What is the good brand or type of grease you'd recommend?

Also, can I use the same one to lubricate a tape deck mechanical components? Which parts you'd use the lubricant on, in case?

Hi everyone,

Sorry if this question sounds basic, but my only experience with a BT receiver/DAC is an older Audioengine B1, which I only use as both receiver/DAC when I stream digital music from my phone or laptop, and occasionally I connect my TV to it for movies.

Now I’m thinking of upgrading to a better DAC, and the FiiO Warmer R2R keeps coming up with very good feedback. I only realised afterward that it does not have a built in Bluetooth receiver.

So my question is: would pairing it with the FiiO BR15 be overkill, since the BR15 seems to be much more than a Bluetooth receiver and also has its own DAC? Or would that actually be a sensible match?

If it would work well, what would be the best way to connect the two devices?

The Warmer R2R supports the following digital inputs:

USB Type C, up to 384kHz/32bit.

Coaxial, up to 192kHz/24bit.

Optical Toslink, up to 96kHz/24bit.

It has RCA and XLR line outputs, but I won’t be able to use the XLR outputs into my Musical Fidelity A3 CR preamp because it only has RCA inputs, not balanced inputs or optical input.

The BR15 has the following:

Bluetooth 5.4 with aptX Lossless, LDAC, aptX Adaptive, aptX HD, SBC, AAC, and LC3.

USB C inputs.

Optical input.

Coaxial input/output.

Balanced XLR and RCA analogue outputs.

So my questions are:

Do I really need both devices, or would the BR15 alone be a major upgrade over my current DAC/Bluetooth receiver?

If I bought both, what would be the best way to connect them: XLR, optical, or coaxial?

If the BR15 is overkill with the Warmer R2R, could I just use a cheap Bluetooth receiver into the Warmer R2R via RCA and get the same quality?

Thank you very much for reading all this and for your help.
