Need suggestions on preamp


I’m mainly a headphone listener so when I got the chance to purchase a pair of Magnepan LRS speakers near my home town, I ran with it. I love Maggies and their midrange smoothness and live performance feel. I was able to find a used Parasound A21 for $1200 on Marketplace which was replacing my Adcom 545. I’m now running into a dilemma where I think the Adcom 545 sounded more detailed to me. I listen to a lot of instrumental music that I know well and I’m not getting the same level of detail as I’m getting with my headphone setup which is running balanced from my RME ADI-2 DAC. I’m using more expensive Audience AU-SX interconnects on those but even when running the RME direct into the amp (since it has volume control) I’m not getting the level of resolution I’m used to with my headphone setup (Hifiman HE1000 with a Serbian Audio HSA-1B amp).

I think the issue might be related to my preamp. I bought a Schiit Saga+ and despite running good NOS tubes or trying out passive mode I’m not getting the resolution I’m looking for. I’m looking for a recommendation on a preamp that costs between $1,000-$2,000 that will max out the resolution of the Parasound while keeping it’s effortless flow and naturalness in tact. Maybe the problem is the speakers and I really should have gone for the LRS+ or 1.7s? I know the room plays a huge role with Maggies but I live in a small apartment so for now I’m looking for any suggestions that can be fixed with gear. Thanks for any help!

I have a pair of Aerial Acoustics Model 8b floorstanders in a large room. They are relatively inefficient, 4 ohm speakers and power hungry like Maggies, but a more traditional 3-way rear ported woofer design. The amp is a well maintained Proceed HPA-2 (a Levinson design), putting out 250w/ch at 8 and 500w/ch at 4 ohms. The amp is a balanced unit like the Ayre preamp and they are a good match. I listened to Ayre amps when I purchased the preamp, but kept the Proceed. Felt it had a bit more meat on the bones, a more full bodied sound. You can find reviews of both the speakers and amp online.  

I’ve got Hifiman Arya Stealths so have an idea of the level of detail you’re looking for, and I was able to get there with my big rig so it’s definitely doable and highly doubt the preamp is the limiting factor here. I think the amp and possibly the speakers are the source of the problem as the Parasound, although a good amp, is reputed to be on the warm side. I had this Bryston pre paired with a similar McCormack amp to the one below and would highly recommend them given what you’re looking for.

Pair them with speakers like these Monitor Audio Silvers (or maybe monitors since you have a small room) and you’ll likely get all the detail you’re missing along with excellent imaging/3D soundstage. Just some ideas FWIW, and best of luck in getting what you’re looking for.

My suggestion is the Pass Korg B1 Pre Amp.

Buying one built by a competent EE, will be the best advised as the approach to a purchase. There are also models now having undergone tweaks to the Circuit and VC. I am familiar with the differing builds that can be produced and am always impressed. This option will keep you well under budget. 

@soix - yes people who have heard the Hifiman headphones (really any variant) Arya, Susvara, SE or HE1000 will know what I’m talking about. Wide soundstage with lots of resolving micro detail. Monitor Audio is supposed to be brighter so would make sense that they would resolve better. I probably got the wrong speakers so have to decide if I just want these for their great midrange. I love the LS3/A variants like the Graham Chartwells as well as Falcon Gold Badges, Harbeths, etc. so maybe that’s where I’ll settle and realize the limitations (or looked at different the strengths) of my current setup.
