Can I ask you the model of your new 1000,00 headphone amp/pre amp.
Is it also a DAC?
I use this 100 dollar gadget Amazon.com: Qudelix-5K Bluetooth USB DAC AMP with LDAC, aptX Adaptive, aptX HD, AAC (Dual ES9219 3.5mm Unbalanced & 2.5mm Balanced Output) : Electronics which receives the audio through Spotify I have close to 250 playlists. My phone, a cheap Samsung lower tier (350.00) smart phone, is used as my digital audio player (DAP) and sends the music files via blue tooth to my Qudelix DAC/AMP.
As you can see in the photo on Amazon, the Qudelix has 2 outputs. One is a 3.5mm unbalanced and one is a 2.5mm balanced. I use the 2.5mm balanced for my headphones which is the Sennheiser HD650. The 3.5mm I use for my Soundboks Go portable speaker. SOUNDBOKS Go | Portable Bluetooth Performance Speaker
I use the headphones occasionally and the Qudelix DAC/AMP performance far exceeded my expectations.
Although the Quedelix receives audio from my DAP via blue tooth signal I use a hard wire to connect the headphones or speaker. I use a 2.5mm balanced Audiophile Ninja headphone cable Custom Headphone Cables ⋆ Audiophile Ninja and for the speaker a generic 3.5mm male to male interconnect.
The majority my use of the Qudelix is with the speaker when I am working. I drive a tractor trailer semi 8 - 12 hours per day/night and the audio using the Qudelix and Soundboks go is amazing. A little lacking in the mid range which I fix with the Qudelix on board PEQ and the Soundboks Go EQ.
You could try out the qudelix and if you do not like it Amazon Europe probably has the same 30 day free returns as Amazon USA.
Yes I spend hours on the road listening to music while making money......
