Hi everybody! I’m new to this forum. I discovered it searching for infos and opinions about the V280 that I’m going to buy used but mint. I want to use it with HD800 and I’d like to use the Astell & Kern SR25 as DAP without an external DAC at least initially.

I’d connect the A&K using its 2.5mm balanced out with a “2.5mm TRRS male to 2 XLR male” cable and activating the line-out on the player as well.

Now my questions/doubts.

Since this kind of connection is no grounded can I have some hum issues?

How must I set the XLR inputs on the V280 (I’m referring to the internal jumpers, ground/lift/chassis)?

Also I’d like to use the balanced headphone out (I have a proper HD800 cable) but if I’ll connect the A&K through its 3.5mm stereo out (of course in line-out mode) to the SE inputs of the V280, the balanced headphone out still makes sense or it will be the same quality (but only maybe more volume) of the unbalanced out?

Thanks so much in advance!

I am not familiar with the A&K but I can provide some general info on the V280.
Don't adjust any jumpers until you try it out. Both balanced and unbalanced inputs are available from the balanced output. The V280 has loads of gain, so don't worry about using the unbalanced inputs.

Try all combinations of your cables and DAP outputs and just see what sounds better. The quality of your cabling is usually more important than whether you use balanced or unbalanced.

Hum is not generally a problem. The manual is pretty detailed regarding the use of the jumpers if you run into an issue.

What voltage used for opamp in v280? +-18v?

Just write to info@lake-people.de

Hi Fegefeuer, I want to piggy back off a pre-gain question. I did search and saw you running -14db? Do I push the switch -12 and -6 for both channels so 4 switches in total?

Just wondering if I can go even further? I'm running XLR balanced out on the TH900's and they're really sensitive headphones.

Cheers.

-14db is max when pushing -12 and -6, correct.

Can't go lower than that. V550/590 can go down to -18db however

The V280 is kinda too much amp for TH900s. Try running single-ended.

Yeh I'll probably get nicer single-ended cable made.

Do you know if there are any theoretical impact on SQ if 1) I run it on pre-gain 0db vs -14db? or 2) volume pot on 7-8 o clock position vs 12 o'clock position?

Thanks

I don't know, but I guess the less pre-gain the better

It certainly helps to have a useful range of adjustment. The V280 has tons of power down low.

I did not know that was a thing. I have a V220 and use my Grado's in -12Db's and still can't go much past 10:00.

How many dual and single opamps have v280?

 

[Ichos]

Hey guys look who is here

This is the real V280 successor.
Price €999.

Would be great to hear your impressions of V222 vs V280.

No, not until I see some specs and the back panel
