I haven't sat in front of DQ 10's in a long long time, but I have sat in front of them in a couple of homes probably 25+ years ago and once in my store. I modded the pair in my store. In the store we put them on Sumo gear, it did a good job on them, the nine was warm and inviting, but in the homes, one was much better, He used a Audio Research Preamp and Kenwood LO7M power amps. This was a very nice combination indeed. I would today, still recommend a tubed preamp that is warm and rich, along with a power amp that is fast and accurate. These old speakers would sing again. Everyone won't like that Adcom amp, but it is alot of bang for the buck, If you like it, run with it. I might recommend a Joule-Electra Preamp. Maybe a Conrad Johnson... Depends on Budget. Good Listening, Tim
The GFP565 is known to be Adcom's best standard line product, however the GFP750 is not their standard line product, it was contracted by Nelson Pass, there are a ton of threads and arguments about it here on Audiogon, but any way you look at it, it is in another league, better than the GFP565.
Hi Laffer,
I recommend that you do everything that you can to audition Adcom gear with your DQ10's. We have all learned the hard way that all of our ears are different, but for me, there is no question that I would develop fatigue fairly quickly with Adcom and Dahlquist. DQ-10's are detailed, revealing and without mods a touch light on the bass, DQ-10's will get edgey with some equipment.
Now after all of that said, If you like the Crown/Adcom combination, forget all the above. The GFP-750 will lunch it in every aspect. Good Listening, Tim
