System Upgrade


Leben CS600; Harbeth Plus 5s; PS Audio with Bridge II linked via Blue Heaven USB; Chord Clearway interconnects and speaker cables (not bi-wired).

Sounds good but "flat" and I find myself having to turn up the volume almost halfway to get any "presence".

What am I missing, if anything?

Than you.

Thank you. It was set correctly. I was just experimenting with other settings. I bought the Leben second hand. Will speak to my Harbeth dealer. Thanks again.

Now we may be getting somewhere. Which tubes are installed? Do you know how many hours/how old they are? Do you have a spare set of the 6cs7’s input tubes or el34/5881/6l6 power tubes?

When you are playing the amp with the harbeths does it sound great up to half volume and then flatten out or does it sound flat all through the volume range? Are you running your dac gain full or is it backed off? Just a stretch but maybe the input is overloaded. I dont know anything about the output voltage of the psaudio.

Something you might consider is plugging your dac into the amp direct rca jacks. Those inputs bypass the pre section and the volume control is active in order to match gain appropriately with the source. BEFORE doing so be certain you have turned the volume on you psaudio waaaay down.

isnt this hobby a blast? LOL. Hang in there, troubleshooting will either be a learning experience or a confirmation. Both will serve you well in the future, regardless of the equipment you have now.. or then. Peace.

I saw where you listed your Leben CS600 for sale at a very aggressive price and it sold same day. Congrats.

What amps will you be auditioning to go with your Harbeths? I have read where Alan Shaw is somewhat amplifier agnostic. Depending on what you are after, maybe a pair of Schiit Vidar monobolcks and a Schiit Freya + preamp might meet your power and dynamic needs. They are really overachievers unless you are leaning toward an integrated. They are also incredibly easy to deal with, place, setup and return in the event they aren't your cup of tea. Best wishes and good luck in your search.

Saw too that  you sold your Leben, we wish you would have tried some different cables first but that is a different matter.

We also saw you are in New York City. Our shop, Audio Doctor is right across the water from you 3miles away in Jersey City.

We have one of the best selections of gear on the East Coast:

We have a few amplifiers that you might really like, the new Krell K300i at $7k is a 150 watts Class A in power, and is very tube like in its presentation. It is also quite compact. 

We also have the Norma Revo 140 another great intergrated amplifier very open and full sounding at $7k.

We have the Italian Tube line Synthesis A100T which is a $7k 100 Watt KT 66 another stunning sounding tube amplifier.

We also have the Micromega and Naim products. 

Plus Electrocompaniet, T+A. Cary, Conrad Johnson, and a few others.

Thank you All. The Leben sold very quickly and I am pleased with the sale - although I hate to see it go because it was a great amp, perhaps not for my setup.

My Dealer is suggesting the Gryphon Diablo 120 or 300 or the Luxman L-509x. Looking at the Forums it seems that the Luxman is an excellent paring for the Harbeths.

Need to make sure that my next Amp is the right fit.
