There’s really nothing out there that packs equal power and features in a smaller footprint, especially for the price of the Halo. Parasound keeps pulling rabbits out of the hat when it comes to value/$. Just look at their new $599 phono stage. Where else can one find a brand new, American- engineered phono stage with all that adjustability and for that price?
There are smaller and better sounding integrateds at this price point, but none match the Halo’s versatility.
My recommendation is the Exposure 3010S2, with the DAC and Phono modules, though you’d have to give up bass management and tone controls. Anyhow, the Halo isn’t that big compared to most of the popular integrateds in the current market. It’s downright compact compared to many. I would adjust your rack/shelf space rather than adjust the footprint of the amp. Or you can become a serious audiophile and get a tube amp.
