Comparing Budget Class T and Class D amps

Got an opportunity to listen for an hour this afternoon.

The Allo has been powered up using the stock 19vdc since last night. It has definitely improved from then until now.

I want to let it settle in for a couple more days before doing any critical listening.

From the mid-bass up, it is clean and articulate. Good detail. I am not getting the same low end foundation as I get with the Topping TP60 or the TPA3250/LS10A. Hopefully, the bottom end will fill out a bit more.

Will end up trying my new variable linear PS set to 19vdc over the weekend.

More to follow. :)

Well, plans changed rather suddenly when the basement flooded up through the downstairs shower on Sunday. Luckily losses were at a minimum - some records I had boxed up to donate to the ASPCA Thrift Store and some wood shelving. Bunch of drywall also needs to be replaced. Also had to take up a bunch of carpet and pad. The downstairs is definitely getting a facelift now.

Getting the full report from the plumbing company on Monday which will determine if I go after my insurance company or the city to get reimbursed.

Just sitting down this morning to relax with my morning tea and listen to the Living Room system.

With another week of warm up, the Allo is settling in nicely. My bride pegged it when she stated that the Allo sounds "crisper" than the Class T and Class D amps (the KingKo remains her favorite sounding LR system amp).

Clear, articulate and fast are the terms that come to mind. It's close to that "too much of a good thing" line but does not go over. It has balanced out, to a noticeable degree, from last week.

More listening to do. :)

Glad damage was not higher. For your initial evaluation are you using all of these strictly as they come or are you using the Saga preamp in front?

Using the Saga as the preamp for all of them. :)

I originally ran the Nobsound JLH1969, Topping TP60 and TPA3250/LS10A amps by themselves and found that all three sound better with the Saga. The TP60 is the only one if the three that I would say works well as an integrated amp (two inputs) and, while it still benefited from being fronted by the Saga, it was close.

Have not yet run the KingKo or the Allo without the Saga.

The Tangents continue to sing sweetly. They have this ability to weave a tapestry of beautiful music in the room (within reason, the RS2 is not going to provide the sheer power and scale of the big horns). A more"intimate" experience, if you will.

The KingKo combines with the Tangents to weave a beautifully layered and open view to the music. As it stands now, none of the Class T or Class D amps have equalled the KingKo (must keep the price difference in mind).

As always, just my opinion. :)

So -- full disclosure -- this six dollar Chinese closeout amplifier from PE is not Class T or D; it uses a push-pull chip amp...
but it was also six dollars. Another six dollars for a closeout 12V 3A P/S from PE (albeit switchmode). I sent the amp, P/S, and ancillary cables to our son in VA so he could test/use a pair of Polk Audio RTA 8TL loudspeakers he'd found at a local thrift store.

He sent me a photo of this high end hifi setup earlier today, so I thought I'd share it in the context of this thread.
