My audio updates stream of consciousness

That is true.... I'm sucked into it, and don't see myself leaving anytime soon, but I'm looking for a solid state amp that can keep me happy during the day in my office/audio room, that I can leave on all day. I know nothing will replace my 421a or 45, but the Atom had some nice qualities, I just don't need all-in-one. I have some options I'm looking at researching over on audiogon. Budget under $2k
Are you looking for an integrated or power amp? If you want leave it on all day, Class D or Class AB seems to be in order.

So latest update.. maybe I should start doing YouTube videos, so I can just ramble on and play some tunes instead of typing everything out.

Not sure why I did this, but wanted to try a different type of speaker than my Omegas which I've been using for the past 4yrs. After some research I decided to give Daedalus a try and find a pair of used DA1.1's but with the v2 upgrades that were done in 2017. The first thing you notice is 1. they are 100lbs each!! :wtf:, because 2. they are an heirloom quality build. Solid wood (no mdf, veneer, etc), dovetail joints, and just a commanding presence in the room. they are rated at 97.5db and 6-ohm flat.

Couple interesting things to note...
  • even though they are rated at 97.5db I've found they tend to like the solid state power of the Atom (40wpc) better than my 3wpc tube gear. I have a 12wpc Class A single ended Solid state amp arriving Friday to try out.
  • They dig low enough (around 35-40hz) so I doubt I will need the REL subs with them.
  • they DID NOT like my higher gauge speaker cables that were meant for the efficient Omegas (17awg). I swapped out to a new pair of Audio Art PCs I got that are effectively 11awg and the sound was like night and day. I couldn't believe it, synergy definitely matters
  • The Omegas seem effortless to drive (no crossovers) vs the Daedalus (HUGE crossover network), so I'll be trying different types of amps out to see what works best. testament to Omega, they seem to be more versatile, from a 1.5wpc 45 SET to 80wpc solid state
 
Beautiful speakers.

Your Daedalus speakers are rated 97.5 dB/2.83V/6ohms = 96 dB/w/m. The single driver versions of your Omega speakers are 98 dB/w/m and there is no reason to believe the dual driver model is any more sensitive, despite what Louis indicates for his other dual driver models. If both of these numbers are to be believed, they should both be easy to drive and should be pretty close in level when driven by the same amp at the same level of gain. This has not been your experience thus far. Some thoughts:

1. I’m not 100% on the sensitivity rating of the Daedalus. Almost everyone overstates sensitivity and neither of these makers specify frequency response nor +/= dB. I’m not sure of the crossover topology, but it is bleeding off some of the sensitivity. Additionally, to get the sort of bass you detect requires some sacrifice in sensitivity. That being said, the tuned live cabinet may increase bass output.

2. While the sensitivity may still be comparatively high, it seems to require more current than your SET can provide. The Naim has a beefy power supply with good current delivery. This is also borne out by the night/day difference in going with larger gauge cables. It should be noted that a number of Daedalus owners prefer the Modwright KWA150.

3. I’m not sure how happy you will be with a 12wpc Class A amp with these speakers; they seem to want some power. I did see a Krell KSA50S on USAM in your price range.

4. All Omega speakers, even the dual driver models (I own a pair of single driver and dual driver RS5 Omegas) are not full range if you value energy and fullness in the 50-100hz region. Forget about deep bass. I would also argue that the sensitivity rating is really a midrange (500-3,000 hz) sensitivity rating.

Thanks @Roscoe65

its been fun experimenting. I have 7 more days to decide if I want to keep the Daedalus. I know the Omegas are a bit different but their versatility with amps is pretty nice, and I really enjoy flea watt tubes. I’ll have to see if the Daedalus are worth switching to solid state.
 
so after a hiccup w an all-in-one preamp, we won't mention, the Niam Nova that I passed on, came back up for sale. . . . . funds sent today.

it should be arriving by the weekend, fingers crossed but likely Monday. i kind of just know it will be a winner because I read every positive Nova/ Atom review available online.. and that's never backfired, ever., :D except recently.

On the plus side, I'll be able to sell off 4 boxes, a pile of cables.. pick up some speakers and 'pocket', at least temporarily, some $.

a year ago, if someone told me i'd be going back to a one box solution, I'd have laughed hysterically and in doing so, bobbled another $100 dollar tube on the granite edge of a speaker stand.. (smaash) just to prove how truly funny I thought that was.

the idea of having just one box, connected to a hard drive and a pair of speakers.. >> soothing. Even if it's just for a little while, I'm looking forward to the reset.

Well why we do this.... The Daedalus experiment is over. Sent them back to TMR.

Main reasons being...
1. I love my flea watt single ended tube amps, 421a, etc, and they just didn't sound right on them
2. I think I prefer the immediate sound of full range/single driver speakers, like my Omegas.
3. My Omegas sound wonderful even with 1.5wpc amps.
4. I didn't want to give up my tube listening, even though the Daedalus excelled with good solid state.

Even the Naim Atom sounded great on the Daedalus. The whole purpose of the Daedalus was to 'add' to my setup to enjoy both my tube and solid state. I could have easily kept the Daeduls, but it would have made me change everything else, and flip my plan.

I also started to feel they might have been too big for my room.

On a new note... I have a new amp in the chain to try out.....
 
I’m not sure they were too big for your room. A number of factors lead me to believe that this speaker really does better with >100 wpc.

If you want to stay with your low power amps the Omegas will satisfy your needs. One thing to heart in mind that if you are using a SS amp that doubles power when impedance is halved your 1.5 way Omega speakers may be boomier than you would prefer. When you halve the impedance in the bass region, you may draw twice the current with a solid state amp, resulting in + 6dB rather than the +3dB you experience with a Tube amp.

If you want to elevate this level while staying with a <5 wpc amp you may wish to explore an Altec two-way. 414 based speakers do well in smaller spaces and while they are not the last word in bass, they will provide more midbass energy than the Omega. A 414A based speaker will have sensitivity of 99dB with a 16 ohm impedance. See the Altec two way sticky thread for more ideas.

Thanks @Roscoe65

They just felt too big for me in the physical space, not sounding too big. I plan on keeping the Omegas, they are satisfying, unless something displaces them along the way. The fun of the hobby. The bass impedance makes sense based on my listening impressions.

I'll keep the Altec idea around. I've always felt intimidated by the whole Altec thing :D maybe if I can find something completely refurbed, etc.

Have you considered Cube Audio?

My first thought was uber bucks... even used, but rarely come up, but I'd have to do more research as they are only rated at 90/91db

Another option is Coherent, but they rarely come up used as well. My budget is <$5k

I hadn't heard of this brand. They look super interesting though. I'll have to put these on my list and see if I can find pricing. "The Ten" is probably the only one I could ever dream to afford.

Latest amp tryout…

Valvet E2
Single ended Class A solid state
12wpc into 8ohm

BD93796E-DE8F-48B5-A14C-1BCA09255676.jpeg

Beautifully simple amp. Current model is the E3, but Valvet also makes mono blocks and a matching preamp. Slick feature - the power switch is directly under the V on the front underside. For electronics like this that I’m not going to leave on 24/7 I love that the power is easily accessible from the front and not the rear.

Sound wise it’s been compared to First Watt SIT-3, I.e. close to tubes but not tubes. It’s very smooth and definitely on the warmer side. Detail is all their though. Depending on speakers can come across as too dark or rolled off up top. But mainly it’s smooth and non fatiguing. Can leave it on all day while I’m working and not have to turn it off to give my ears a break.
